Our study aims to evaluate the ability of MRI in assessing treatment response comparing an objective mrTRG score and a subjective Likert score, with a focus on the ability to predict pathologic complete response (pCR). Methods: Post-treatment MRI studies were retrospectively reviewed for 170 consecutive cases of histopathologically proven rectal cancer after receiving neoadjuvant chemoradiation and prior to surgery by two oncoradiologists blinded to the eventual postoperative histopathology findings. An objective (mrTRG) and a subjective Likert score were assigned to all the cases. Receiver operating characteristic curves were constructed to determine the ability of Likert scale and mrTRG to predict pCR, with postoperative histopathology being the gold standard. The optimal cutoff points on the scale of 1 to 5 were obtained for mrTRG and Likert scale with the greatest sum of sensitivity and specificity using the Youden Index. Results: The most accurate cutoff point for the mrTRG to predict complete response was 2.5 (using Youden index), with a sensitivity of 69.2%, specificity of 69.6%, positive predictive value (PPV) of 85.6%, negative predictive value (NPV) of 46.4%, and accuracy of 69.3%. The most accurate cutoff for the Likert scale to predict complete response was 3.5, with a sensitivity of 47.5%, specificity of 89.1%, PPV of 91.9%, NPV of 39.4%, and accuracy of 59%. mrTRG had a lower cutoff and was more accurate in predicting pCR compared to Likert score. Conclusion: An objective mrTRG was more accurate than a subjective Likert scale to predict complete response in our study.","PeriodicalId":51597,"journal":{"name":"Indian Journal of Radiology and Imaging","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135877945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to report the results of a survey on factors affecting the work–life balance of interventional radiologists (IR). Material: The survey consisted of 30 questions focusing on work, family, and personal health. The questionnaire addressed knowledge, attitude, and practice. This online survey was sent to IRs across the globe and the responses were analyzed by three IRs (SH, SNK, SK). Results: On univariate analysis, the major risk factors for burnout were presence of weekend duties (n = 91, 98.9%, p = 0.02), absence of support group at workplace (n = 36, 39.1%, p = 0.005), having tough time with administration (n = 61, 66.3%, p = 0.001), not able to spend quality time on family (n = 30, 32.6%, p = 0.035), and inability to find time to do things that one enjoys (n = 53, 57.6%, p = 0.0002). However, multivariate analysis revealed that those having tough time with administration (odds ratio = 2.77 [95% confidence interval [CI]: 1.12–6.48], p = 0.02) and those who could not find time to do things one enjoys (odds ratio = 4.79 [95% CI: 1.42–16.1], p = 0.01) were only statistically significant. Conclusion: Burnout is common among IRs and is considered a significant issue that needs to be addressed. Teamwork, a support structure for major events, healthy lifestyle, and dedicated time for family may combat the burnout.","PeriodicalId":51597,"journal":{"name":"Indian Journal of Radiology and Imaging","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135878286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They were questioned on their demographics, frequency of on call, fatigue experienced on call, and preferred information resources and reasons for choosing them. <b>Results</b>  A total of 286 residents participated in the survey. All residents had used the Internet radiology resources during on-call duties. The most preferred resource material was Radiopaedia followed by Radiology Assistant. IMAIOS e-Anatomy was the most preferred anatomy resource. There was significant ( <i>p</i>  < 0.05) difference in relation to the use of closed edit peer-reviewed literature among the two batches with it being used almost exclusively by third year residents. In the artificial intelligence-aided ChatGPT section, 61.8% had used the software at least once while being on call, of them 57.6% responded that the information was inaccurate, 67.2% responded that the information was insufficient to aid in diagnosis, 100% felt that the lack of images in the software made it an unlikely resource that would be used by them in the future, and 85.8% agreed that they would use it for providing reporting templates in the future.

The infiltration predominantly involves liver, spleen, lymph nodes, and central nervous system. Neuroimaging features on magnetic resonance imaging are highly nonspecific and variable.
