All patients underwent laboratory assessments and 4D flow MRI using a 3-T scanner to analyze hemodynamic parameters within the main portal vein (PV), splenic vein, and superior mesenteric vein. Comparative analysis of 4D flow parameters among the groups was performed using the Mann-Whitney U-test, and diagnostic accuracy was assessed through the area under the receiver operator characteristic curve (AUC).ResultsIn the main PV, all 4D flow parameters were significantly lower in patients with a positive RC sign compared to those with a negative RC sign (P < 0.05). Patients with EVB had lower parameters than those without EVB (P < 0.05). The AUC values predicting actual variceal bleeding was 0.762 for endoscopy alone and 0.770-0.787 for 4D flow MRI.

Patients' age and sex, tumor location (mediastinum or thoracic wall), tumor size, MR characteristics including necrosis or hemorrhage, and ADC values were assessed.ResultsMalignant masses were found in older patients (mean age = 18.0 ± 8.1 vs. 10.6, ± 9.1 years; P = 0.008), had lower mean ADC values (0.765 ± 0.298 vs. 2.051 ± 0.855 × 10-3 mm2/s; P < 0.001), and showed more internal hemorrhage (6/12 vs. 17/86; P = 0.031) compared to benign masses. Univariate and multivariate regression analyses also showed significant differences in age, tumor size, and ADC values. In the diagnostic performance analysis, age (area under the receiver operating characteristic curve [AUC] = 0.723, 95% confidence interval [CI] = 0.624-0.809; P = 0.004) and ADC mean value (AUC = 0.941, 95% CI = 0.874-0.978, P < 0.001) were significant. The optimal cutoff values were 13 years for age (sensitivity = 83.3%, specificity = 61.6%) and an ADC mean of 1.196 × 10-3 mm²/s (sensitivity = 100%, specificity = 86.1%) for discriminating malignant from benign thoracic masses.ConclusionWhen evaluating thoracic masses in children and young adults, older age and lower ADC values help identify malignancy.","PeriodicalId":7143,"journal":{"name":"Acta radiologica","volume":" ","pages":"393-400"},"PeriodicalIF":1.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143027734","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}
