【摘要 】目的探讨模拟CT胃镜对胃部病变的诊断价值。方法选取37例已先行胃镜检查的患者(包括19例进展期胃癌，5例早期胃癌，各1例胃恶性淋巴瘤、平滑肌瘤和平滑肌肉瘤，3例胃息肉，7例胃溃疡)，行电子束CT扫描，并应用计算机软件进行图像后处理以产生模拟CT胃镜的图像，作出诊断。将模拟CT胃镜的诊断结果与胃镜和(或)手术病理结果进行对照。结果模拟CT胃镜、胃镜均全部检出了19例进展期胃癌，分别检出了3例和5例早期胃癌；模拟CT胃镜、胃镜分别检出了2例和3例胃息肉，2例和7例胃溃疡；两种方法均检出了胃平滑肌瘤、胃平滑肌肉瘤和胃恶性淋巴瘤各1例。结论模拟CT胃镜可成功地检出进展期胃癌，对早期胃癌、胃恶性淋巴瘤、胃平滑肌瘤、胃平滑肌肉瘤、胃息肉等病变的检出亦有一定的应用价值。但是，模拟CT胃镜对于Ⅱb型早期胃癌、小而表浅的胃溃疡检出有一定限制。

【 Abstract 】 Objective Evaluation of virtual computed tomography (CT) gastroscopy in diagnosing gastric disorders was executed. Methods Virtual CT gastroscopy was applied to 37 patients who had subjected to traditional gastroscopy. The diagnosis made by both scopes were verified by pathology of bioptic± resected specimens. Results The numbers of case with advanced gastric cancer (AGC, n=19) and with malignant lymphoma , leimyoma, leiomyosarcoma (n=1 each) detected by virtual CT gastroscopy were equal to that found by traditional gastroscopy. Whereas with the former scope 3 early gastric cancers (EGC), 2 gastric ulcers (GU) and 2 gastric polys were confirmed by pathology; while with the latter scope 5 EGCs, 7 GUs and 4 gastric polys proved. Conclusion Virtual CT gastroscopy is potent to diagnose various gastric diseases but is of limitation to detect EGC of IIb and small superficial GU.
