摘要 AIM: To discuss the clinical value of CT three-dimensional (3-D) imaging in diagnosing gastrointestinal tract diseases.METHODS: Three-D imaging findings of 52 patients were retrospectively analyzed. Three-D imaging methods included shaded surface display (SSD), volume rendering (VR), virtual endoscopy (VE) and multiplanar reformatting (MPR). The diagnosis results of CT 3-D were evaluated by comparison with those of endoscopy and/or surgical finding.RESULTS: Fifty-two patients with gastrointestinal tract diseases were diagnosed by CT 3-D imaging, of whom 50 cases were correctly diagnosed and 2 were misdiagnosed. There were 33 cases of gastric diseases (27 with carcinoma, 5 with peptic ulcer and 1 with leiomyoma) and 19 large intestinal diseases (10 with colon carcinoma, 2 with carcinoma of the rectum, 5 with colon polypus and 2 with tuberculosis of the ileocecal junction). Twenty-two cases with prominent lesions (9 with subsequent hollow lesions), 20 with stenosis of cavity (8 with concomitant prominent lesions) and 10 with hollow lesions (5 with concomitant prominent lesions) were shown in 3-D images. The minimal lesion shown was 1.0 cm × 0.8 cm × 0.5 cm.CONCLUSION: CT 3-D imaging, a non-invasive examination without pain, can display clearly and directly the lesions of gastrointestinal tract with accurate location and high diagnosis accuracy. It is an important complementary technique to endoscopy. 瞄准:讨论 CT 的临床的价值三维(3-D ) 在诊断胃肠道疾病的成像。方法:52 个病人的 Three-D 成像调查结果回顾地被分析。Three-D 成像方法包括的遮的表面显示(SSD ) ,显示的体积(VR ) ,虚拟内视镜检查法(VE )(MPR ) 并且多平面的重新格式化。CT 3-D 的诊断结果被比较内视镜检查法或外科的发现与那些评估。结果:有胃肠道疾病的 52 个病人被 CT 3-D 成像, 50 个盒子正确地被诊断诊断, 2 被误诊。有胃的疾病的 33 个盒子(27 与癌, 5 与消化性溃疡并且 1 与平滑肌瘤) 并且 19 大肠的疾病(10 与结肠癌, 2 与直肠的癌, 5 与结肠息肉并且 2 与回盲肠连接的肺结核) 。有突出的损害的 22 个盒子(9 与随后的空损害) , 20 与洞的狭窄(8 与伴随物突出的损害) 并且 10 与空损害(5 与伴随物突出的损害) 在 3-D 图象被显示出。显示出的最小的损害是 1.0 厘米 x 0.8 厘米 x 0.5 厘米。结论:CT 3-D 成像,没有疼痛的非侵略的考试,能清楚地并且直接与精确地点和高诊断精确性显示胃肠道的损害。它是到内视镜检查法的一种重要互补技术。
