✦ Synopsis
In a prospective study, we assessed the possibility of recognizing autonomous adenomas of the thyroid with color-coded image-directed Doppler sonography using internal hypervascularization in thyroid nodules for identification. Fifty-three patients with thyroid nodules underwent additional CCDS examination and nuclear scintigraphy (reference). Of 29 patients having autonomous adenomas, 28 patients presented internal hypervascularization in their nodules resulting in a sensitivity of 96% and a specificity was 75%. Interestingly CCDS detected six adenomas in patients showing normal laboratory data (bTSH, TT 3 , FT 4 ). CCDS could be used to exclude focal adenomas with a negative predictive value of 94%. The positive predictive value for adenoma was 82%.
