摘要
目的:分析探讨16层螺旋CT对胃癌局部侵袭范围的判断。方法:27例胃癌患者行16层螺旋CT平扫和双期增强扫描,分别利用原始横断面图像与结合后处理重建进行局部浸润范围判断,与术后病理分期进行对照。结果:横断面图像出现早期胃癌漏诊2例,局部侵袭范围判断总准确率63%;结合后处理重建后未出现漏诊,总准确率85.3%。结论:16层螺旋CT增强扫描结合重建技术可提高微小病变的检出率,对胃癌的壁内及胃周浸润判断较为可靠,能较好地进行局部浸润范围判断。
Abstract
Objective: To analyse and evaluate local invasion of gastric carcinoma by 16-slices spiral-CT. Methods: Twenty-seven patients with gastric carcinoma were scanned by 16-slices spiral-CT including plain scans and dual phase enhanced scans. Local invasion was assessed by using the transaxial scans and combining with the post-processing scans, then SCT findings were correlated with surgrical-pathologic staging. Results: Two patients with early stage of gastric carcinoma were missed on transaxial scans. The accuracy rate of judging local invasion was 63%. Combining the post-processing scans, there was no misdiagnosing case. The accuracy rate was 85.3%. Conclusion: The enhancing scan of 16-slices spiral-CT combining with reconstruction technique can improve the detection rate of small lesions, and it is reliable for judgement of invasion in stomach wall and peripheral infiltration, so that 16-slices spiral-CT can judge the local invasion of gastric carcinoma fairly well.
