COLOR DOPPLER SONOGRAPHY - AN ADJUNCTIVE TECHNIQUE IN ASSESSMENT OF PARATHYROID ADENOMAS

In evaluating primary parathyroid adenomas with high-resolution color Doppler sonography, initial detection relied on the observation of a h ypoechoic soft tissue mass adjacent to the thyroid gland. Using color Doppler sonography, many adenomas had a demonstrable blood supply from the inferior thyroidal artery branches, identified as a vascular arc surrounding the gland from 90 to 270 degrees. The vascular arc assists the interpreter with establishing the nature of the mass, differentia ting it from masses such as regional lymph nodes, which demonstrate hi lar flow. Sixty-three percent (20 of 32) of parathyroid adenomas had a color arc. The identification of a vascular arc is a useful adjunctiv e finding, improving diagnostic specificity and quickly confirming the diagnosis of parathyroid adenoma.
