Abstract

We intended to compare gray-scale vs. color Doppler ultrasound findings in cold thyroid nodules. Sixty-four patients with cold thyroid nodules for whom the presumptive diagnosis of malignancy (based on isotope scan study) had been made were consecutively included. They underwent gray-scale and color Doppler sonography studies. Based on histopathologic examination of surgically removed nodules, there were respectively 25 (39) and 39 (61) malignant and benign nodules. On color Doppler sonography, preference central hypervascularity was the most common finding in malignant nodules (17 nodules, 68). Among benign nodules, preference perinodular hypervascularity was the most common finding (26 nodules, 66.7). The most sensitive and specific Doppler sonography findings for malignant nodules were preference central hypervascularity (68) and only central vascularity (97), respectively. On gray-scale sonography, absent halo sign was the most common finding in malignant nodules (20 nodules, 80). Among benign nodules, microcalcification was the most common finding which was reported in 12 nodules (30.7). Hypoechogenicity was the most specific finding (76.9) for malignant nodules. Since both gray-scale and color Doppler ultrasonography are inexpensive, non-invasive, and accessible methods to diagnose thyroid malignant cold nodules, it is recommended that these methods be applied by clinicians to assist or even substitute other invasive methods.
