Abstract Objective: To explore the value of CT evaluation of lymph node metastasis in early-stage cervical carcinoma. Methods: Seventy-eight patients with cervical carcinoma detected by CT were enrolled in this study. The potential lymph node metastasis were evaluated by detecting factors, including the size, morphology, enhancement pattern and distribution. The results were compared with postoperative pathological finding. Results: There were 22 patients with lymph node metastasis in 78 patients. ①There were significant differences among long-to-short diameter ratio, morphology, margin, enhancement pattern(P＜0.05). There was no significant difference between extant of enhancement(P=0.715). Among the statistic results, the sensitivity and specificity of them that were using above or equal to the three CT factors was 77.27%, 82.14% respectively. ②According to the pelvic lymph nodes draining path, the lymph nodes were divided into three stages, stage two was the highest(The rate of lymph node metastasis were 11.54%, 24.36%, 7.69% respectively). Conclusion: Lymph node metastasis could be significantly diagnosed by long diameter with equal to or more than 10 mm, short-to-long ratio diameter with equal to or more than 0.7, circular or substantially circular or irregular shape, blurred edges or surrounding tissue adhesion, heterogeneous enhancement or ring enhancement. Lymph node metastasis may character as one lymph node with three features or more. Distribution of lymph nodes may partly be valuable for diagnosing lymph node metastasis.
