In case of a single dominant feeder, antegrade embolization of this feeder might sufficiently treat the CPAF. Retrograde embolization from the pulmonary orifice is technically more challenging but leads to a complete and definite closure of the fistula in one single step.ConclusionPatient age and fistula configuration must be taken into consideration for appropriate treatment approach in CPAF.

Four indicators were measured on transverse knee MRI scans to determine the presence of patellar instability, and 450 images were labeled using Labelme software. YOLO version 8 (YOLOv8) was refined using these labeled images and validated on 100 unlabeled images.

Radiomics features were extracted from CT images, and the least absolute shrinkage and selection operator Cox regression algorithm was employed to select radiomics features. Clinical risk factors associated with DFS were selected through univariate and multivariate Cox regression analysis to build the clinical model. A predictive nomogram was developed by amalgamating pertinent clinical risk factors and radiomics features. The predictive performance of the nomogram was evaluated using the C-index, calibration curve, and decision curve. DFS probabilities were estimated using the Kaplan-Meier method.ResultsIntegrating the retained eight radiomics features and three clinical risk factors (pathological N stage, microsatellite instability, perineural invasion), a nomogram was constructed. The C-index for the nomogram were 0.819 (95% CI=0.794-0.844), 0.782 (95% CI=0.740-0.824), 0.786 (95% CI=0.753-0.819), and 0.803 (95% CI=0.765-0.841) in the training set, internal validation set, external validation set 1, and external validation set 2, respectively.

However, they have not been previously analyzed and compared directly in the same patients.PurposeTo assess and compare the potential of T1rho and UTE-T2* in the diagnosis of early IVDD in vivo.Material and MethodsThe UTE-T2* and T1rho values of 389 lumbar discs (L1/2-L5/S1) in 78 individuals were measured in three segmented disc regions. The lumbar intervertebral disc was graded using the 5-level Pfirrmann grading system and divided into three categories. Statistical analysis was performed on the regional differences of UTE-T2* and T1rho relaxometry and correlation with IVDD.ResultsBoth UTE-T2* and T1rho values were negatively correlated with Pfirrmann grade (P < 0.001). They showed strong correlations with Pfirrmann grade in NP (r = -0.725 and -0.743, respectively; P < 0.001). Diagnostic accuracy of detecting early IVDD was better with T1rho than UTE-T2* value in AAF and NP, with areas under the curve (AUCs) of 0.834-0.934 (both P < 0.05). For advanced lumbar IVDD, UTE-T2* value showed significantly higher diagnostic accuracy than T1rho in all segments with AUCs in the range of 0.743-0.893 (P < 0.05).ConclusionUTE-T2* relaxometry provided another promising magnetic resonance imaging sequence for quantitatively evaluating lumbar IVDD, especially for detection of the advanced stage of IVDD.

High-resolution 3D magnetic resonance imaging (MRI) with CT-like bone contrast (CLBC) may provide an alternative to CT in allowing complete evaluation of both bony and soft tissue structures with a single MRI examination.PurposeTo review the technical aspects of an optimized stack-of-stars 3D gradient recalled echo pulse sequence method (3D-Bone) in generating 3D MR images with CLBC, and to present a pictorial review of the utility of 3D-Bone in the clinical assessment of common musculoskeletal conditions.Material and Methods3D-Bone is a black-bone imaging technique for acquiring high-resolution 3D MR images with strong CLBC, achieved by first rendering as high a signal as possible from non-cortical bone tissues, and second by minimizing signal contrast between non-cortical bone tissues.Results3D-Bone can be used in the clinical evaluation of bony morphology in common musculoskeletal conditions. Advantages include strong bone-soft tissue contrast, resistance to motion artefacts, simple hardware and software requirements, and straightforward image processing. Disadvantages include non-specificity for cortical bone, sensitivity to susceptibility artefacts, a lack of quantitative tissue measurements, as well as overall lower image resolution and bone-soft tissue contrast compared to CT.ConclusionThe use of 3D MRI pulse sequences providing CLBC such as 3D-Bone could potentially offer complete clinical evaluation of bony morphology and soft tissues with a single MRI study for certain clinical indications, negating the need for ionizing radiation exposure from CT and reducing costs.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"228-240"},"PeriodicalIF":1.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143021735","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}
