[Abstract] Objective: To investigate the diagnosis values of CT and MR imaging index for pelvic lymph node metastasis.Materials and Methods: From September 2011 to February 2015, selected 56 cervical cancer diagnosed patients in Fangxian people's hospital department of oncology, all patients were performed CT and MR imaging detection and contrast, and pathological analysis was performed.Results: In the 56 patients, clinical judgment of lymph node metastasis were 38 patients, the metastasis was 67.9%. CT analysis showed that patients with lymph node metastasis of lymph nodes as the prototype, the central necrosis, and more with the presence of extracapsular invasion, and the size of lymph nodes were significantly higher than that of patients without lymph node metastasis (P<0.05). MRI DWI images showed ADC in patients with lymph node metastasis were significantly lower than in patients without lymph node metastasis (P<0.05), but the eADC were significantly higher (P<0.05). And compared to the pathologic findings, the sensitivity of CT and MRI in the diagnosis of lymph node metastasis were 97.4% and 100.0%, specificity were all 100%, there was no statistically significant difference between the two groups (P>0.05).Conclusions: The cervical lymph node metastasis in clinical is relatively common that can lead to changes in MR imaging parameters and CT image, CT and MR imaging index for pelvic lymph node metastasis are very sensitive and specific detections that worth popularizing in clinic.
