| 摘 要： | 目的 分析探讨64排螺旋CT结肠成像(CTC)对结直肠癌术前TN分期的价值.方法 对168例疑诊结直肠病变者进行CT扫描,其中91例有手术病理、增强CT扫描等完整资料,将影像诊断TN分期结果 与手术病理TN分期结果进行对比分析.结果 T分期总准确率为92.31%(84/91),评价肿瘤浆膜外侵犯的灵敏度、特异度分别为98.57%(69/70)和85.00%(17/20),阳性预测值和阴性预测值分别为95.83%(69/72)和94.44%(17/18).N分期总的准确率为82.42%(75/91),评价淋巴结转移的灵敏度、特异度分别为87.80%(36/41)和96.00%(48/50),阳性预测值和阴性预测值分别为94.74%(36/38)和90.57%(48/53).结论 64排螺旋CTC对结直肠癌的术前分期有重要价值.

| Abstract: | Objective To assess the value of 64-slice CT colonography (CTC) in preoperative TN staging of colorectal carcinomas. Methods One hundred and sixty-eight patients with suspected colorectal neoplasm underwent 64-slice spiral CTC after bowel cleaning and rectal air insufflating, among them 91 patients were proved with surgical pathology and enrolled into this study, and CTC images were reviewed separately by two experienced radiologists for preoperative TN staging of the tumors. Results For CTC evaluation of T staging, the sensitivity, specificity and accuracy were 98.57% (69/70), 85.00% (17/20) and 92.31% (84/91), respectively. The sensitivity, specificity and accuracy of CTC N staging were 87.80% (36/41), 96.00% (48/50) and 82.42% (75/91), respectively. Conclusion 64-slice spiral CTC plays a significant role in the preoperative TN staging of colorectal carcinoma. |
