This model predicts the risk of aberrant splenic artery aneurysm based on five morphological parameters derived from CTA. It provides both the probability of aneurysm occurrence and, if positive, the predicted location (proximal vs. distal SA). 本模型基于CTA成像提取的5个形态学参数，预测迷走脾动脉瘤的发生风险。模型输出发病概率，并在预测为阳性时进一步预测发病部位（近端 vs 远端脾动脉）。

CdSA CdSA (distal SA CSA) (远端脾动脉截面积)

γSA-pA γSA-pA (SA–parent artery angle) (脾动脉-主干动脉夹角)

γSMA-aA γSMA-aA (SMA–aorta angle) (肠系膜上动脉-腹主动脉夹角)
