RESUMEN
PURPOSE: The aim of this study was to evaluate the diaphragm thickness in patients with obstructive sleep apnea syndrome (OSAS). METHODS: This prospective study included patients who underwent polysomnography evaluation for the first time with a clinical suspicion of OSAS. All patients underwent polysomnographic evaluation with a 55-channel Alice 6 computerized system (Respironics; Philips, IL). Diaphragm thickness was measured as the distance between the peritoneum and the pleura using electronic calipers with a 7-12-MHz linear probe (PHILIPS EPIQ 5G). RESULTS: A total of 108 patients (67 males, 41 females) were enrolled in the current study. The mean age of the patients was 48.92 ± 11.47 years. The diaphragm thicknesses were significantly higher in OSAS patients both at end-inspirium and end-expirium compared with the normal group (p < 0.05). No significant difference was observed regarding the change level and thickening ratio (%) (p > 0.05). When the patients were allocated into OSAS subtypes; diaphragm thicknesses at the end of inspirium and expirium on both sides were significantly higher in the severe OSAS group and OSAS+OHS group compared with the other groups of normal, mild OSAS, and moderate OSAS subgroups (p < 0.05 for all). There was no significant difference between the groups regarding the thickening ratio (p > 0.05 for all). There was a positive correlation between the severity of OSAS and diaphragm thickness. CONCLUSION: Diaphragm thickness seems to be increased in OSAS patients and the thickness correlates with the severity of OSAS. However, the thickness ratio of OSAS patients does not differ from that of normal subjects.

OBJECTIVE: The aim of this study was to investigate whether the use of combination quantitative metrics (mamillopontine distance [MPD], pontomesencephalic angle, and mesencephalon anterior-posterior/medial-lateral diameter ratios) with qualitative signs (dural enhancement, subdural collections/hematoma, venous engorgement, pituitary gland enlargements, and tonsillar herniations) provides a more accurate diagnosis of intracranial hypotension (IH). METHODS: The quantitative metrics and qualitative signs of 34 patients and 34 control subjects were assessed by 2 independent observers. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic performance of quantitative metrics and qualitative signs, and for the diagnosis of IH, optimum cutoff values of quantitative metrics were found with ROC analysis. Combined ROC curve was measured for the quantitative metrics, and qualitative signs combinations in determining diagnostic accuracy and sensitivity, specificity, and positive and negative predictive values were found, and the best model combination was formed. RESULTS: Whereas MPD and pontomesencephalic angle were significantly lower in patients with IH when compared with the control group (P < 0.001), mesencephalon anterior-posterior/medial-lateral diameter ratio was significantly higher (P < 0.001). For qualitative signs, the highest individual distinctive power was dural enhancement with area under the ROC curve (AUC) of 0.838. For quantitative metrics, the highest individual distinctive power was MPD with AUC of 0.947. The best accuracy in the diagnosis of IH was obtained by combination of dural enhancement, venous engorgement, and MPD with an AUC of 1.00. CONCLUSIONS: This study showed that the combined use of dural enhancement, venous engorgement, and MPD had diagnostic accuracy of 100 % for the diagnosis of IH. Therefore, a more accurate IH diagnosis can be provided with combination of quantitative metrics with qualitative signs.

PURPOSE: Congenital and acquired pathologies of the seminal vesicles (SV) are rare diseases. The diagnosis of SV anomalies is frequently delayed or wrong due to the rarity of these diseases and the lack of adequate evaluation of SV pathology. For this reason, we aimed to comprehensively evaluate SV pathologies and accompanying genitourinary system abnormalities. MATERIALS AND METHODS: Between March 2012 and December 2015, 1455 male patients with different provisional diagnosis underwent MRI. Congenital and acquired pathology of the SV was identified in 42 of these patients. The patients were categorized according to their SV pathologies. The patients were analyzed in terms of genitourinary system findings associated with SV pathologies. RESULTS: SV pathologies were accompanied by other genitourinary system findings. Congenital SV pathologies were bilateral or predominantly in the left SV. Patients with bilateral SV hypoplasia were diagnosed at an earlier age compared to patients with unilateral SV agenesis. There was a significant association between abnormal signal intensity in the SV and benign prostate hypertrophy (BPH) and patient age. CONCLUSION: SV pathologies are rare diseases of the genitourinary system. The association between seminal vesicle pathology and other genitourinary system diseases requires complete genitourinary system evaluation that includes the seminal vesicles.

BACKGROUND: Liver size can be influenced by various factors, including malignant diseases, infective processes, and anthropometric variations among individuals from different geographical locations and races. Therefore, the exact definition of hepatomegaly in the ultrasonographic measurement of liver size is controversial. Moreover, the majority of studies regarding the study of liver size are not community-based. AIMS: The aim of this study is to establish a range of normal liver sizes by ultrasonography with respect to age and sex in healthy individuals and to identify factors affecting liver size. STUDY DESIGN: This was a prospective, community-based study. METHODS: Liver size was measured ultrasonographically from the midclavicular line in 822 individuals, of which 49.3% (n = 405) were male and 51.7% (n = 417) were female. Following physical examination, all participants provided blood samples. Height, weight, and waist circumference were recorded. The mean liver length was calculated for males, females, and for the whole study group. It was also determined whether there was an association between liver size and age, weight, height, body mass index (BMI), body surface area, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) enzyme levels. Results: The mean liver length was significantly different between males (150.04 ± 14.84) and females (147.57 ± 18.32, P = 0.034). Weight and BMI were the most strongly associated with liver size. There was a significant difference between liver size in individuals with normal and elevated levels of AST and ALT enzymes (P < 0.01). CONCLUSION: In a northern Anatolian Turkish population, liver size was greater among males than females. In light of these data, we believe our study may serve as a reference source for the evaluation of liver size.

PURPOSE: Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease can result in mortality varying from 3.0% to 50.0%. In this study, we wished to discuss computed tomography (CT) findings together with clinical and laboratory findings in patients who had disease-related neurological signs. MATERIALS AND METHODS: The study included patients who were diagnosed with CCHF. Seventeen patients that had neurological signs were enrolled as the patient group. As a control group, 40 patients diagnosed with CCHF and did not have neurological signs were enrolled. Patients who had neurological signs were examined with brain CT. Radiological and clinical findings of both groups were compared. RESULTS: There were pathological findings in three patients while brain CT's of 14 patients were evaluated as normal. Blood urea nitrogen, lactate dehydrogenase, creatine kinase, total bilirubin, neutrophil, activated partial thromboplastin time, and C-reactive protein levels were significantly higher in the group with neurological signs whereas platelet count and calcium levels were significantly lower in this group. Six of 57 patients died during the follow-up period. Six patients who died were in the group, in which central nervous system (CNS) imaging study was performed. CONCLUSION: As the presence of CNS signs is a bad prognostic indicator in CCHF, they should be investigated carefully.

A 26-year-old female patient with Type 1 Gaucher's disease (GD) was admitted to our clinic with complaints of stomachache and signs of anemia. The patient underwent ultrasonography (US), computerised tomography (CT), and magnetic resonance imaging (MRI) scan. Imaging studies revealed massive hepatosplenomegaly, choledocolithiasis, and six nodules in the spleen with a mean size of 14 mm. The nodules appeared hyperechoic, hypoechoic, and of mixed echogenicity on the US and hypodense on the CT. While the nodules were observed to be iso-hypointense in T1-weighted (T1WI) images, they appeared to be hyperintense in the T2-weighted (T2WI) images. There were no diffusion restrictions in these nodules that appeared on the diffusion-weighted magnetic resonance imaging (DWI). A nodule located at the lower pole was observed to be hypointense in the T2WI images. The nodule located at the lower pole, which appeared hypointense in T2WI series, had restricted diffusion upon DWI. In this study, we aimed to present the properties of splenic GD nodules using US, CT, and conventional MRI, together with DWI. This case report is the first to apply US, CT, and conventional MRI, together with DWI, to the splenic nodules associated with Gaucher's disease.
RESUMEN
PURPOSE: To evaluate cisterna chyli (CC) diameter with magnetic resonance imaging (MRI) in patients with chronic kidney disease (CKD). MATERIALS AND METHODS: The study included 71 patients with CKD and 68 healthy controls. In both groups, the largest transverse diameter of CC was measured in axial heavily T2 -weighted images using a 1.5T MRI. The diameter of the CC in the CKD patients and control group were compared, and the correlations between the CKD, glomerular filtration rate (GFR), and stage of CKD were investigated. The CC diameters were compared between/among groups with independent sample t-test or one-way analysis of variance (ANOVA). A receiver operating characteristic (ROC) curve was constructed for CC diameter to determine the effectiveness of various cutoff points for the presence of CKD. The Pearson correlation coefficient was used to examine correlation between CC diameter and GFR. Multivariate logistic regression models were implemented in order to examine to determine relation among selected variables and study group. RESULTS: The average CC diameter was 5.68 ± 2.55 mm in the CKD group, and 3.18 ± 2.24 mm in control group (P < 0.001). The CC diameter showed an increase with more severe stages of the disease (P < 0.001). There was a significant negative correlation between CC diameter and GFR (r -0.447, P < 0.001). Based on multivariate analysis, it was determined that the only factor associated with severity of disease was CC diameter (odds ratio: 1.636, 95% confidence interval: 1.314-2.037, P < 0.0001). Based on ROC analysis, the optimal CC diameter cutoff value for detecting CKD was 4.5 mm, with sensitivity and specificity values of 0.704 and 0.824, respectively. CONCLUSION: CC diameter is observed to be larger in patients with CKD than in the normal population. Additionally, CC diameter increased with more severe stages of CKD. According to our results, CC diameter might be used as an MRI marker to indicate the presence and severity of CKD. J. MAGN. RESON. IMAGING 2016;44:890-896.

PURPOSE: Crimean-Congo hemorrhagic fever (CCHF) is a viral tick-borne illness. Although its etiopathogenesis is not clearly understood, it is known to be a Nairovirus. We aimed to examine the viral effects of intense systemic inflammation and vascular damage on the pulmonary vascular beds and lung tissues. METHODS: A total of 45 patients who were diagnosed with CCHF were considered for this retrospective study. In this patient group, those whose lungs had been visualized via thoracic computer tomography (CT) were entered into the study. Diameters of the pulmonary trunk, main pulmonary arteries, atria, and ventricles were measured. Study group measurements were compared with the control group, which included patients with normal thoracic CT. RESULTS: Overall, 90 patients were enrolled in the study, with 45 patients in the study group and 45 in the control group. In the study group, the man-to-woman balance was 3/2. The average age in the study group was 54.07 ± 17.91 years. In comparing the average diameters of pulmonary arteries in the study and control groups, the study group's average pulmonary artery diameter was significantly larger than the control group (p < 0.001). CONCLUSIONS: The increase in diameters of the pulmonary trunks and main pulmonary arteries due to CCHF was first shown in this current study. Moreover, due to our findings, it should be noted that with the rise in pulmonary artery diameter in CCHF, pulmonary hypertension can appear acutely, and this condition can be significantly alter clinical course and follow-up of the viral illness.

BACKGROUND: Identifying the craniofacial abnormalities that cause snoring and the narrowest area of the upper airway creating obstructions can help to determine the proper method of treatment. AIM: To identify the factors that can cause snoring and the areas of the airway that are the most likely to collapse with upper airway imaging. MATERIAL AND METHODS: Axial pharynx examinations with CT (computerized tomography) and magnetic resonance imaging (MRI) were performed to 38 patients complaining of snoring and 12 patients who did not complain of snoring. The narrowest areas of nasopharynx, hypophraynx, oropharynx, bilateral para-pharyngeal fat pad and para-pharyngeal muscle thickness were measured. RESULTS: In snoring patients, the narrowest part of the upper airway was the retro-palatal region in the oropharynx, as measured with both imaging methods. When patients with and without snoring were compared, the former that a higher body mass index and neck diameter and a narrower oropharynx area. In dynamic examinations, we determined that as para-pharyngeal muscle thickness increased, medial-lateral airway diameter and the oropharynx area decreased. CONCLUSIONS: The narrowest section of the airway is the retro-palatal region of the oropharynx, measured both with CT and MRI.

Tracheal bronchus is a rarely seen congenital anomaly generally originating from the right lateral wall of the trachea and approximately 2 cm above the carina. It was firstly defined by Sandifort in 1785 and its frequency of incidence in normal population changes between 0.1% and 2%. There are two types called ''Supernumerary'' and ''Displaced''. It is a rarely seen kind of tracheal anomaly although fairly well defined. The cases accompanied by lung cancer are seen more rarely. Nine cases of this association were reported in literature and tracheal bronchus-lung cancer association whose pathological result is undifferentiated large-cell carcinoma has not been stated so far. We present a 75 years old male patient as possibly the first case having tracheal bronchus and large-cell carcinoma association in literature.

BACKGROUND: Ankylosing spondylitis (AS) may present with extra-articular involvement in the lungs. We aimed to evaluate the abnormal pulmonary multidetector computed tomography findings of patients with AS and compare them with the clinical symptoms, duration of illness, laboratory results and pulmonary function tests (PFT). MATERIAL/METHODS: We evaluated the chest multidetector computed tomography (MDCT) findings of 41 patients with ankylosing spondylitis (AS) and compared them with pulmonary function test (PFT) results, demographic characteristics, duration of illness and laboratory findings that we were able to obtain. RESULTS: The most common abnormalities were nodules, peribronchial thickening, pleural thickening and bronchiectasis. Abnormalities occurred in 96.87% of patients in the early AS group and 77.8% of patients in the late AS group. Patients with early AS included asymptomatic individuals with normal PFT results and abnormal MDCT findings. CONCLUSIONS: The use of MDCT in AS patients may be beneficial for the evaluation of pulmonary disease, even in asymptomatic patients without any PFT abnormalities and those in the early stages of the disease.
RESUMEN
PURPOSE: Intracranial hypertension (IH) is a neurological disease that is characterized by increased intracranial pressure. Idiopathic intracranial hypertension (IIH) is characterized by an increase in intracranial pressure without an underlying neuroradiological cause (1-3). The IH that is associated with a reason such as a mass, hydrocephalus, or drug use, is referred to as secondary intracranial hypertension (SIH). We aimed to detect determine whether the increased intracranial pressure causes a change in the diffusion values of brain in the diffusion MRI images. METHODS: The study includes 24 consecutive patients that were diagnosed with IIH and 18 consecutive patients that were diagnosed with secondary intracranial hypertension (SIH). The control group included 24 patients. Measurement of apparent diffusion coefficient (ADC) was performed using DWI sections obtained from subcortical white matter and the cortex of the frontal lobe in the basal ganglia plane, caudate nucleus head, thalamus, the posterior leg of the internal capsule, corpus callosum splenium; in the centrum semiovale plane, from the central white matter region. with 1.5T MRI using b=500s/mm2 and b=1000s/mm2 values both in patients and control groups. Mean ADC values were compared between IIH, SIH patients and control groups. RESULTS: The ADC values from the head of the caudate nucleus and the cortex were significantly higher in the IIH group, compared to the control group. When the ADC values of the SIH and control groups were compared, it was found that some of the ADC measurements (subcortical white matter, cortex and semioval center) were significantly different. The comparison of the IIH and the SIH groups revealed that the ADC measurements central white matter in the centrum semiovale, the subcortical white matter and the posterior leg of the internal capsule were significantly different. Conclusions: We have found increased diffusion IIH and SIH patients, which supports the development of brain edema. Even though the mechanism of the brain edema in IIH are not entirely clear, it is thought that the mechanism is different from the brain edema caused by a mass or a sinus thrombosis.
RESUMEN
BACKGROUND: Pelvic floor dysfunction is characterized by incomplete fecal defecation, affecting quality of life in a negative way. Magnetic resonance defecography (MRD) is a useful examination that is ionizing radiation-free and easily reproducible, and which provides anatomical and functional details that are obtainable through multiplanar and dynamic examinations. We aimed to detect pathology using MRD in patients with suspected pelvic floor dysfunction and determine its cause. METHODS: MRD was performed in 79 individuals. Dynamic images were obtained at rest, straining, and during defecation. Pelvic hiatus mediolateral diameters were compared between groups. RESULTS: Defecation phase provided significantly more accurate results than the straining phase for determining the existence and severity of pathology. Conclusions: The defecation phase is the most accurate phase for identifying the existence and severity of pathology. As the pelvic hiatus mediolateral diameter is thought to be an important factor in triggering pelvic dysfunction.
RESUMEN
OBJECTIVE: It has been advocated that a reduced injection volume with highly concentrated (1 M) contrast material can produce a sharper bolus peak and an increased intravascular first-pass gadolinium concentration when compared with the use of a lower concentration (0.5 M). A higher concentration would also cause a reduction in dose. The purpose of our study was to test the use of a low dose (0.05 mmol/kg) of gadobutrol in magnetic resonance renography and angiography and compare the findings with a dose of 0.1 mmol/kg. MATERIALS AND METHODS: One-hundred-thirty-four patients referred for magnetic resonance angiography for suspected renovascular disease participated in the study. Contrast enhanced MR renography and angiography were performed after administration of a bolus of 0.1 mmol/kg or 0.05 mmol/kg gadobutrol in randomized patients. The relative signal intensity-time curves of the aorta, peripheral cortex and parenchyma, were obtained. Two radiologists evaluated the angiographic images and evaluated the quality of angiography. RESULTS: The signal intensity with a low dose of gadobutrol was significantly lower in early phases, in the peripheral cortex (for 36, 54, 72 and 90 seconds), the parenchyma (for 36, 54, 72 seconds) and the aorta (for 18, 36, 54, 72 seconds). The decreases in the early phase obtained with a low dose of gadobutrol caused blunter time intensity curves. The difference in the quality scores of the readers for the angiographic images for the use of the two different doses was not statistically significant (p > 0.05). CONCLUSION: A lower dose of gadobutrol can be used for MR renal angiography, but for MR renography the normal dose should be used.

Primary vascular leiomyosarcoma is a rare tumor, which arises mainly from the inferior vena cava. Clinical signs are non-specific. Systemic metastasis occurs in the late stage. Imaging with color Doppler ultrasonography, contrast-enhanced computed tomography, or magnetic resonance imaging can significantly contribute to the diagnosis. We present a case of leiomyosarcoma of the inferior vena cava that extended into the right renal vein and the right iliac vein, as it is a rare case and emphasize the significance of the imaging methods in its diagnosis.

Joubert syndrome is a rare disorder characterized by hypotonia, ataxia, episodic hyperpnoea, psychomotor delay, abnormal ocular movements, and molar tooth sign on magnetic resonance imaging (MRI). This syndrome is inherited as an autosomal recessive trait, but the molecular basis and specific chromosomal locus have not yet been identified. MRI features are the most important diagnostic criteria. Molar tooth sign was previously described in Joubert syndrome and was found in 85% of patients with Joubert syndrome. Many authors now claim that this finding can be present in other syndromes, including Dekaban-Arima, Senior-Löken, COACH, and Varadi-Papp. We present a 7-month-old girl with Joubert syndrome in whom MRI showed the typical features of this condition. She also had polydactyly, atrial septal defect, and persistent left superior vena cava.

PURPOSE: Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic viral disease with high mortality. The agent causing CCHF is a Nairovirus. The virus is typically transmitted to humans through tick bites. CCHF is a life-threatening disease observed endemically over a wide geographical regions in the world and a little known about pulmonary findings in CCHF patients. METHODS: The patients that were admitted and diagnosed with CCHF between April 2010 and September 2015 were examined. Patients' medical records were then evaluated retrospectively. Patients who underwent thorax CT evaluation based on the clinical findings at the time of admission and/or during the hospital stay were included in the study. Patients' laboratory test results and thorax CT findings for respiratory assessment along with demographic characteristics. RESULTS: Forty patients diagnosed with CCHF that underwent thorax CT based on their indications were included in the study. Twenty-seven patients (62.5 %) were male with a mean age of 55.22 ± 19.84 years. According to these results, the three most common thorax CT findings were parenchymal infiltration [32 patients (80 %)], pleural effusion [31 patients (77.5 %)], and alveolar infiltration [28 patients (70 %)]. Moreover, we determined that the most frequently seen radiological findings often occurred bilaterally. CONCLUSIONS: There is still not enough information regarding this life-threatening disease. We also would like to emphasize that both direct radiography and thorax CT are highly successful in detecting frequently encountered radiological findings such as pleural effusion, alveolar hemorrhage, and parenchymal infiltration that indicate pulmonary involvement.
RESUMEN
Intraductal papillary mucinous neoplasia (IPMN) is one of the cystic neoplasias of the pancreas. The imaging findings provide that these tumors are differentiated from the other cystic lesions of the pancreas, especially from the chronic pancreatitis, where the treatment protocol is completely different. Therefore, the correct diagnosis and classification of the IPMN ensures that the patient receives the correct approach and the appropriate surgery, if necessary. The purpose of this study is to emphasize the imaging findings of the different types of the IPMN and the changes in the management protocol of the patients according to these radiological findings.
RESUMEN
OBJECTIVE: Crimean-Congo hemorrhagic fever (CCHF) is a widely seen, fatal disease and is endemic to some countries. It affects many organs in the abdomen. Comprehensive radiological study of CCHF is quite rare. This study will use multiple detector computed tomography (MDCT) to investigate if there is a relationship between clinical laboratory measurements and abdominal findings in CCHF and discuss our findings in the light of the literature. MATERIALS AND METHODS: We retrospectively evaluated the medical records of 443 patients diagnosed with CCHF in our hospital between April 1, 2008 and September 30, 2014. Fifty-one patients had undergone abdominal MDCT examination. RESULTS: The most common findings seen in abdominal MDCT were intra-abdominal free fluid and hepatomegaly. Gallbladder wall thickening, heterogeneity in mesenteric, omental fatty tissue, and splenomegaly were other common findings. Subcutaneous fat tissue edema, intramuscular hemorrhage, duodenal wall thickening, colon wall thickening, pancreatitis, and acute renal failure were among the rare findings seen in abdominal MDCT. Comparison of these findings to the clinical laboratory parameters showed a strong relationship between intra-abdominal free fluid and platelet count. CONCLUSION: Our study is the first comprehensive study on abdominal MDCT findings of CCHF. We detected a strong relationship between patients' platelet count and abdominal free liquid. Therefore, it should be kept in mind that abdominal free fluid can be among clinical manifestations in patients with platelet counts ≤50000 and that this manifestation can become aggravated.
