多层螺旋CT动态增强扫描在结肠淋巴瘤诊断中的应用

目的探讨多层螺旋CT（MSCT）动态增强扫描诊断结肠淋巴瘤的价值。方法对16例结肠淋巴瘤患者进行MSCT动态增强扫描,并观察分析MSCT轴位图像和多平面重组（MPR）、容积重建（VR）及CT仿真内窥镜（CTVE）等重建图像,进行诊断。同时行双对比钡灌肠检查和纤维结肠镜检查。结果16例结肠淋巴瘤患者中B细胞型淋巴瘤14例,MSCT动脉期增强扫描见病灶呈轻、中度均质强化,诊断为结肠淋巴瘤;T细胞型淋巴瘤2例,MSCT动脉期增强扫描呈中度不均质强化,诊断为结肠癌。MSCT动态增强扫描与病理诊断的符合率为87．5％,高于双对比钡灌肠检查和纤维结肠镜检查。结论MSCT动态增强扫描结合后处理图像在结肠淋巴瘤的诊断中具有独特的优越性,其诊断符合率高于双对比钡灌肠检查和纤维结肠镜检查。

The application of multi-slice CT dynamic enhancement scan in the diagnosis and treatment of colonic lymphomas

Objective To discuss the value of multi-slice CT dynamic enhancement scan in the diagnosis and treatment of colonic lymphomas. Methods 16 patients with colonic lymphomas underwent multi-slice CT dynamic enhancement scans, images of axial and reconstructive images of VR, MPR and CTVE were analyzed, patients were respectively diagnosed. Results Appearances of primary colorectal lymphomas were categorized into focal and diffuse lesions. Focal and diffuse lesions were 6 and 10 patients, respectively. The accuracy rate of diagnosis was 87.5%. Conclusion MSCT dynamic scan has distinctive superiority in diagnosis and treatment of colonic lymphomas.
