Pelvic bone marrow DWI signals (b = 800 s/mm2) were classified as high and iso-low signal groups. Factors influencing the DWI signal were analyzed individually in a multifactorial analysis. Subsequently, a comparison was made of the intravoxel incoherent motion (IVIM) parameters between the high and iso-low signal groups.ResultsThe study involved 73 patients, with 32 in the high-signal and 41 in the iso-low-signal groups. The multifactorial analysis showed that anemia (odds ratio [OR] = 5.264; P = 0.025) and proton density fat fraction (PDFF) (OR = 0.872; P <0.001) were independent factors influencing the DWI signal. In addition, the high-signal group demonstrated significantly lower values of the standard apparent diffusion coefficient (ADC) (median = 0.466 ×10-3 mm²/s, interquartile range = 0.413-0.550 vs. 0.534 ×10-3 mm²/s, interquartile range = 0.495-0.594; P <0.01) and the mean diffusion coefficient (D) (0.423 ± 0.065 vs. 0.482 ± 0.090, × 10-3 mm²/s; P <0.01).ConclusionThe evaluation of pelvic bone marrow function through DWI signals is feasible in middle-aged and elderly patients with rectal cancer. A high DWI signal in the pelvic bone marrow correlates with post-anemic cellular proliferation, indicating active hematopoiesis.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"2841851251360344"},"PeriodicalIF":1.1,"publicationDate":"2025-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145074088","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}

Patients were assigned to either the HAIC + TKI group (n = 40) or the TACE + TKI group (n = 46) based on multidisciplinary team recommendations, considering tumor burden, vascular invasion, and patient preference. Overall survival (OS) was evaluated using Kaplan-Meier analysis, and treatment-related adverse events (AEs) were recorded.ResultsThe median OS was 13.7 months in the HAIC group and 8.3 months in the TACE group (hazard ratio = 0.5489, 95% confidence interval = 0.3557-0.8472; P = 0.00661).

To avoid the administration of contrast medium, the non-contrast MRI scoring (NCMS) system was proposed.PurposeTo evaluate the contribution of detecting intra-tumoral hemorrhage in the solid tissue of adnexal masses to improve tumor characterization and enhance the risk stratification of adnexal lesions using the NCMS system.Material and MethodsMRI findings including susceptibility-weighted sequences (T2*-weighted MR angiography [SWAN]) were retrospectively analyzed in 126 surgically confirmed adnexal tumors with solid tissue components (20 benign, 106 malignant). Solid tissue was classified as malignant based on the NCMS criteria, defined by intermediate intensity on T2-weighted (T2W) imaging, and corresponding diffusion restriction. Hemorrhage was assessed based on high intensity on T1-weighted (T1W) imaging and susceptibility-related signal voids on SWAN.ResultsThe NCMS solid tissue criteria identified malignancy with a sensitivity of 94.3%, specificity of 60%, and accuracy of 88.9%. High intensity on T1W imaging and signal voids on SWAN were observed in 23.6% and 72.6% of malignant lesions, compared to 0% and 5% in benign lesions, respectively. Hemorrhage was frequently observed in high-grade malignant tumors, or hemorrhagic subtypes. The combination of NCMS criteria and/or presence of intra-tumoral hemorrhage was associated with malignancy, yielding a sensitivity of 98.1%, specificity of 60%, and accuracy of 92.1%.ConclusionThe inclusion of intra-tumoral hemorrhage enhances the diagnostic accuracy of the NCMS for characterizing adnexal lesions. SWAN may also aid in estimating tumor grade and identifying hemorrhagic subtypes.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"935-946"},"PeriodicalIF":1.1,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143958035","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}
