However, the correlation between ACL injury and morphology of the proximal tibiofibular joint has not been investigated.PurposeTo compare proximal tibiofibular joint morphology in patients with injured and intact ACLs to aid in predicting and preventing ACL injuries.Material and MethodsA total of 50 patients with ACL injury and 50 individuals without structural knee damage (revealed by magnetic resonance imaging [MRI]) were included in this study. In the anteroposterior knee radiographs, the length between the proximal end of the fibular head and the medial and lateral tibia joint line were measured. In the axial knee MRI scans with the most proximal part of the fibular head, the distance calculation was performed between the most anterior point of the tibia plateau (MATP) and the most anterior point of fibular head (MAFH).ResultsThe mean length from the proximal end of the fibular head and the medial and lateral tibial joint lines was 8.7 ± 2.8 mm and 13.2 ± 2.6 mm in the ACL-injured group, and 6.5 ± 2.8 mm and 11.1 ± 2.4 mm in the control group. The length for both medial and lateral sides was significantly greater in the ACL-injured group. The length between the MATP and MAFH was significantly larger in the ACL-injured group than the control group.ConclusionA large distance between the proximal end of the fibular head and the tibial joint line and knees with posterior fibular head placement would be another anatomic risk factor of ACL injury.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"634-638"},"PeriodicalIF":1.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143522441","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 quality of DBT images may be improved by modifying technical parameters; however, the amount of raw data and postprocessing computational time is unacceptably huge. Therefore, once detected it still seems necessary to take additional spot images to characterize microcalcifications. Additional imaging increases cumulative dose. Radiation risks and protection are raising issues nowadays.PurposeTo compare image quality of magnification tomosynthesis (t-spot) and synthetic spot magnification (s-spot) to conventional spot images in characterization of microcalcifications.Material and MethodsThis prospective single institute reading study includes 45 patients with suspected microcalcifications initially found on mammography and referred to vacuum-assisted biopsy. Conventional spot and DBT were performed. Acquired DBT data were used to reconstruct t- and s-spots. All images were reviewed by four breast radiologists in two sessions. The morphology (BI-RADS) and extent of microcalcifications were recorded. Clinical performance was evaluated using area under the receiver operating characteristic curves (AUC) for BI-RADS and Bland-Altman plots for the maximum extent of microcalcifications.ResultsAll four readers preferred t-spot to s-spot. The overall AUC for t-spot was 0.67 and for spot 0.69 with a difference lower than a non-inferiority margin (delta = 0.012, 95% confidence interval [CI] = -0.067-0.09, P = 0.772). Three readers underestimate the extent of microcalcifications on t-spots for both benign and malignant cases (P < 0.05). The discordance becomes more evident with the increasing extent of the lesion.ConclusionThe performance of conventional and reconstructed spots was similar but reader-dependent and inconclusive.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"608-617"},"PeriodicalIF":1.1,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143447717","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}
