| Popis: | OBJECTIVE. The aim of this study was to compare the clinical usefulness of MRI and radioiodine (131I) whole-body scintigraphy for the detection of lymph node metastases in differentiated thyroid carcinoma (DTC).MATERIALS AND METHODS. After surgery and 131I therapy, 40 patients with DTC underwent 131I whole-body scintigraphy and MRI. Each patient was clinically suspected of having or already had evidence of nodal recurrences (confirmed by laboratory studies, cytologic analysis, or whole-body scintigraphy). Planar whole-body scintigraphy was done after administration of 111 MBq of 131I, and MRI was done using spin-echo T1- and T2-weighted imaging, T1-weighted spin-echo imaging with fat suppression, and STIR sequences.RESULTS. MRI detected nodal metastases as partly or entirely cystic and as heterogeneously enhanced on contrast-enhanced T1-weighted images. Hyperintense cystic areas appeared on T1- and T2-weighted images and STIR sequences in 57% of cases. Nodal metastases showed extracapsular spread in 24% o... |
