【摘要】 目的:评价螺旋CT多期增强扫描诊断肾癌的价值。材料与方法:对29例CT平扫疑为肾癌的患者(最终病理证实)全部行螺旋CT多期增强扫描及模拟同层动态增强扫描与B超检查,对结果进行对照分析。结果:肾癌螺旋CT多期增强扫描表现:1肾癌呈实质强化19例,星点状强化10例;2肾癌强化特点为一过性快进快出;3呈实质性强化肾癌,螺旋CT多期增强扫描诊断率(19/29)与同层动态增强扫描(19/29)及B超(17/29)无显著差别;在少血流星点状强化肾癌,螺旋CT多期增强扫描诊断率(10/29)与同层动态增强扫描(4/29)及B超(5/29)有显著差别(P<O.05)。结论:螺旋CT多期增强扫描诊断肾癌准确性高。更多还原

【Abstract】 Purpose:To evaluate multi-time spiral CT contrast scanning in the diagnosis of renal carcinoma.Materials and Meth- ods:Multi time CT contrast scanning was performed in 29 patients with suspected renal carcinoma(final confirmed by pathology).The results were compared with DCT and US.Results:CT feature of renal carcinoma by using multi-time contrast of spiral CT:1 Enhancement of tumor masses are in 19 patient;Astro-style enhancement of tumor are 10 patient.2 The contrast characteristic of renal carcinoma show once at early period.3 For enhancemnt of tumor masses,The diagnostic rate between multi-time CT contrast(19/29)and DCT(19/29)and US(17/29) had no difference.For hypo-perfused and astro-style enhancement of tumor,The diagnostic rate between multi-time CT contrast(10/29)and DCT(4/29)and US(6/29)had difference(P<0.05).Conclusion:The multi-time contrast by spiral CT played an important role in preoper- ative evaluation of renal carcinoma.更多还原
