目的 探讨多排螺旋CT和超声 内镜对胃肠道神经内分泌肿瘤的诊断价 值。方法 回顾性分析38例经手术后病 理证实的GI-NEN的MSCT和超声内镜资 料, 并与手术病理结果相对照；分析统 计两种影像方法对GI-NEN的检出率、 T3、T4和N分期的符合率。结果 MSCT、 EUS对GI-NEN的检出率分别为81.6%、 94.7%(P=0.041)，MSCT低于EUS； MSCT 和EUS对肿瘤T3、T4和N分期的符合率 分别为T3:81.8% 、63.6%(P=0.039）, T4:77.8%、44.4%(P=0.034), N:68.8%、 43.8%,(P=0.033)，MSCT的符合率高于 EUS。结论 EUS可作为检出GI-NEN首选的 影像学检查

Objective To compare the value of multislice spiral CT (MSCT) and endoscopic ultrasonography(EUS) for diagnosis of GI-NEN. Methods The MSCT and EUS materials of 38 cases with GI-NEN confirmed by pathology were studied retrospectively and compared with pathological outcomes, the detecting rate, coincidence rate of T3,T4 and N staging by these methods were analyzed statistically. Results The detecting rate of MSCT and EUS for GI-NEN were 81.6%, 94.7%(P=0.041), respectively. The detecting rate of MSCT for GI-NEN was significantly lower than that of EUS. The coincidence rate of T3,T4 and N staging by MSCT and EUS for GI-NEN were T3:81.8% , 63.6%(P=0.039), T4:77.8%,44.4%(P=0.034),N:68.8%, 43.8%(P=0.033), respectively. The coincidence rates of MSCT was significantly higher than that of EUS. Conclusion EUS can be regarded as the preferred imaging method for detecting GINEN, MSCT can be one necessary supplementary approach for detecting GI-NEN and staging.
