摘　　要：目的：评价薄层动态增强CT扫描三维重建技术对胃癌的诊断价值。方法：对62例胃癌病例行气体对比薄层动态增强CT扫描三维重建技术,层厚1～2 mm,在此基础上进行CT仿真胃镜和VRT技术,对获取的图像进行分析。全部病例均经手术和病理证实。结果：检出病变位于胃窦部31例（50%）,胃底贲门部10例（16%）,体部9例（15.7%）,弥漫型12例（19.3%）,病变检出率为100%。多薄层动态增强CT扫描三维重建技术表现为局限性胃壁增厚50例,广泛性胃壁增厚12例;其中早期胃癌10例,进展期胃癌52例;局部和远处淋巴结转移24例;远处转移17例;本组CT定性诊断准确率为96%。结论：薄层动态增强CT扫描三维重建技术能清晰显示胃壁及腔内、外病变,并直观反映胃癌大体形态及肿瘤的范围,在胃癌的定位、定性和定量诊断中发挥其独特的优势,是一种最具潜力的检查方法。Objective：To evaluate value of the thin slice dynamic enhanced CT three dimensional reconstruction technique （3D） in diagnosis of gastric carcinomas. Methods：A total of 62 patients with gastric carcinomas underwent he thin slice dynamic enhanced CT three dimensional reconstruction techniques with a slice thickness of 1 - 2 mm . VRT and virtual endoscope were used for these gastric carcinomas. Which were analyzed？ Before CT scanning, two packs （6g） of gas contrast medium were given orally to each patient. The CTVG and volume rendering （VR） were used for these patients . All cases were confirmed either by surgiopathology or by endoscopic biopsy. Results： In these 62 cases, there were 31 examples（50% ） locating the gastric antra, stomach bottom cardia 10 cases （ 16% ）, gastric body 9 cases （ 15.7% ）, widespread type 12 examples （ 19.3% ）, MSCT accuracy of discovering the gastric lesions reached to 100%. CT manifestation ： gastric wall confining thickened in 50 cases and extensive thickened in 12 cases, of which 28 and 34 cases with gastric carcinoma were early and advanced. The part transfer with lymphoid node in distant place 24 cases, the distant place transfer 17 cases, MSCT accuracy of determining the nature of the lesion reached to 96%. Conclusions ： Thin slice dynamic en- hanced CT three dimensional reconstruction technique can display lesion in the gastric wall, inside and outside cavity clearly , it also can reflect shape and extension of the tumor directly and play to its unique advantage in the locating, qualitative and quantifying of gastric carcinomas, so it is a kind of most potential inspection method.
