摘要：

目的 分析比较多层螺旋CT（MSCT）影像用于诊断低度胃间质瘤和高度恶性胃间质瘤的临床效果。方法 选取2015年 1月至2017年3月我院收治的82例老年胃肠道间质瘤患者，按疾病类型分为甲组与乙组，每组41例。甲组患者为低度胃间质瘤，乙组患者为高度恶性胃间质瘤，比较两组患者应用MSCT 诊断的结果。结果 所有患者进行MSCT灌注成像扫描均未出现伪影，动态曲线较为连续，波动范围较小；两组患者的BV、MTT水平比较，差异没有统计学意义（P>0.05）；甲组患者的BF、PS 水平均明显低于乙组，差异具有统计学意义（P<0.05）。结论 MSCT 影像用于诊断老年胃肠道间质瘤可清晰判定患者疾病 的微循环情况和组织分化程度，指导后续治疗，值得临床推广。

ABSTRACT: Objective To compare the clinical effects of multi-slice spiral CT (MSCT) imaging in diagnosis of low gastric stroma and highly malignant gastric interstitial tumor. Methods From January 2015 to March 2017, a total of 82 cases of elderly patients with gastrointestinal stromal tumor in our hospital were selected and divided into group A and group B according to disease types, with 41 cases in each group. The patients in the group A suffered from low gastric stroma tumor, and the patients in the group B suffered from highly malignant gastric interstitial tumor. The results of MSCT diagnosis were compared in the two groups. Results All patients underwent MSCT perfusion imaging scans with no pseudo shadow, the dynamic curve was continuous and the fluctuation range was small. There was no significant difference in the levels of BV and MTT between the two groups (P>0.05). The levels of BF and PS in the group A were significantly lower than those in the group B, and the differences were statistically significant (P<0.05). Conclusion The multi-slice spiral CT imaging in diagnosis of elderly gastrointestinal stromal tumor can clearly estimate the patients`` microcirculation and organizational differentiation, which can guide follow-up treatment and is worthy of promotion in clinic.
KEYWORDS: multi-slice spiral CT; gastrointestinal stromal tumor; diagnosis; elderly
