Non-Contrast CT Radiomics Predicts Adrse Prognosis After TEVAR for Type B Aortic Dissection

Non-contrast CT-based radiomics model combining clinical factors predicted adverse prognosis after TEVAR for type B aortic dissection (AUC 0.943 training, 0.875 validation).

• Retrospective analysis of 107 TBAD patients (86 training, 21 validation) who underwent TEVAR.
• Ten radiomic features from non-contrast CT were selected and combined with clinical risk factors to build a clinical-radiomic nomogram.
• The clinical-radiomic model achieved the highest AUC (0.943/0.875) with good calibration and net clinical benefit on decision curve analysis.
