PURPOSE: To evaluate the usefulness of Gd-DTPA enhanced MR imaging in determining the metastatic lymph nodes in uterine cervical carcinoma. MATERIALS AND METHODS: Sixty nine patients with histologically proven cervical carcinoma underwent Gd-DTPA enhanced MR imaging. One hundred and thirty-eight pelvic regions(69 right,69 left) in 69 patients were analyzed for lymph node metastases. Pelvic lymph nodes were considered to be abnormal if they were greater than lcm in diameter and were enhanced on postcontrast T1 weighted images. RESULTS: Metastatic lymph nodes were found in 22 pelvic regions by surgicopathologic examinations. On MR imaging there were 14 true positives, 106 true negatives, 10 false positives and 8 false negatives. Gd-DTPA enhanced MR image had an accuracy of 86.9%, a sensitivity of 58.3%, a specificity of 91.4%, a positive predictive value of 58.3% and negative predictive value of 92.9% in evaluation of pelvic lymph node metastases. CONCLUSION: MR imaging with contrast enhancement may be useful in the evaluation of pelvic lymph node metastases in patients with uterine cervical carcinoma.
