PURPOSE: The purpose of this study was to ascertain the usefulness of MR imaging in the diagnosis of nodal metastasis of papillary thyroid carcinoma and to establish the most indicative MR criteria of metastasis. METHODS: Pathologic records and MR images in 50 patients with papillary thyroid carcinoma were reviewed. Each neck was divided into four nodal levels, so that 200 nodal levels were assessed in all. The maximum of the minimum transverse diameters of the lymph nodes on each nodal level measured on MR images and the certainty of metastasis as determined by a head and neck radiologist on the basis of morphologic aspects were compared with the pathologic findings by using receiver operating characteristic curves. The presence or absence of cystic nodes on each nodal level was also evaluated. RESULTS: Metastasis was found on 87 (44%) of the nodal levels in 34 (68%) of the patients. A cystic node was identified on 33 (17%) of the nodal levels in 13 (26%) of the patients and was seen only on positive nodal levels. Morphologic diagnosis by the radiologist was better than that obtained by measurement. With the combined criteria of a cystic node or a node of 13 mm or more for the maximum of the minimum transverse diameters, specificity was 100% with an 82% accuracy and always indicated metastasis (100% positive predictive value). However, 41% of the metastatic nodes were missed with this criterion (59% sensitivity). CONCLUSION: MR imaging was useful for diagnosing metastatic nodes; a nodal diameter threshold of 13 mm or the presence of a cystic node strongly indicated metastasis from papillary thyroid carcinoma.
