【摘要】：目的探讨64层螺旋CT结肠成像(CTC)在结直肠癌术前定位及T分期中的应用价值。方法对59例结直肠癌患者行CTC检查,应用后处理工作站Colon软件进行图像分析,并以手术病理结果为标准,评价CTC对结直肠癌术前定位及T分期的准确率。结果 59例结直肠癌中,3例位于盲肠,9例位于升结肠,5例位于横结肠,7例位于降结肠,14例位于乙状结肠,21例位于直肠。CTC对结直肠癌术前定位及T分期诊断的准确率分别为94.9%(56/59)和88.1%(52/59)。CTC评价浆膜外侵犯的敏感度、特异度、阳性预测值、阴性预测值分别为97.7%(42/43)、81.3%(13/16)、93.3%(42/45)、92.9%(13/14)。结论 64层螺旋CTC在结直肠癌术前定位及T分期的诊断中具有重要的价值。
[Abstract]:Objective to investigate the 64 slice spiral CT colonography (CTC) in the application location and T staging of colorectal cancer. Methods 59 cases of colorectal cancer were examined with CTC, application of postprocessing workstation Colon software for image analysis, and the pathological results as the standard, the evaluation of CTC and T in colorectal cancer patients before positioning staging accuracy. Results 59 cases of colorectal carcinoma, 3 cases located in the cecum, 9 cases located in the ascending colon, 5 cases in the transverse colon, 7 cases in the descending colon, 14 cases in the sigmoid colon, the accuracy rate of 21 cases in rectal.CTC staging diagnosis of anterior positioning and T colorectal cancer were 94.9% (56/59) and 88.1% (52/59) on.CTC evaluation of subserosa sensitivity, specificity, positive predictive value, negative predictive value were 97.7% (42/43), 81.3% (13/16), 93.3% (42/45), 92.9% (13/14). Conclusion: 64 slice spiral CTC in colorectal cancer patients before positioning and T staging with Important value.
