Abstract: Objective To analyze the multi-slice computed tomography (MSCT) enhanced findings in the patients with primary small intestinal stromal tumor(SIST),and to probe the relationship between the imaging findings and the pathologic risk in order to improve the diagnostic accuracy.Methods Thirty patients with primary SIST confirmed by surgical pathology were enrolled in this study.Characterization and compassion of the clinical manifestations and MSCT enhanced findings were carried out between the pathologic low-and high-risk groups.Furthermore,the relationship was analyzed between the enhanced findings and the pathologic risk.Results Among all 30 patients with primary SIST,the lesion was located at duodenum in 5 patients (16.7%),at jejunum in 16 (53.3%),and at ileum in 9 (30%).14 patients were classified in the low risk group with the lesion with the average length of (3.8±0.9) cm,and other 16 in the high-risk group with lesion with the average length of (7.0±1.4) cm.There were no statistical differences between the low-and high-risk groups in CT value in plain and venous phase,and in added value in arterial,venous and delayed phases.However,the significantly differences were observed in CT value in arterial and delayed phases between two groups (P<0.05).Conclusion MSCT may effectively evaluate the pathologic risk of primary SIST.There are significant differences of the enhanced findings between the low-and high-risk groups,which can provide important apreoperative classification for the therapy.
