title: [Ultrasonic examinations of thyroid newgrowths].
abstract: The results of complex ultrasonic, histological and cytological examination of 148 patients with newgrowths thyroid were analyzed. Grey-scale mode, colored and energy Doppler scanning, three-dimensional reconstruction of vessels were used. A new classification of nodular vascular pattern types based on 3-D reconstruction is proposed. The majority of malignant formations were characterized by perinodular hypervascularization and internodular hypovascularization (82.4%), adenomas--by peri- and intranodular hypervascularization (88.9%), colloid nodes--by perinodular hypervascularization (85.5%), the blood flow was absent in simple cysts (85.3%). It was established that complex of these methods increases informative value of ultrasonic examination in diagnosis of thyroid nodular diseases: in malignant neoplasms the sensitivity is 92.9%, specificity--86.1%, diagnostic accuracy--86.9%, in adenomas--93.4%, 79.2% and 82%, in colloid nodes--75.7%, 84.1% and 79.8%, respectively. In cystic masses diagnostic value of Doppler methods didn't change: sensitivity was 90.4%, specificity--63%, diagnostic accuracy--80.5%. The combined ultrasonic examination provides a differential approach to treatment of patients with thyroid nodular masses and decreases the number of unjustified surgical interventions.
