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].

The diagnostic significance of the color Doppler study of testicular blood flow in testicular torsion has been studied for about 40 years, however, the prognostic value of the results obtained is ambiguous, as are the actual imaging capabilities of the technique. Our own experience of 110 observations of testicular torsion in children older than the neonatal period allows us to draw statistically reliable conclusions. Made on equipment premium-class research made it possible to evaluate how visualization intratesticular vascular pattern, and whirpool-sign and submit the primitive model of the actual inversion, explaining the impossibility of rendering whirpool-sign with the greatest tight inversion. The dynamics of testicular blood flow was studied immediately after successful and unsuccessful manual detorsion and in the long term after operative detorsion and orchopexy. The publication contains a brief analysis of the literature and is extensively illustrated.
