目的：探讨多层螺旋CT针对结肠癌术前淋巴结(LN)的转移价值判定。方法对已确诊结肠癌患者术前多层螺旋CT检查检出的LN进行分析，分别以LN长径、LN强化差值以及LN短径与长径比值等方面判定淋巴结有无转移，并与术后病理活检结果进行对照。结果多层螺旋CT对LN的转移标准：长径≥7mm、强化差值≥70Hu及短长比≥0.7等转移标准与病理结果比较一致性较好。结论多层螺旋CT做为无创、快捷的影像检查方法，依据LN的形态、强化等参数，可以在结肠癌术前对淋巴结有无转移做出较准确判断，并可以为临床对术前选择合理术式及愈后评估有重要的价值。

Objective To study the value of multi-slice spiral computed tomography (CT) in the Preoperative evaluation of lymph node metastasis.Methods Colon cancer has been diagnosed, before surgery for multislice spiral CT examination detected Lymph node metastasis analyzed. The potential lymph node metastasis was evaluated by measuring Or calculating the long diameter, extent of enhancement, and short-to-long diameter ratio of the lymph nodes. The results were compared with postoperative pathological findings. Results A long diameter ≥7mm, enhanced density ≥ 70Hu, and short-to-long diameter ratio ≥0.7 had the best consistency with postoperative Pathological findings.Conclusion As non-invasive, fast imaging method, MSCT as a non-invasive, fast imaging method, according to the LN form, strengthen and other parameters can before surgery for colon cancer lymph node metastasis to make more accurate judgments, and can be a reasonable choice for preoperative clinical surgery type and prognosis assessment has an important value.
