RESUMEN

To evaluate the improvement of radiologist performance in detecting bone metastases at follow up low-dose computed tomography (CT) by using a temporal subtraction (TS) technique based on an advanced nonrigid image registration algorithm.Twelve patients with bone metastases (males, 5; females, 7; mean age, 64.8 ±â€Š7.6 years; range 51-81 years) and 12 control patients without bone metastases (males, 5; females, 7; mean age, 64.8 ±â€Š7.6 years; 51-81 years) were included, who underwent initial and follow-up CT examinations between December 2005 and July 2016. Initial CT images were registered to follow-up CT images by the algorithm, and TS images were created. Three radiologists independently assessed the bone metastases with and without the TS images. The reader averaged jackknife alternative free-response receiver operating characteristics figure of merit was used to compare the diagnostic accuracy.The reader-averaged values of the jackknife alternative free-response receiver operating characteristics figures of merit (θ) significantly improved from 0.687 for the readout without TS and 0.803 for the readout with TS (P value = .031. F statistic = 5.24). The changes in the absolute value of CT attenuations in true-positive lesions were significantly larger than those in false-negative lesions (P < .001). Using TS, segment-based sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of the readout with TS were 66.7%, 98.9%, 94.4%, 90.9%, and 94.8%, respectively.The TS images can significantly improve the radiologist's performance in the detection of bone metastases on low-dose and relatively thick-slice CT.

RESUMEN

OBJECTIVES: To evaluate the impact of systematic radiological review by breast specialist radiologist of malignant breast lesion imaging on the therapeutic management of patients. MATERIALS AND METHODS: Data collection was performed for patients with histopathologically proved breast cancer or suspicious breast lesion on imaging realized out of our institution. Patients underwent systematic mammary and axillary ultrasound, imaging review and if necessary complementary mammographic images. We analyzed the number of additional breast biopsies and axillary lymph node fine needle aspiration (FNA) with their histopathological results. We assessed their impact by comparing the final surgical treatment to the one planned before review. RESULTS: Two hundred and seventeen patients were included, with a total of 230 BIRADS 0, 4, 5 or 6 breast lesions. Seventy-six additional breast core biopsies were realized, leading to diagnose 43 additional BIRADS 6 lesions (24 infiltrative carcinomas, 9 DCIS and 10 atypical lesions) in 30 patients (13.82%). Thirty-five additional lymph node FNA were realized with 12 metastatic nodes and 3 false negative samples. Imaging review lead to change surgical treatment in 59 patients (27.19%, P<0.01) with modification in breast surgery in 37 patients, axillary surgery in 8 patients and both sites surgery in 12 patients. CONCLUSION: This study shows an impact of systematic radiological review by breast specialist radiologist in therapeutic management of patients treated for malignant breast lesion.

RESUMEN

BACKGROUND/AIM: The research objectives of this study were the estimation of the number of misdiagnosed breast lesions by non-expert-center-breast-radiologists (NEBR) and the investigation of the discordant rate (DR) calculated between initial and second opinion. Moreover, this study evaluated the impact of second opinion and the factors associated with DR. MATERIALS AND METHODS: A total of 399 patients were sent to our Tertiary Breast Cancer (BC) Center to perform fine needle aspiration/core needle biopsy (FNAC/CNB) after external examination. Lesions were reclassified according to Breast Imaging-Reporting and Data System (BI-RADS). External examinations were classified as breast-expert, not-breast-expert and physicians as expert-center-breast-radiologists (EBR), NEBR, and non-radiologists (NR). Personal/family history of breast cancer (BC), breast-density and presence of prior imaging were collected. RESULTS: DR was 74.3%. After second opinion, FNAC/CNB was proposed in 25.7% of cases and 2 additional cancers were detected. About 59.5% of unnecessary FNAC/CNB were avoided. Dense breast, no prior imaging examination and BC family-history were associated with higher DR (p-value<0.001); personal BC-history was associated in NEBR evaluations (p-value=0.0383). CONCLUSION: Second opinion review of outside examinations at expert BC Center may decrease unneeded biopsy, reducing health-care costs.

RESUMEN

OBJECTIVE: To determine burnout prevalence in Canadian radiology residency and identify contributing factors. MATERIALS AND METHODS: A prospective 57-item survey, including the 22-item Maslach Burnout Inventory-Health Sciences Survey, was sent to all Canadian radiology residents, with a total resident population of 359. The association between emotional exhaustion (EE), depersonalization (DP), and personal achievement (PA) scores with items in the survey was performed. Continuous data were evaluated using the Student t test for comparing the means between the 2 groups or the analysis of variance test for comparing the means between at least 3 groups. Spearman correlation coefficient was performed when evaluating ordinal categorical data. RESULTS: Response rate is 40.1% (n = 144); 50.7% of residents demonstrate high EE, 48.6% demonstrate high DP, and 35.9% demonstrate low PA. Being unhappy with residency and with radiology as a career is associated with burnout (P < .001). Age, sex, marital status, and children have no impact on burnout. More hours worked is associated with higher EE (P = .025) and DP (P = .004). In all, 47.2% residents experienced intimidation or harassment. Feeling unsupported by staff radiologists is associated with higher EE (P < .001), higher DP (P = .001), and lower PA (P = .008). In all, 45.1% of residents have poor work-life balance, and those residents demonstrate higher EE (P < .001), higher DP (P = .006), and lower PA (P = .01). In all, 25% of residents identify poor education-service balance in their residency, and those residents have higher EE (P < .001), higher DP (P = .042), and lower PA (P = .005). CONCLUSION: This study demonstrates significant burnout in Canadian radiology residents with major contributory factors identified.

RESUMEN

PURPOSE: Ultrasound-facilitated, catheter-directed, low-dose fibrinolysis (USAT) appears to provide promising results for the management of acute submassive pulmonary embolisms (ASMPEs) at tertiary care centers. This study assessed outcome measures at a community-based hospital systems and compared results to known studies. MATERIALS AND METHODS: This is a single-center, retrospective study assessing clinical outcomes of the EkoSonic Endovascular System intervention for ASMPEs performed by three surgical 3 subspecialties (interventional radiology, interventional cardiology, and vascular surgery) part of a pulmonary embolism response team (PERT). We reviewed 146 PERT activations from June 2013 to December 2017. Eighty-three patients with ASMPEs underwent USAT. RESULTS: Our study showed greater differences (P = .01) between baseline and follow-up pulmonary artery systolic pressures (20.9 ± 9.8 mm Hg [n = 14]) compared to the ULTIMA study (12.3 ± 10 mm Hg [n = 30]). Our length-of-stay measures were shorter (6.1 ± 5.1 [n = 83]; P = .0001) compared to the SEATTLE II study (8.8 ± 5.0 [n = 150]). Preprocedure transthoracic echocardiograms (TTEs) were performed for 54 (65%) of 83 patients. Postprocedure TTEs at 48 hours was performed for 52 (62%) of 83 patients. Use of TTEs before and after intervention did not change outcomes. Intracranial hemorrhage was not observed in our patient population. There was no difference in outcomes between the three subspecialties in our study. CONCLUSIONS: Use of USAT in a community-based hospital PERT has similar outcomes to tertiary care centers. Furthermore, similar outcomes were observed between the three subspecialties suggesting development of a comprehensive care team for management of ASMPEs.

RESUMEN

BACKGROUND: Radiology is an interface discipline. The radiologist must provide answers for various diagnostic questions in a short time by means of various examinations. The patient as well as the referring physician must be adequately and appropriately considered within a reasonable period, at the same time ensuring a high quality of examination with the lowest possible radiation exposure. MATERIALS AND METHODS: Over a 4-month period, a total of 102 patient interviews and 259 physician-patient interviews on patient satisfaction were randomly analyzed, specifically patient-physician communication and patient expectations and physician satisfaction and patient expectations. A psychologist carried out the questioning of the patients. Four radiologists evaluated their patient interaction using a standardized questionnaire, which was anonymized with regard to the patient data, based on a visual analogue scale. RESULTS: The patients displayed a high level of satisfaction with the discussion of radiologic findings. There was a positive correlation between the satisfaction with the discussion of findings and the clarity about the further steps necessary. Looking at the radiologists, there was also a positive correlation between the satisfaction with the patient interview and the fulfillment of the expectations; overall, physician's satisfaction with the interview was less positive than patient satisfaction. CONCLUSION: The radiologic patient is generally satisfied with the visit to the radiologist if a brief, understandable explanation of the disease is given, complemented by instructive next necessary steps.

RESUMEN

OBJECTIVE: Non-mass enhancement (NME) in breast MRI is the most common feature of ductal carcinoma in situ (DCIS). We sought to evaluate the interobserver variability and positive predictive value (PPV) for malignancy of NME descriptors using the fifth edition BI-RADS lexicon focusing on the newly introduced "clustered ring enhancement" pattern. MATERIALS AND METHODS: Breast MRIs of 129 patients who had undergone MRI-guided vacuum-assisted biopsy (VAB) in our institution were reviewed. Studies assessed as NME were classified according to the fifth edition BI-RADS lexicon by two breast radiologists. Consensus was reached by involving a third radiologist. Interobserver variability and PPV for malignancy were assessed. RESULTS: Seventy-two of 129 studies were assessed as NME. The disagreement rate in the first assessment step (mass vs. NME) was low at 9.3% (ĸ = 0.81, 95% confidence interval [CI] 0.71-0.91). The disagreement rate for distribution patterns was 23.6% (ĸ = 0.67, 95% CI 0.54-0.80) and 22.2% (ĸ = 0.69, 95% CI 0.56-0.81) for internal enhancement patterns. Clustered ring enhancement (PPV 53.85, p = 0.038) and segmental distribution (PPV 62.5%, p = 0.028) had the highest malignancy rates among internal enhancement and distribution patterns with a significant result; the combination of clustered ring enhancement and segmental distribution raised the malignancy rate by approximately 4% (PPV 66.67%, p = 0.049). CONCLUSION: There was a high agreement rate among readers when differentiating NME from mass lesions. The agreement rate was lower when assessing the distribution and internal enhancement pattern descriptors, but still substantial. The descriptors clustered ring enhancement and segmental distribution were significant predictors of malignancy. KEY POINTS: • Non-mass enhancement is a common morphological feature of non-invasive breast cancer (DCIS) in MRI. Differentiation between potentially malignant and benign changes may be very challenging. • Since clustered ring enhancement and segmental distribution are both significant predictors of malignancy, the awareness of this important finding, combined with high-quality image interpretation skills, may improve the tumor detection rate. • The combination of clustered ring enhancement and segmental distribution increases the positive predictive value for malignancy, which may be relevant for clinical practice.

RESUMEN

Ongoing discovery regarding the origin and treatment of vascular anomalies requires standardized nomenclature which itself must undergo iterative updating. This article introduces the 2018 International Society for the Study of Vascular Anomalies (ISSVA) classification, emphasizing the biologic basis of vascular anomalies, summarizing the key features of commonly encountered entities, and serving as a foundation for subsequent articles presented herein. Vascular tumors are discussed to highlight their distinction from vascular malformations which will receive greater attention with respect to management and technical considerations within the issue.

RESUMEN

BACKGROUND: Chest radiographs (CXR) are the most commonly used imaging techniques by various clinicians and radiologists. However, detecting lung lesions on CXR depends largely on the reader's experience level, so there have been several trials to overcome this problem using post-processing of CXR. We investigated the added value of bone suppression image (BSI) in detecting various subtle lung lesions on CXR with regard to reader's expertise. METHODS: We applied a software program to generate BSI in 1,600 patients in the emergency department. Of them, 80 patients with subtle lung lesions and 80 patients with negative finding on CXR were retrospectively selected based on the subtlety scores on CXR and CT findings. Ten readers independently rated their confidence in deciding the presence or absence of a lung lesion at each of 960 lung regions on the two separated imaging sessions: CXR alone vs. CXR with BSI. RESULTS: The additional use of BSI for all readers significantly increased the mean area under the curve (AUC) in detecting subtle lung lesions (0.663 vs. 0.706; P < 0.001). The less experienced readers were, the more AUC differences increased: 0.067 (P < 0.001) for junior radiology residents; 0.064 (P < 0.001) for non-radiology clinicians; 0.044 (P < 0.001) for senior radiology residents; and 0.019 (P = 0.041) for chest radiologists. The additional use of BSI significantly increased the mean confidence regarding the presence or absence of lung lesions for 213 positive lung regions (2.083 vs. 2.357; P < 0.001) and for 747 negative regions (1.217 vs. 1.195; P = 0.008). CONCLUSION: The use of BSI increases diagnostic performance and confidence, regardless of reader's expertise, reduces the impact of reader's expertise and can be helpful for less experienced clinicians and residents in the detection of subtle lung lesions.

RESUMEN

This is a condensed summary of an international multisociety statement on ethics of artificial intelligence (AI) in radiology produced by the ACR, European Society of Radiology, RSNA, Society for Imaging Informatics in Medicine, European Society of Medical Imaging Informatics, Canadian Association of Radiologists, and American Association of Physicists in Medicine. AI has great potential to increase efficiency and accuracy throughout radiology, but it also carries inherent pitfalls and biases. Widespread use of AI-based intelligent and autonomous systems in radiology can increase the risk of systemic errors with high consequence and highlights complex ethical and societal issues. Currently, there is little experience using AI for patient care in diverse clinical settings. Extensive research is needed to understand how to best deploy AI in clinical practice. This statement highlights our consensus that ethical use of AI in radiology should promote well-being, minimize harm, and ensure that the benefits and harms are distributed among stakeholders in a just manner. We believe AI should respect human rights and freedoms, including dignity and privacy. It should be designed for maximum transparency and dependability. Ultimate responsibility and accountability for AI remains with its human designers and operators for the foreseeable future. The radiology community should start now to develop codes of ethics and practice for AI that promote any use that helps patients and the common good and should block use of radiology data and algorithms for financial gain without those two attributes.

RESUMEN

BACKGROUND: Rib fractures are common and potentially life-threatening. Fast and correct detection as well as comprehensive visual overview of rib fractures are of clinical and forensic importance. This study compared two computed tomography (CT) reformation methods, curved planar reformation (CPR) with conventional multiplanar reformation (MPR), regarding detection of rib fractures in different readers. METHODS: Twelve postmortem CT datasets were retrospectively assessed for rib fractures using CPR and MPR. After defining the gold-standard regarding side, level, localization, and quantity of fractures, four reader groups per two readers consisting of radiologists, trauma surgeons, forensic pathologists, and laypersons, were evaluated for sensitivity, proportion of false positives, time to fracture detection, and subjective preference. RESULTS: Overall sensitivity for fracture detection did not vary significantly between both methods. However, it was significantly higher in trauma surgeons and laypersons when reading CPR compared to MPR (70.7% vs. 62.0%, p=0.038 and 33.7% vs. 22.1%, p=0.003 respectively). It was significantly lower in radiologists (63.8% vs. 76.8%, p=0.001). Forensic pathologists performed similarly with both methods (53.6% vs. 56.5%, p=0.549). All non-radiologists preferred the use of CPR (75%). All readers found CPR to provide better visual overview (100%). CONCLUSION: CPR may increase rib fracture detection rates of non-radiologists (i.e. trauma surgeons and laypersons) and provides a better visual overview. However, radiologists achieve higher fracture detection rates when allowed to work with the software tools they are more experienced with. The overall sensitivity was improvable and better visualization methods are warranted in order to avoid misdiagnosis and medicolegal errors regarding rib fracture detection.

RESUMEN

OBJECTIVE: We proposed to determine whether the performance of inexperienced radiologists in determining extramural vascular invasion (EMVI) in rectal cancer on MRI can be promoted by means of targeted training. METHODS: 230 rectal cancer patients who underwent pre-operative chemoradiotherapy were included. Pre-therapy and post-therapy MR images and pathology EMVI evaluation were available for cases. 230 cases were randomly divided into 150 training cases and 80 testing cases, including 40 testing case A and 40 testing case B. Four radiologists were included for MRI EMVI evaluation, who were divided into targeted training group and non-targeted training group. The two groups evaluated testing case A at baseline, 3 month and 6 month, evaluated testing case B at 6 month. The main outcome was agreement with expert-reference for pre-therapy and post-therapy evaluation, the other outcome was accuracy with pathology for post-therapy evaluation. RESULTS: After 6 months of training, targeted training group showed statistically higher agreement with expert-reference than non-targeted training group for both pre-therapy and post-therapy MRI EMVI evaluation of testing case A and testing case B, all p < 0.05. Targeted training group also showed significantly higher accuracy with pathology than non-targeted training group for post-therapy evaluation of testing case A and testing case B after 6 months of training, all p < 0.05. CONCLUSION: The diagnostic performance for MRI EMVI evaluation could be promoted by targeted training for inexperienced radiologist. ADVANCES IN KNOWLEDGE: This study provided the first evidence that after 6 month targeted training, inexperienced radiologists demonstrated improved diagnostic performance, with a 20% increase in agreement with expert-reference for both pre-therapy and post-therapy MRI EMVI evaluation and also a 20% increase in or accuracy with pathology for post-therapy evaluation, while inexperienced radiologists could not gain obvious improvement in MRI EMVI evaluation through the same period of regular clinical practice. It indicated that targeted training may be necessary for helping inexperienced radiologist to acquire adequate experience for the MRI EMVI evaluation of rectal cancer, especially for radiologist who works in a medical unit where MRI EMVI diagnosis is uncommon.
