CT增强结合血管成像对大肠癌患者诊断价值的分析

目的分析多层螺旋CT增强扫描结合血管成像对大肠癌患者术前诊断价值的探讨。方法收集就诊于我院普外科的大肠癌患者50例，术后经过病理证实，且术前已完善多层螺旋CT增强扫描及结合血管成像检查，对术后病理证实的结果与CT检查提示的征象进行比较。结果所有大肠癌患者术后的病理结果与患者术前多层螺旋CT增强扫描及结合血管成像相比无明显异常，无统计学意义（P〉0．05）。同时在对大肠癌进行术前分期的评估中，多层螺旋CT增强扫描结合血管成像对其正确的诊断率为86．0％。结论对大肠癌患者术前完善多层螺旋CT增强扫描结合血管成像很有必要，其可为临床医生的手术方法及术后治疗提供一定的帮助，具有良好的术前诊断价值，值得在临床上推广。

Analysis of the diagnostic value of contrast-enhanced CT scans combined with preoperative angiography in patients with colorectal cancer

Objective To analyze the value of multi-slice spiral CT scan combined with angiography in the preoperative diagnosis of colorectal cancer. Methods Fifty patients with colorectal cancer treated in the department of general surgery of our hospital scanning combined with angiography, and were , who underwent preoperative multislice CT enhancement postoperatively confirmed by pathology, were included in this study. The results of postoperative pathology were compared with the CT-revealed signs. Results The comparison of postoperative pathological results of all patients with the preoperative multi-slice spiral CT enhanced scan and angiography showed no obvious abnormality and no statistically significant difference （P 〉 0.05）. In the colorectal cancer staging and assessment, the preoperative diagnosis rate of multi-slice spiral CT enhanced scan and angiography was 86.0%. Conclusions It is necessary for the patients with colorectal carcinoma to do enhanced spiral CT scanning combined with angiography. It can provide some helpful information for clinicians in operation method decision and postoperative treatment. It has also good value in preoperative diagnosis. So it is worth promoting in clinical practice
