【摘要】 目的：探讨动态增强CT扫描对子宫肌瘤的诊断价值。材料与方法：对32例39个子宫肌瘤进行平扫、动态增强扫描及延迟扫描，观察子宫肌瘤在三种扫描方式的CT表现及比较其检出敏感性，同时与对照组采用常现增强扫描的24例27个子宫肌瘤进行检出敏感性、内部结构及边缘显示率的比较。结果：子宫肌瘤在平扫、动态增强扫描、延迟扫描的检出敏感性分别为17．9％、92．3％、35．9％。动态增强扫描的检出敏感性、内部结构及边缘显示率均高于常规增强扫描。结论：动态增强扫描可明显提高子宫肌瘤的检出率，可清楚显示肿瘤的血供、内部结构及边缘特征，对子宫肌瘤有很大的诊断价值，优于常规增强扫描。更多还原

【Abstract】 Objective:To evaluate the diagnostic value of dynamic enhanced CT scan to uterine leiomyomas. Materials and methods: 39lesions of uterine leiomyomas in 32 patients underwent plain scan, dynamic enhanced scan and delay scan, to study the CT appearances of uterine leiomyomas under three different scan modes and commpare their sensitivity. Twenty seven lesions of 24 patients in control group withroutine enhanced scan were compared with dynamic enhanced scan in the sensitivity, inside structure and marginal display rate. Results: Thestudy showed that the sensitivity in detecting lesions in plain scan, dynamic enhanced scan and delay scan were respectively 17. 9%, 92. 3%and 35. 9% .The significant differences of the sensitivity, inside structure and marginal dispay rate were also found between dynamic androutine enhanced scan. Conclusion: Dynamic enhanced CT scan can considerably immprove detecting rate of uterine leiomyomas, show clearlyblood supply, inside structure and marginal feature of tumors. It is of great diagnostic value to uterine leiomyomas and much superior to routine enhanced scan.更多还原
