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
Objective To investigate the diagnostic value of simulated CT endoscopy in gastric lesions. Methods Thirty-seven patients (including 19 advanced gastric cancer, 5 early gastric cancer, 1 gastric malignant lymphoma, leiomyoma and leiomyosarcoma, 3 gastric polyps and 7 gastric ulcer) were enrolled in this study. Electron beam CT scan, and the application of computer software for image post-processing to produce images of simulated CT gastroscopy to make a diagnosis. The diagnosis of CT endoscopy diagnosis and endoscopy and / or surgical pathology results were compared. Results Nineteen cases of advanced gastric cancer were detected by CT endoscopy and endoscopy respectively. Three cases and five cases of early gastric cancer were detected respectively. Two cases and three cases of gastric polyp were detected by gastroscopy, Cases of gastric ulcer; two methods were detected in gastric leiomyoma, gastric leiomyosarcoma and gastric malignant lymphoma in 1 case. Conclusion Simulated CT gastroscopy can successfully detect advanced gastric cancer, and has certain value in the detection of early gastric cancer, gastric malignant lymphoma, gastric leiomyoma, gastric leiomyosarcoma, gastric polyps and other lesions. However, simulated CT gastroscopy for type IIb early gastric cancer, small and superficial gastric ulcer detection has a certain limit
