The review presents the capacities of Doppler ultrasound study in the differential diagnosis and management of thyroid nodular masses. The problem of goiter does not presently lose its urgency. Palpable thyroid nodular masses are detectable in 4-7% of the worlds population [3, 4, 25] and the detection rate of thyroid abnormalities via radiation studies is 20 to 50% [4, 5]. Complex ultrasonography (USG) increases the obtained volume of information and its clinical value in nodular goiter. Examination of blood circulation in the thyroid and nodular masses involves two-dimensional gray-scale echography, color Doppler coding and Doppler spectrum analysis. The present Doppler study with color Doppler coding makes it possible to unify an assessment of the distribution of color flow maps in the vessels of nodular masses. Doppler spectrum analysis in nodular masses can confirm the enhanced blood flow in nodular tissue as compared with that in the intact parenchyma (increased linear blood flow velocities in the intranodular and/or perinodular arteries as compared with those in the adjacent tissue arteries). Doppler USG introduced early after thyroid surgery provides objective information on the area operated on and evaluates the course of its wound process, diagnoses early postoperative complications, and defines the adequacy of performed surgical intervention [1, 3, 7].
