Searches were performed in MEDLINE, Cochrane Library, PubMed, ScienceDirect, and Google Scholar on December 1, 2024. Eligible studies included those with clinically diagnosed PMD and MRI findings. Data on patient characteristics, MRI sequences, thrombus stage, and study quality were extracted and assessed using the Joanna Briggs Institute checklist for case reports.Results: From 710 records, four studies were included, encompassing four patients with PMD. The median age of the four patients is 35.5 years old (25-53), and two are from Turkey. MRI findings highlighted variable thrombus stages (one acute, two subacute, and one chronic) and heterogeneous imaging protocols. Only one study explicitly mentioned MRI indications. MRI provided detailed assessments of penile anatomy and thrombus characteristics but lacked consistency in usage, timing, and sequence protocols. No studies received a good quality rating; two were rated poor, and one was fair.Conclusion: MRI's role in PMD diagnosis is limited, with its utility primarily in complex or atypical cases. Standardized MRI indications and sequence protocols are warranted to optimize its clinical application. More extensive studies are needed to validate its diagnostic and therapeutic impact.Advances in knowledge: MRI is primarily utilized for complex cases of PMD; however, more systematic documentation of its indications could guide clinicians in determining when MRI is appropriate for PMD patients.

The first endpoint was the invasive coronary angiography (ICA) efficiency, defined as the ICA with non-obstructive disease (stenosis <50%) and the ratio of revascularization to ICA (REV-to-ICA ratio) within 90 days. The second endpoint was the incidence of major adverse cardiac events (MACE) at 2 years.Results: A total of 461 patients (267 [57.9%] men; median age, 64 [55-69]) were included. At 90 days, the rate of ICA with non-obstructive disease in CT-FFR+CCTA group was lower than the CCTA group (14.7 vs. 34.0%, P = 0.047). The REV-to-ICA ratio in the CT-FFR+CCTA group was significantly higher than the CCTA group (73.5% vs. 50.9%, P = 0.036). No significant difference in ICA efficiency was found in intermediate stenosis (25-69%) between the two groups (all P > 0.05). After a median follow-up of 23 (22, 24) months, MACE were observed in 11 patients in the CT-FFR+CCTA group and 24 in the CCTA group (5.9% vs. 10.0%, P = 0.095).Conclusion: The on-site deep learning-based CT-FFR improved the efficiency of ICA utilization with the similarly low rate of MACE compared with CCTA alone.Advances in knowledge: The on-site deep learning-based CT-FFR was superior to CCTA for therapeutic management.","PeriodicalId":9306,"journal":{"name":"British Journal of Radiology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143662273","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this multi-centre study is two-fold: (1) to evaluate the repeatability of manual ROI-based analysis of srT1, (2) to validate a semi-automated measurement method with an automatic quality control (QC) module to identify likely discrepancies between automated and manual measurements.Methods: Pancreatic MRI scans from a scan-rescan cohort (46 subjects) were used to evaluate the repeatability of manual analysis. 708 scans from a longitudinal multi-centre study of 466 subjects were divided into training, internal validation (IV), and external validation (EV) cohorts. A semi-automated method for measuring srT1 using machine learning is proposed and compared against manual analysis on the validation cohorts with and without automated QC.Results: Inter-operator agreement between manual ROI-based method and semi-automated method had low bias (3.8 ms or 0.5%) and limits of agreement [-36.6, 44.1] ms. There was good agreement between the two methods without automated QC (IV: 3.2 [-47.1, 53.5] ms, EV: -0.5 [-35.2, 34.2] ms). After QC, agreement on the IV set improved, was unchanged in the EV set, and the agreement in both was within inter-operator bounds (IV: -0.04 [-33.4, 33.3] ms, EV: -1.9 [-37.6, 33.7] ms).

Despite a wealth of exploratory analysis performed on scans acquired from patients with lung cancer and existing guidelines describing some of the key steps, no radiomic-based biomarker has been widely accepted. This is primarily due to limitations with methodology, data analysis and interpretation of the available studies. There is currently a lack of guidance relating to the entire radiomic workflow from study design to critical appraisal. This guide, written with early career lung cancer researchers, describes a more complete radiomic workflow. Lung cancer image analysis is the focus due to some of the unique challenges encountered such as patient movement from breathing. The guide will focus on CT imaging as these are the most common scans performed on patients with lung cancer.

We investigated its reliability and classification performance on more commonly acquired T1 MPRAGE and FLAIR images.Methods: SA was measured on axial MPRAGE and FLAIR images in 57 subjects (19 NPH, PD and HC each) by two raters, and compared across groups. Receiver operating characteristics (ROC) analysis was used to assess its classification performance differentiating NPH from non-NPH groups, in comparison to the CA.Results: Inter-rater reliability for SA were excellent (intraclass correlation coefficients ≥0.91). SA was effective in differentiating NPH from non-NPH patients on MPRAGE and FLAIR images (p < 0.001). Its ROC curves showed excellent performance classifying NPH from HC (AUC 1) and PD (AUC >0.93) groups, and were highly comparable to those for CA (1; 0.947). Angles wider than 60° and narrower than 45° robustly (100%) excluded and predicted NPH from HC, respectively. The narrower 45° cutoff yielded better sensitivity (84.2-89.5%) in differentiating NPH from PD patients.Conclusions: The SA on MPRAGE/FLAIR images showed excellent inter-rater reliability and classification performance predicting NPH from non-NPH groups, rivalling those of the CA.Advances in knowledge: The SA on MPRAGE and FLAIR images is reproducible and shows excellent diagnostic performance differentiating NPH from non-NPH groups, with potential to replace the CA in NPH screening given its accessibility on routine axial neuroimaging.","PeriodicalId":9306,"journal":{"name":"British Journal of Radiology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143633739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their rarity and complexity makes diagnosis challenging. These syndromes can present in a number of different ways clinically and radiologically. A systematic method of image interpretation often reveals a pattern, allowing the diagnosis to be narrowed or further testing to be directed. Although the CNS vascular appearance itself is rarely specific, additional information gleaned from imaging other systems aids in pattern recognition. We retrospectively reviewed pediatric cases of CNS vasculopathy with a confirmed diagnosis of a syndromic disorder. We recorded the predominant CNS vascular appearance in each case, and assessed imaging clues from multiple systems, including brain, orbits, skull, spine, long bones, viscera and skin. Several of these syndromes also had systemic vascular involvement, which allowed further categorization. Some imaging patterns allowed a specific diagnosis to be made. In other cases, the constellations of imaging appearances helped distinguish between clinically similar phenotypes. The imaging pattern within each pediatric CNS vascular syndrome is fairly consistent, and awareness of these syndromes and expected imaging patterns allow the radiologist to suggest further imaging or targeted genetic testing.","PeriodicalId":9306,"journal":{"name":"British Journal of Radiology","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143623556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
