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.
