Currently, biliary complications are among the main factors affecting the survival rate and quality of life of liver transplant recipients. Nevertheless, the clinical manifestations of biliary complications following liver transplantation are often non-specific, making early diagnosis and timely treatment crucial for improving patient outcomes. Ultrasound is the preferred imaging method following liver transplantation. Importantly, contrast-enhanced ultrasound, with the administration of contrast agents, can improve the resolution of biliary images and enable real-time, dynamic visualization of microcirculation perfusion in the biliary system and surrounding tissues. The present article describes the normal ultrasonic features of the biliary system following liver transplantation and briefly reviews the progress in the ultrasonic diagnosis of common biliary complications, including anastomotic biliary strictures, non-anastomotic biliary strictures, biliary leakage, biloma, and bile sludge/bile stone.","PeriodicalId":23819,"journal":{"name":"World journal of radiology","volume":"17 7","pages":"106556"},"PeriodicalIF":1.5,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12308602/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144761544","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, determining the computed tomography (CT) scanning range has relied on manual methods due to limited automation in this area.Aim: To develop and evaluate a novel deep learning approach to automate the determination of CCTA scan ranges using anteroposterior scout images.Methods: A retrospective analysis was conducted on chest CT data from 1388 patients at the Radiology Department of the First Affiliated Hospital of a university-affiliated hospital, collected between February 27 and March 27, 2024. A deep learning model was trained on anteroposterior scout images with annotations based on CCTA standards. The dataset was split into training (672 cases), validation (167 cases), and test (167 cases) sets to ensure robust model evaluation.Results: The study demonstrated exceptional performance on the test set, achieving a mean average precision (mAP50) of 0.995 and mAP50-95 of 0.994 for determining CCTA scan ranges.Conclusion: This study demonstrates that: (1) Anteroposterior scout images can effectively estimate CCTA scan ranges; and (2) Estimates can be dynamically adjusted to meet the needs of various medical institutions.","PeriodicalId":23819,"journal":{"name":"World journal of radiology","volume":"17 7","pages":"110394"},"PeriodicalIF":1.5,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12308584/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144761545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It affects approximately 50% of women over the age of 50 and significantly impacts their quality of life. The causes of ODS include structural abnormalities such as rectocele, enterocele, intussusception, and pelvic floor descent, as well as functional disorders like anismus. Accurate diagnosis is crucial for effective management due to the high risk of treatment failure associated with inaccurate findings. Various imaging modalities are used to assess pelvic floor disorders, including fluoroscopic defecography (FD), magnetic resonance defecography (MRD), pelvic floor ultrasound (PFUS), and echodefecography (EDF). FD is the most commonly performed test worldwide, offering high accuracy in diagnosing pelvic floor disorders. It provides dynamic visualization of defecation mechanics but involves radiation exposure. MRD offers excellent soft tissue detail and multiplanar imaging without radiation, making it particularly useful for multicompartment disorders; however, it is associated with high procedural costs and limited availability. Both PFUS and EDF are minimally invasive and avoid radiation exposure. PFUS shows promise as a valuable screening tool that could help minimize the need for advanced imaging if findings are normal. EDF is also promising but requires specialized training and remains less widely available. This review evaluates the accuracy, advantages, and limitations of various diagnostic modalities for pelvic floor disorders, aiming to guide optimal clinical decision-making.","PeriodicalId":23819,"journal":{"name":"World journal of radiology","volume":"17 7","pages":"107459"},"PeriodicalIF":1.5,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12308581/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144761546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scoring system incorporated five parameters: (1) Tumor size; (2) Portal venous phase density; (3) Necrosis; (4) Peripancreatic infiltration; and (5) Suspected metastatic lymph nodes. While demonstrating satisfactory recurrence prediction capability without requiring complex technologies, thereby supporting clinical utility in Chinese populations, the study exhibited notable limitations. Most analyzed patients lacked neoadjuvant chemotherapy exposure, resulting in underrepresentation of low-risk subgroups. Additionally, the short follow-up duration potentially compromised long-term prognostic assessment. Contemporary advances in radiomics coupled with machine learning have enhanced multimodal data integration for PDAC management. However, clinical implementation continues to confront challenges including variability in imaging parameters, incomplete understanding of molecular underpinnings, and confounding treatment effects. Future investigations should prioritize developing multidimensional predictive frameworks that synergize radiographic, molecular, and clinical data.

Conventional imaging modalities, such as computed tomography (CT) and magnetic resonance imaging (MRI), primarily provide anatomical information, whereas 18F-fluorodeoxyglucose positron emission tomography/CT (18F-FDG PET/CT) integrates functional metabolic and anatomical imaging, serving as a critical complementary tool in the diagnosis and management of STS. This article reviews recent advances in the application of 18F-FDG PET/CT for STS. The advantages of 18F-FDG PET/CT in STS include: (1) Early detection of metabolic activity changes in tumors, particularly when morphological alterations are insignificant; (2) Effective differentiation between benign and malignant soft tissue tumors, as well as aiding in distinguishing high-grade from low-grade sarcomas; (3) Identification of occult metastatic lesions, improving staging accuracy, and facilitating restaging in cases of recurrence or metastasis; (4) Utilization of parameters such as maximum standardized uptake value and metabolic tumor volume to assist in tumor grading and prognostic evaluation; and (5) Monitoring treatment response to guide adjustments in personalized therapeutic strategies. However, 18F-FDG PET/CT has limitations in diagnosis of certain STS subtypes (e.g., myxoid liposarcoma), detection and biopsy of metastatic lymph nodes, necessitating integration with clinical evaluation and other imaging techniques. 18F-FDG PET/CT is poised to play an increasingly vital role in the precision diagnosis and treatment of STS.","PeriodicalId":23819,"journal":{"name":"World journal of radiology","volume":"17 7","pages":"106427"},"PeriodicalIF":1.5,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12308547/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144761541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An implantable cardioverter defibrillator (ICD) prevents SCD and dramatically reduces the arrhythmic events in these patients; hence, the risk stratification for the SCD is important. In survivors of out-of-hospital cardiac arrest, identification of its etiologies is required to select the appropriate treatments following ICD installation. Cardiac magnetic resonance imaging (MRI) is useful for evaluating the morphology and function of the heart and for tissue characterization, MRI can therefore be used to stratify the risk of SCD associated with various myocardial diseases and leads to primary prevention using ICD. MRI can predict arrhythmic events, which suggest the progression of myocardial damage, following secondary prevention. In this review, we provide a clinical and MRI focused update and MRI protocol for the primary and secondary prevention of SCD.
