| 摘 要： | 目的：探讨螺旋CT（SCT）及MRI对进展期胃癌T分期的价值。方法：通过采用水充盈技术，应用螺旋CT和高场强MR对30例经手术证实的进展期胃癌患者在术前行SCT、MRI平扫及动态增强扫描，并与手术病理结果进行对照。结果：SCT及MRI判断T分期的准确率分别为83．3％（25／30），90．0％（27／30）。SCT及MRI判断Tz期的准确率分别为77．8％（7／9），88．9％（8／9）；T。分期的准确率分别为84．6％（11／13），92．3％（12／13）；T4分期的准确率分别为87．5％（7／8），87．5％（7／8）。结论：MRI对胃癌T分期的判断准确性略高于螺旋CT，MRI以其多平面及多参数成像的特点与螺旋CT在评价胃癌T分期方面进行互补。

| Abstract: | Objective: To evaluate the diagnostic accuracy of spiral CT and magnetic resonance imaging for T-staging of advanced gastric carcinomas.Methods:With water filling,spiral CT and MRI examination was performed in 30 cases of advanced gastric carcinomas diagnosed by the operation,spiral CT and MRI dynamic enhanced scanning were also applied.Spiral CT and MRI findings were compared with postoperative pathology.Results:The accuracy of T-staging with SCT and MRI were 83.3%(25/30)and 90.0%(27/30)respectively,and th... |
