We aimed to compare chest CT findings in patients with FB by underlying disease: rheumatoid arthritis (RA), Other connective tissue diseases (CTDs), and those without CTD. Methods A retrospective cohort of patients with pathologically-proven follicular bronchiolitis was classified into three groups: RA (n = 9), Other CTDs (n = 6), and non-CTD (n = 13). Chest CT were reviewed for findings including tree-in-bud nodules and air trapping (small airway disease), ground glass opacities, fibrosis, and bronchiectasis. Chi-square test was performed to evaluate the frequency differences across three groups. Fisher's exact test was performed to compare RA group and non-RA group. Results In all patients, the most common CT finding was bronchiectasis (17/28, 61 %), followed by small airway disease features (14/28, 50.0 %), fibrosis (13/28, 46.4 %), and ground glass opacities (7/28, 25.0 %). In three-group comparison (RA vs. Other CTD vs. non-CTD), small airway disease was significantly more prevalent in other CTD (3/6, 50.0 %) and non-CTD (10/13, 76.9 %) groups compared to the RA group (1/9, 11.1 %) (p = 0.01). In two-group analysis (RA vs. non-RA), fibrosis (7/9, 77.8 % vs. 6/19, 31.6 %; p = 0.041) and bronchiectasis (8/9, 88.9 % vs. 9/19, 47.4 %; p = 0.049) were significantly more common in the RA group compared to non-RA patients. Conclusion Chest CT findings of FB vary significantly depending on the underlying disease. Small airway disease features predominate in non-RA patients, while patients with RA and FB more frequently show fibrosis and bronchiectasis, likely reflecting coexistent pulmonary manifestations of RA. Recognizing these imaging patterns may improve diagnostic accuracy and inform appropriate management.","PeriodicalId":93969,"journal":{"name":"Current problems in diagnostic radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144719275","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}

Existing reports were evaluated for the description of emphysema phenotype, severity, and location, as well as the presence of associated findings, benchmarked against the Fleischner Society guidelines for CT reporting. The scans were then read independently by two consultant thoracic radiologists and two radiology specialty residents, blinded to the original reports and each other's assessments. Inter-rater variability was assessed using Light's Kappa for categorical variables and intraclass correlation coefficient (ICC) for ordinal variables.Results: Emphysema phenotype was described in 51 % of the pre-existing reports, with centrilobular emphysema being the most frequently reported subtype. Only 26 % of reports included all three key descriptors of phenotype, severity and location. Inter-rater agreement was fair for emphysema phenotype (κ = 0.371) and moderate for the grading of paraseptal emphysema (ICC = 0.733), but was more variable for associated features such as large airways disease (κ = 0.0646) and bronchiectasis (κ = 0.0996).Conclusion: This study shows variability in the quality of CT reporting for COPD in a real-world setting, with frequent omissions of key descriptors and marked inter-rater variability. These findings highlight the need for standardisation in CT reporting, particularly in the context of increasing reliance on imaging for COPD diagnosis and management.","PeriodicalId":93969,"journal":{"name":"Current problems in diagnostic radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144692813","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 secondary outcomes were to report rates of radiographic utilization and surgical intervention.Materials and methods: TriNetX was utilized to identify patients with ultimate-frisbee related injuries from 2010 to 2021 at a single institution. Injured body parts were recorded and further classified by type of injury. Imaging utilization, including plain radiograph, computed tomography (CT), and magnetic resonance imaging (MRI) were recorded. Rate of subsequent surgery was also recorded.Results: A total of 187 distinct injury encounters were identified. The most common anatomic regions injured were the knee (23.5 %), shoulder (14.8 %), and ankle (12.2 %). Among knee injuries, anterior cruciate ligament (ACL) tear was the most common type of injury (20.5 %). Sprains were the most common type of injury to the shoulder (34.5 %) and the ankle (64 %). 71.1 % of patients were imaged with radiographs, 16.6 % were imaged with MRI, and 3.7 % of patients were imaged with CT. Additionally, 14.4 % of patients required surgery due to their ultimate frisbee-related injury.Conclusion: As ultimate frisbee increases in popularity among the general population so does the incidence of ultimate-related injuries. Although these injuries have many similarities with those associated with other non-contact team sports, knowledge of the gameplay and commonly associated injury patterns is integral to initiating effective treatment and management of these injuries.","PeriodicalId":93969,"journal":{"name":"Current problems in diagnostic radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144602629","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 classical paradiscal form, where there is destruction of end plates of adjacent 2-3 vertebral bodies along with intervening disc involvement and associated paravertebral abscess is well recognized. However, due to its varied clinical and radiological presentations, it remains a diagnostic challenge often resulting in delay in diagnosis. This is especially true of countries where tuberculosis has been almost eliminated but now are witnessing increase in incidence both due to immigration and HIV infection. Overlooking tuberculosis as a differential diagnostic consideration is very likely when the radiological presentation is not classical and consequent delay in diagnosis may have devastating consequences for the patient. In this review, we aim to describe various typical and atypical imaging findings of Pott's spine with special emphasis on atypical presentations including single vertebral body involvement, isolated posterior element involvement, intraspinal epidural abscess without vertebral involvement and skip lesions along with differential diagnostic considerations like metastases, fractures and spinal infections. The major focus is on magnetic resonance imaging findings which is the imaging modality of choice in patients presenting with neurological symptoms referable to the spine. Radiographic and Computed tomography findings are also discussed in brief. We also describe treatment and post treatment imaging in brief. Radiologists need to be aware of these atypical presentations as they may be the first to raise the possibility of tuberculosis which can avoid disabling long term sequalae.","PeriodicalId":93969,"journal":{"name":"Current problems in diagnostic radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144593221","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}

Additionally, this paper examines potential prophylactic exercises and treatments for the injuries discussed.Methods: A comprehensive literature review was conducted on lower-body WMSDs among radiologists by analyzing studies related to ergonomic challenges experienced by sedentary office workers, who share similar risk factors. Topics were categorized into four groups: lower back, hips, legs, and knees. A variety of publications were also reviewed to suggest a broad range of possible interventions, including ergonomic modifications, specific exercises, and prophylactic and therapeutic regimens.Results: Lumbar spine stiffness and disk herniation were found to be the most common lower back WMSDs due to prolonged sitting. Limited passive hip extension may also contribute to the gradual development of hip osteoarthritis. Additionally, sedentary behavior has been associated with a higher prevalence of deep vein thrombosis and knee osteoarthritis. A wide range of therapeutic interventions, including effective ergonomic practices, stretching, resistance exercises, and aerobic workouts, may help prevent the development of these disorders or, at the very least, manage their symptoms.Conclusion: Diagnostic radiologists face a significant risk of lower-body ergonomic challenges due to their predominantly sedentary work habits. Addressing these issues through evidence-based interventions can enhance not only their comfort and productivity but also their long-term health.","PeriodicalId":93969,"journal":{"name":"Current problems in diagnostic radiology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144295521","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}

We evaluated whether artificial intelligence (AI) algorithms can efficiently detect radiologically significant incidental breast lesions (RSIBLs) missed by original interpreting radiologists (OIRs) on chest CT examinations.Methods: This retrospective multi-institutional study analyzed chest CT examinations performed in June 2017 by a national teleradiology practice. Visual classifier (VC) and natural language processing (NLP) algorithms flagged potential RSIBLs, which were reviewed independently by two primary readers; disagreements were adjudicated by a third reader. Sizes and margins of confirmed RSIBLs were evaluated similarly. Differences in size and margin obscuration between RSIBLs missed versus identified by OIRs were statistically assessed (alpha, 0.05). A workflow efficiency analysis was performed.Results: 3279 of 3541 examinations (92.6 %) were marked negative by both algorithms (i.e., VC-/NLP-) and not reviewed. The two primary readers assessed 262 examinations for RSIBLs, with substantial agreement (kappa, 0.77). After adjudication, 76 RSIBLs were confirmed (73 females, 3 males). Compared with the OIRs, the VC algorithm identified more RSIBLs (90.8 % [69/76] vs 39.5 % [30/76]) though with more false positives (67.9 % [178/262] vs. 3.4 % [9/262]). Among the OIRs, missed RSIBLs had smaller diameters than identified RSIBLs (1.4 cm vs. 3.0 cm; P < 0.001). Our reader workflow reduced the number of images viewed by 97.3 % relative to a hypothetical full double-read approach.Conclusion: An AI-based approach enhanced RSIBL detection rates.
