摘　　要：目的:探讨多层螺旋CT三期增强扫描及CT后处理对胃肠间质瘤(GIST)的诊断价值。方法:回顾性分析30例经手术病理证实的GIST患者的CT增强三期扫描及应用MPR、MIP、CTA、CTV后处理图像和临床资料,采用SPSS 25.0软件进行统计分析病灶CT影像表现与病灶危险度相关性。结果:30例病理危险度分级:极低危险度8例、低危险度7例、中度危险3度、高危险度12例。GIST的不同危险度与病灶大小、形态、强化密度、供血血管异常、强化密度的差异有统计学意义(P<0.05);而在病灶部位、边缘、强化程度的差异无统计学意义(P>0.05)。结论:CT三期增强扫描及CT后处理技术有助于提高胃肠间质瘤定位、定性及危险度分级的诊断。Objective:To explore the diagnostic value of enhanced multi-slice spiral CT three-phase scanning and CT post-processing for gastrointestinal stromal tumors(GIST).Methods:A retrospective analysis of 30 patients with GIST confirmed by surgery and pathology,CT enhanced three-phase scan and application of MPR,MIP,CTA,CTV postprocessing images and clinical data,using SPSS 25.O software for statistical analysis of lesions CT imaging manifestations and lesions Risk correlation.Results:30 cases of pathological risk classification:8 cases of extremely low risk;7 cases of low risk;3 cases of moderate risk;12 cases of high risk.The differences in the different risks of GIST and the size,shape,enhancement density,blood supply abnormalities,and enhancement density of the lesion were statistically significant(P<0.05);while the differences in the location,edge,and enhancement degree of the lesion were not statistically significant(P>0.05).Conclusion:CT three-phase enhanced scanning and CT post-processing technology can help to improve the diagnosis of gastrointestinal stromal tumor location,characterization and risk classification.
