摘要
目的探讨多层螺旋CT(MSCT)仿真内镜技术(CTVE)在胃间质瘤与胃癌鉴别诊断中的临床应用价值。资料和方法临床疑似胃占位性病变71例,行MSCT扫描并进行CTVE重建。CTVE诊断结果与胃镜或手术后病理结果进行对照。结果经病理证实胃间质瘤18例,胃癌26例,CTVE敏感度为93.2%,特异度为96.3%。CTVE显示腔内型间质瘤呈类球形腔内肿块伴顶端溃疡形成;腔外型间质瘤表现为丘状隆起、桥形皱襞;BorrmannⅠ、Ⅱ型胃癌呈息肉样向胃腔内突出,或伴不规则溃疡;BorrmannⅢ、Ⅳ型胃腔不同程度变窄,伴不规则溃疡形成、胃壁皱襞消失。结论 CTVE在胃间质瘤与胃癌鉴别诊断方面有一定的临床应用价值,但需要注意结合轴位图像及临床资料做出诊断。
Purpose To explore the clinical application value of the multi-slice spiral CT （MSCT） virtual endoscopy （CTVE） in the differential diagnosis of gastric stromal tumor and gastric cancer. Materials and Methods A total of 71 cases of suspected gastric lesions were performed MSCT scan and CTVE reconstruction. Image diagnosis was compared with endoscopy or surgical pathology results. Results Pathologically confirmed 18 cases of gastric stromal tumors and 26 cases of gastric cancer. The sensitivity of CTVE was 93.2%, the specificity was 96.3%. CTVE showed the intraluminal type gastric stromal tumor was a spherical intraluminal mass with a the ulcer at the top. The extraluminal gastrointestinal stromal tumor was mound-shaped uplift or bridge-shaped folds. Borrmann Ⅰ, Ⅱ type gastric cancer showed a polypoid prominent to the gastric lumen, or with irregular ulcers. Borrmann Ⅲ, Ⅳ gastric cancer showed stomach cavity narrowing to varying degrees, with irregular ulceration, and gastric folds disappearance. Conclusion CTVE has a certain clinical application value in the differential diagnosis of gastric stromal tumor and gastric cancer, but the axial images and clinical information should also be considered.
