Homicide perpetrators with psychotic illness found not criminally responsible in Turkiye and Russia: An international comparison.

OBJECTIVE: The primary objective was to conduct a comparative analysis of homicide cases and their perpetrators with psychotic illnesses in samples from Turkiye and Russia to elucidate contextual similarities and differences, and providing novel perspectives to enhance international research in this field. METHOD: This cross-national retrospective study, conducted at forensic psychiatric centers in Istanbul, Turkiye, and Chuvashia, Russia, involved individuals with psychotic illnesses (ICD-10 F20-F29) who were deemed criminally non-responsible for index homicide offenses between December 2012 and December 2022. The sample included 92 Turkish patients and 29 Russian patients who were compared for background, clinical characteristics, and each homicidal act. RESULTS: Binary analyses revealed that Russian subjects were more educated, had more lifetime suicide attempts, longer illness duration, had acquaintances as victims more frequently, higher rates of blunt traumatic homicides, higher rates of intoxication with alcohol or substances, and lower rates of experiencing delusions at the time of the index homicide compared to their Turkish counterparts. Multivariate analyses indicated that more years of education, a greater frequency of lifetime suicide attempts, higher prevalence of intoxication and a lower rate of delusions at the time of the homicide were associated with belonging to the Russian group. CONCLUSION: Despite several similarities, the remarkable differences between the two samples underscore the importance of international research in enhancing our understanding of mental health, homicidal offense and offender characteristics in the sociocultural context.

Endovascular recanalization of infra-popliteal TASC C and TASC D lesions in patients with critical limb-threatening ischemia: a single-center experience.

PURPOSE: The present study aims to (1) assess the technical success and limb salvage rates of endovascular therapy in patients with critical limb-threatening ischemia (CLTI) and infra-popliteal Trans-Atlantic Inter-Society Consensus (TASC) C/D lesions according to the updated 2015 TASC II classification and (2) to present our institutional experience. METHODS: A single-center retrospective study was conducted on patients with TASC C/D CLTI who underwent endovascular treatment between 2012 and 2017. The follow-up protocol consisted of Doppler ultrasound conduction every 3 months for the first year unless patients showed symptoms of CLTI. Patients with at least 1 year of follow-up data were included in the study, and if applicable their 3-year results were evaluated in terms of primary patency, absence of amputation, amputation-free survival, and overall survival. RESULTS: A total of 248 patients and 287 limbs (238 TASC D lesions and 49 TASC C lesions) were treated via infra-popliteal percutaneous transluminal angioplasty. The overall technical success was 87%, the primary patency rate was 41.5% in the first year, and the freedom from amputation rates were 80.8% in 1 year and 67.7% in 3 years. CONCLUSION: In patients with infra-popliteal arterial occlusive diseases, endovascular treatment methods demonstrate a high rate of technical success and favorable outcomes in limb preservation.

Treatment adherence in forensic patients with schizophrenia spectrum disorders discharged on long-acting injectable antipsychotics: a comparative 3-year mirror-image study.

In this retrospective 3-year mirror-image study, 81 patients with schizophrenia spectrum disorders (SSD) were categorized according to whether they were prescribed long-acting injectable antipsychotics (LAI) or not upon discharge from the inpatient forensic psychiatric unit. Antipsychotic adherence, which was staged based on the 'proportion of days covered' method, as well as other clinical outcomes was compared between pre- and post-index mirror periods. In both Oral-only (n = 46) and Oral + LAI (n = 35) groups, the number of hospitalizations, convictions and months spent in the hospital were significantly lower in the post-index period than the pre-index period. Differences in these three variables between pre- and post-index periods were NS between the two groups. A mixed effect ordinal logistic regression model with random intercept showed that the odds ratio of obtaining a higher treatment adherence score in the post-index period was more pronounced in the Oral + LAI group than in the Oral-only group, considering adherence at baseline and the length of stay during the index hospitalization as potential confounders. Discharge with LAIs in a forensic psychiatric cohort of SSD was associated with a greater mid- to long-term improvement in antipsychotic medication adherence compared to discharge with oral-only antipsychotics.

Clipping of a Rebleeding Ruptured Aneurysm After Woven EndoBridge Treatment.

AIM: To present the clipping of a ruptured aneurysm in the M1 segment of the right middle cerebral artery after rebleeding, which was treated with Woven EndoBridge (WEB). CASE REPORT: A 68-year-old male patient with known hypertension, coronary artery disease and benign prostatic hypertrophy was admitted to our clinic after a ruptured aneurysm of 4.5 mm in the right middle cerebral artery M1 segment and subarachnoid hemorrhage were detected in the emergency room imaging after syncope at home. WEB device was placed into the aneurysm in the patient who was planned for endovascular treatment. After 3 days of the procedure, neurologic examination showed regression. In the brain computed tomography imaging, it was observed that there was an intraparenchymal hematoma of 4,5 cm in the right temporoparietal region and the aneurysm, which had been treated with endovascular WEB, was ruptured. The aneurysm was clipped in the patient for whom emergency surgical treatment was planned. CONCLUSION: As a conclusion, re-bleeding can be seen after aneurysm treatment with the Web device. If it is planned to re-close the aneurysm treated with the web device with a surgical clip, the pressure created by the device against the vessel can be reduced with the additional clip.

Profiling Homicides Based on Impulsive or Proactive Natures in Male Schizophrenia Patients.

The main aim of this study was to ascertain whether a relationship existed between the modus operandi and motivation of homicide, clinical characteristics, and psychopathic traits in schizophrenia. Forty-seven male homicide perpetrators with schizophrenia were included in the study. We classified types of homicide perpetrated by the patients as predominantly impulsive (n = 27) or proactive (n = 20) in nature. We also evaluated the psychotic motivation accompanying the homicide. Forty-four (93.6%) of the homicides were psychotically motivated. The victim was a stranger in only 8.5 percent of the homicides. Use of firearms as a killing method was significantly higher in predominantly proactive homicides (30%) compared with impulsive homicides (3.7%). Infidelity delusions were more frequent in proactive homicides than in impulsive homicides. According to regression models, a predominantly proactive homicide was significantly associated with being married, older age at illness onset, killing with firearms, infidelity delusions and a high PCL-R affective facet score in univariate analyses. Multivariate analyses showed a significant association with infidelity delusions and a high PCL-R affective facet score. Our results confirm that certain predispositions, as well as contextual factors, may be associated with the violent subtype of homicidal behavior in perpetrators with schizophrenia.

Diagnostic Yield of Transabdominal Ultrasound-Guided Core Needle Method in Biopsies of Pancreatic Lesions.

ABSTRACT: In this study, it was aimed to contribute to the selection of the method to perform pancreatic lesion biopsies.Data of patients, who had undergone a percutaneous biopsy because of pancreatic masses in our institution in the period between January 2015 and November 2019, were evaluated retrospectively. The percutaneous biopsy method, the type of needle used in the procedure, and periprocedural complications were listed. Pathology and cytology reports in the archive were reviewed, and biopsy results were divided into 3 groups as benign, malignant, and inadequate. Of 308 patients included in the study, the diagnostic accuracy was verified in 124 patients through the assessment of surgical outcomes, results of biopsies from metastatic lesions, or follow-up findings. The verified results were classified as true-positives and true-negatives.Of a total of 308 patients included in the study, 23 underwent a fine-needle aspiration biopsy (FNAB) and 285 underwent a core needle biopsy (CNB). No statistical differences were observed in sample acquisition success and complications between the groups.Of the lesions with a confirmed pathological diagnosis, 67.74% were malignant and 32.26% were benign. The diagnosis was correct in 107 of 112 CNB patients (95.54%) and 9 of 12 FNAB patients (75.00%). When the success of the 2 methods was compared, it was found that outcomes of CNB were statistically more successful compared with those of FNAB.A transabdominal ultrasound-guided percutaneous CNB is a safe method with a high diagnostic yield to perform a biopsy of the pancreas.

Electrocardiographic Markers of Arrhythmogenic Risk in Synthetic Cannabinoids Users.

Background: Synthetic cannabinoids (SCs) users appeared to have heightened risk for cardiac arrhythmias; however, current line of research is insufficient in terms of demonstrating both conventional and novel electrocardiographic arrhythmia risk indicators in this population. Objective(s): We aimed to investigate P-wave dispersion (Pwd), corrected QT interval (QTc), QTc dispersion (QTcd), Tpeak-Tend (Tp-e), Tp-e/QT ratio, corrected JT interval (JTc), and JTc dispersion (JTcd), which are shown among the risk factors for emergence of an arrhythmia, among SCs users, suggestive of possible adverse effects of SCs on the cardiac rhythm. Methods: Forty-one male SCs user patients who met Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) substance use disorder criteria and 41 healthy male controls included in the study. Substance-related characteristics were recorded. Electrocardiography recordings under standardized procedure of all participants were performed and arrhythmia risk markers were calculated from electrocardiograms (ECGs). Results: Age and heart rate per minute did not significantly differ between the groups. SCs user group had significantly higher Pwd, QTc, QTcd, Tp-e, Tp-e/QTc ratio, JTc, and JTcd values compared with controls. Among risk markers, only Pwd was significantly correlated with duration of SCs use. Conclusions: Alterations in ECG-derived markers of arrhythmia, which are acquired through an easy and cheap method, should be evaluated for the prediction and prevention of severe cardiac conditions in patients with SCs use.

Impulsive and aggressive traits and increased peripheral inflammatory status as psychobiological substrates of homicide behavior in schizophrenia

Background and objectivesAn association between inflammation and psychopathological domains of psychotic disorders is widely acknowledged; however, the involvement of inflammatory processes in the underlying pathophysiology of violent behavior in schizophrenia is yet to be elucidated. In this study, we aimed to address the differences in impulsive and aggressive traits as well as C-reactive protein (CRP) to albumin ratio (CAR) as a marker of inflammation between schizophrenia patients with a history of homicide and those without any history of interpersonal violence or criminal background.MethodsThe study population consisted of 80 male DSM-5 schizophrenia patients who were classified into two groups: homicidal (n=40) and non-violent (n=40). Impulsive and aggressive traits were evaluated with Barratt Impulsivity Scale-11 (BIS-11), and the Buss-Warren Aggression Questionnaire (BWAQ), respectively. For the calculation of CAR, the CRP and albumin levels were obtained from the file records of routine blood screenings performed in the month before the patients were included in the study.ResultsWhen adjusted for age, all subscale scores of the BIS-11 as well as BWAQ Total, Physical and Hostility scores were significantly higher in the homicidal group than in the control group. CRP and CAR were significantly higher, and albumin was significantly lower in the homicidal patients than the controls when adjusted for age, body-mass index and smoking status. Univariate and stepwise multivariate regression models indicated that BIS-11 Non-planning, BWAQ Total, BWAQ Hostility and CAR were independent predictors of belonging to the homicidal patient group, after stepwise adjustment for all potential confounders.

Effect of an Information Video before Thyroid Biopsy on Patients' Anxiety.

AIM: To investigate the effects of video-based information on the anxiety of patients who underwent ultrasound-guided thyroid fine-needle aspiration biopsy. METHODS: Fifty consecutive patients who underwent thyroid fine needle aspiration biopsy were included in the study prospectively. Patients were divided into two groups before the biopsy. 25 patients in Group 1 received only written information about thyroid biopsy. In Group 2, 25 patients received video-based information along with written information. Baseline anxiety of all the patients was evaluated prior to procedure using STAI-S and STAI-T questionnaires. After the written information was provided to the patients in group 1, the STAI-S questionnaire was repeated. In the same way, group 2 patients were asked to repeat the STAI-S questionnaire after written and video-based information were provided. All patients were asked to evaluate pain during biopsy using visual analog scale (VAS). RESULTS: There was no significant difference between the groups in terms of age and gender. Although the VAS score was lower in group 2, there was no statistically significant difference between the two groups. When the groups were compared in terms of basal anxiety scores, STAI-T was similar in both groups (p = 0.708). Although STAI-S values were similar in pre and post-information patients in Group 1, the STAI-S values in group 2 were statistically significantly decreased. CONCLUSION: The video based information provided prior to thyroid biopsy draws the attention as an effective and easy to apply method to decrease the anxiety of the patients.

Radiology guided antegrade GASTROSTOMY deployment of mushroom (pull type) catheters with classical and modified methods in patients with oropharyngeal, laryngeal carcinoma, and anesthesia risk.

OBJECTIVE: The aim of study is to evaluate the results of deployment of Percutaneous Radiological Gastrostomy (PRG), which is a good alternative to Surgical Gastrostomy (SG), with transoral approach in cases where Percutaneous Endoscopic Gastrostomy (PEG) is contraindicated, difficult or unsuccessful, in patients with high risk of American Society of Anesthesiologists with four scores. In addition, we aimed to demonstrate the advantages of mushroom pull type catheters over push type gastrostomy catheters. METHODS: This retrospective study included a total of 40 patients (18 females and 22 males) aged 21-92 years who underwent PRG with the antegrade transoral approach. PRG was performed by retrograde passing through the esophagus or snaring the guidewire from the stomach and taking out of the anterior abdominal wall. Patients' demographic data, indications for PRG, procedural outcomes and complications were screened and recorded. RESULTS: PRG was performed in 39 of 40 patients included in the study. Technical success rate was 97.5%. Procedure-dependent major complications such as death, aspiration, colon perforation, and deep abscess were not observed. Aspiration occurred in the first patient during the first feeding on the day after the procedure. Major complication rate was 2.5%. The total minor complication rate was 17.5% in 7 patients; parastomal leakage in 2 patients (5%), skin rash and infection in 3 (7.5%) patients, minor bleeding in 2 (5%) patients with oropharynx cancer, minimal bleeding from the gastrostomy catheter 1 week after the procedure in 1 (2.5%) patient. None of the cases had buried buffer. Tube functionality was preserved in all patients without any damage. CONCLUSION: Mushroom tip (pull type) gastrostomy catheter is a safe treatment method for patients requiring prolonged feeding because of wide diameter, endurance, long staying opening duration, less excessive dilatation and parastomal leakage, and no need for gastropexy. Lower cost and easier access are advantageous for mushroom tip pull type catheters compared to push type gastrostomy catheters in our country. The less invasive PRG is an alternative option in patients who are difficult to administer PEG, are at high anesthesia risk and cannot be sedated. ADVANCES IN KNOWLEDGE: This article is valuable in terms of its contribution to develop an alternative radiological method for the deployment of gastrostomy tubes in medical difficult patients. This method has shortened the duration of the procedure and increased the success rate in patients with difficulty in transition from the stomach to the esophagus or with difficulty in the upper gastrointestinal tract. Mushroom tip catheters can be placed successfully by radiological methods.

Psychopathy, temperament, and character dimensions of personality as risk determinants of criminal recidivism in schizophrenia patients.

There is considerable evidence on the role of personality traits in the risk of criminal recidivism among schizophrenia patients, besides conventional risk factors. We evaluated the effects of psychopathy and biopsychosocial personality model on general criminal recidivism in schizophrenia patients. Ninety-four male DSM-5 diagnosed schizophrenia patients were recruited and classified into three groups according to the number of offenses since diagnosis: reoffenders (n = 32), Initial offenders (n = 31), and nonoffenders (n = 31). All subjects were evaluated by the Turkish versions of Psychopathy Checklist-Revised (PCL-R) and Temperament and Character Inventory-Revised (TCI-R). In Reoffenders, all subscale scores of PCL-R and Novelty seeking were the highest, while Self-directedness and Cooperativeness were the lowest. PCL-R Total, Factor 1 and Factor 2 positively correlated with Novelty Seeking, and negatively correlated with Harm Avoidance, Self-directedness, and Cooperativeness in offender patients. For criminal recidivism in offender patients, high PCL-R Total and Novelty Seeking, low Harm Avoidance, Self-directedness, and Cooperativeness, being unmarried, presence of childhood adversity, and younger age at the first offense were found to be significant predictors in univariate analyses; multivariate regression models revealed PCL-R Total and Persistence as the only significant predictors. These results suggest that certain dimensional personality evaluations combined with potential historical, clinical, and forensic risk factors can be employed in forensic settings to screen offender schizophrenia patients at an increased risk of recidivism and to take necessary precautions against further criminal behavior.

Prevalence and associated risk factors of coronary artery disease in patients with a zero coronary calcium score.

PURPOSE: A zero coronary calcium score (CCS) is not able to provide a definite exclusion for coronary artery disease (CAD). The goal of this study was to determine the prevalence and associated cardiovascular risk factors of CAD in patients with zero CCS. METHODS: Six hundred thirteen patients with zero CCS referred to coronary calcium score analysis (CCSA) and coronary computed tomography angiography (CCTA) with suspicion of CAD were included. The descriptive, univariate, and multivariate analyses were used to determine the prevalence and predictors of CAD presence. RESULTS: Among 613 patients, 17 patients (2.7%) have NCCP, and obstructive CAD was found in 3 patients (0.48%). Multivariate analysis revealed that male gender and older age (≥50 years) were significantly associated with the presence of noncalcified coronary plaques (NCCP) (p < 0.05). The receiver operating characteristic (ROC) curve analysis showed that the male gender and older age (≥50 years) model had 70.6% sensitivity and 84.2% specificity for predicting NCCP. CONCLUSION: A non-negligible portion of patients with zero CCS had CAD. Male gender and older age (≥50 years) were independently associated with NCCP. Due to the high specificity value (84.2%) and negative predictive value (99.0%) of the male gender and older age (≥50 years) model, selective use of CCTA is recommended in <50 years old female patients to avoid unnecessary radiation exposure.

Correlation of language lateralization with resting state hippocampal connectivity in temporal lobe epilepsy patients

Background/aim: The main purpose of this study is to evaluate the resting state hippocampal connectivity with language areas and to correlate them with laterality index calculations on single subject basis, hence to present hippocampal lateralization for language with rs-fMRI. Materials and methods: Task based and rs-fMRI data were gathered from a total of 45 subjects in 3T scanner. BrainVoyager QX, SPM, and CONN softwares were used for data analysis. LI score of each subject was calculated and converted into normalized LI score (nLI). Intrahemispheric rs-connectivity analysis was performed between hippocampus and Broca's regions on both sides. Correlation between these variables was measured with SPSS software. Results: Right-TLE patients were found to have highest whereas left-TLE group were found to have lowest mean LI scores. Regarding hippocampal-lingual networks; left intrahemispheric connectivity values showed strong positive correlation with nLI values in left, right-TLE patients and healthy controls (P = 0.035, 0.014, 0.047). There were no significant correlation between right intrahemispheric connectivity values and nLI scores in all groups. Conclusions: This study seems to depict the existence of resting state hippocampal-lingual functional network which correlates well with lateralization of language function in the left hemisphere in both temporal lobe epilepsy patients and healthy controls.

Should We Perform Transthoracic Trucut Lung Biopsies of Pleural-Based Lung Masses Under Ultrasound Guidance or Computed Tomography Guidance?

We aimed to emphasize which method should be prioritized by comparing the ultrasound and computed tomography (CT) guidance for percutaneous transthoracic biopsy of pleural-based lung lesions in terms of comorbidity, diagnostic success, time, and costs.Approximately 700 biopsy procedures performed between 2014 and 2018 were retrospectively reviewed. The files of these patients and picture archiving and communication system were scanned.Size and localization of the lesion, pathological diagnosis, comorbidity status, pneumothorax complications at the end of the procedure, and whether or not a thoracic tube was placed due to pneumothorax were recorded. Fisher exact test and Pearson χ test were used for statistical analysis.A total of 181 patients who underwent the pleural-based biopsy procedure, the subject of study, were included in the study. One hundred (55.2%) of the biopsy procedures of these patients were performed under the guidance of tomography, and 81 (44.8%) were performed under the guidance of ultrasound (US). Median size of the lesions is 38 mm (25%-75%, 33-55 mm). Pneumothorax complications were observed in 6 patients (6%) who had CT-guided procedures and 4 patients (4.9%) who had US-guided procedures. Of the patients who developed pneumothorax, 2.8% were inserted thoracic tubes owing to the complication. Diagnostic efficacy of our procedures is 99.8% in US-guided procedures and 97% in CT-guided transthoracic biopsy. The average duration of US-guided transthoracic biopsy procedures is 17 minutes, and the average duration of CT-guided biopsy procedures is 35 minutes.

Effectiveness of Superb Microvascular Imaging for the differentiation of intraductal breast lesions.

AIMS: The aim of this study was to compare the diagnostic performance of superb microvascular imaging (SMI) and power Doppler imaging (PDI) for the differentiation of intraductal breast lesions. MATERIALS AND METHODS: A total of 54 intraductal breast lesions (39 benign, 10 atypical, and 5 malignant) in 53 patients were examined using B-mode ultrasonography, PDI, and SMI. Vascularity grading, distribution of microvessels, and penetrating vessels were evaluated using each Doppler technique. The diagnostic performances of both methods were compared. RESULTS: SMI was more efficient in detecting flow signals than PDI (p=0.004). The highest diagnostic accuracy rates were achieved with SMI using vascular grading. When hypervascularity was used as a cut-off value to differentiate malignant and atypical lesions from benign lesions, the sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 66.6%, 80.7%, 66.6%, 80.7%, and 75.6%for PDI, and 86.6%, 76.9%, 68.4%, 90.9%, and 80.4% for SMI, respectively. CONCLUSIONS: SMI is more sensitive than PDI for detecting subtle blood flow in intraductal breast lesions with statistical significance. This novel and promising vascular imaging technique may be helpful in B-mode ultrasonography to distinguish intraductal breast lesions.

Advantages of b-mode ultrasound combined with strain elastography in differentiation of idiopathic granulomatous mastitis from malignant breast lesions

Background/aim: To evaluate the diagnostic performance of strain elastography (SE) combined with B-mode ultrasound in distinguishing between idiopathic granulomatous mastitis (IGM) and malignant breast lesions. Materials and methods: Seventy-seven malignant breast lesions and 36 IGM were assessed using B-mode ultrasound and SE. Ultrasonographic findings for all the breast lesions were classified based on the 2013 American College of Radiology Breast Imaging Reporting and Data System (BI-RADS-US), and the SE findings were evaluated based on the strain ratio and a five-point scale. The diagnostic performances of B-mode ultrasonography, SE, and the combination of both methods were compared. Results: Significant differences in strain ratio and elastography scores were found between IGM and malignant breast lesions. When the lesions were assessed with B-mode ultrasound alone, in order to distinguish between IGM and malignant breast lesions, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 94.8%, 66.7%, 85.9%, 85.7%, and 85.8%, respectively. However, when assessed with a combination of B-mode ultrasonography and SE, sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were 96.1%, 100%, 100%, 92.3%, and 97.3%, respectively. Conclusion: The combination of SE and B-mode ultrasound has better diagnostic performance in the differentiation of IGM and malignant breast lesions than B-mode ultrasonography alone.

Endovascular Treatment for Near Occlusion of the Internal Carotid Artery : 30-Day Outcome and Long-Term Follow-Up.

BACKGROUND: The treatment strategy and the correct incidence of near occlusion (NO) of the internal carotid artery (ICA) is still controversial. In routine radiological imaging NO can easily be misdiagnosed as complete occlusion and there is no consensus on the standard treatment strategy. PURPOSE: To present our perioperative and long-term follow-up results of ICA NO patients treated with carotid artery stenting (CAS). MATERIAL AND METHODS: Between 2004-2014 a total of 182 patients with ICA NO were evaluated for CAS. The study included 132 male (72.5 %) and 50 female (27.5 %) patients with a mean age of 70.2 years. Patients underwent a clinical neurological evaluation and radiological imaging of the carotid arteries before the CAS procedure. Of the patients 80 (44 %) were asymptomatic. The median clinical and carotid Doppler ultrasound (DUS) follow-up period was 64 months (range 18-124 months). RESULTS: In 182 patients CAS were performed, 4 patients (2.2 %) developed minor stroke, 2 patients (1.1 %) developed myocardial infarction but no major stroke or death occurred in the following 30-day period. Asymptomatic restenosis was detected in seven patients (3.8 %) in the follow-up period. CONCLUSION: With sufficient neurological evaluation during pretreatment and posttreatment periods and when the procedure is performed with technologically developed products by an experienced interventional team, CAS is beneficial in patients with ICA NO.

Diagnostic Performance of Superb Microvascular Imaging and Other Sonographic Modalities in the Assessment of Lateral Epicondylosis.

OBJECTIVES: The aim of this study was to compare the diagnostic performance of different sonographic modalities for diagnosing lateral epicondylosis. METHODS: A total of 50 symptomatic and 50 asymptomatic common extensor tendons in 44 patients with lateral epicondylosis, and 25 healthy participants were prospectively examined by B-mode sonography, color Doppler imaging, power Doppler imaging, Superb Microvascular Imaging (SMI; Toshiba Medical Systems Corporation, Tokyo, Japan), and strain elastography. We evaluated blood flow in common extensor tendons by using a grading system with color Doppler imaging, power Doppler imaging, and SMI. The diagnostic performance of the modalities was compared. RESULTS: When a cutoff value of hypoechogenicity was used for the mean strain ratio, the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy rates were 92.0%, 94%.0, 93.9%, 92.2%, and 93.0%, respectively. When a cutoff point of grade 1 was used, the sensitivity, specificity, PPV, NPV, and accuracy rates were 26.0%, 10.0%, 10.0%, 57.5%, and 63.0, for color Doppler imaging; 40.0%, 10.0%, 10.0%, 62.5%, and 70.0% for power Doppler imaging; and 84.0%, 94.0%, 93.0%, 85.5%, and 89.0% for SMI. When a cutoff value of 3.94 was used for the mean strain ratio, the sensitivity, specificity, PPV, NPV, and accuracy rates were 78.0%, 92.0%, 90.7%, 80.7%, and 85.0%, respectively. A statistically significant correlation was detected between SMI, strain elastography, and visual analog scale scores (P < .001). CONCLUSIONS: The combination of SMI and B-mode sonography was found to have excellent diagnostic performance for lateral epicondylosis. Neovascularzation in patients' tendons with lateral epicondylosis was identified much better with SMI compared to color or power Doppler imaging.
