Lee DH, et al. - Researchers retrospectively analyzed 76 cytopathologically confirmed focal thyroid lesions to ascertain the utility of dual-energy CT (DECT) iodine quantification to classify the focal thyroid lesions. They obtained iodine concentration values of thyroid nodules (IC_N) highest in the benign nodule, lower in the papillary thyroid carcinoma (PTC), and the lowest in the cyst, after drawing a region of interest on the DECT-derived iodine maps. They observed the multi-class area under the curves using the optimal cutoff values with 0.931 for IC_N and 0.918, 0.920 for normalized IC, respectively.
