MPROVING THE EFFECTIVENESS OF DIAGNOSTICS OF PATIENTS WITH VARIOUS FORMS OF THYROID TUMORS BY USING ULTRASOUND DUPLEX SCANNING WITH CONTRAST MEDIA AND PUNCTURE TECHNIQUES OF FOCAL MASSES

Ultrasound with contrast enhancement (contrast echography) is an intensively developing method of medical imaging. One of the goals of contrast echography is to detect low-speed blood flow (microcirculation) in organs and tissues, pathological neoplasms, which is often impossible with conventional ultrasound.The purpose of the study. To improve the effectiveness of diagnostics of patients with various forms of thyroid tumors by ultra-sound duplex scanning using contrast media and puncture techniques of focal masses.Material and methods. The analysis of characteristic ultrasound signs against the background of sulfur hexafluoride (sulphur hexafluoride) by CEUS in 400 patients was performed. The group included patients with single nodular masses corresponding to stages T1a and T1b C73. In 143 women masses of T1 size were T1b, among 236 men T1a were 8 patients and T1b were 13 patients. The average amount of masses with stage T1a in women amounted to 0,05сbсm, in men 0.05 cbcm; and stage T1b in women was 0.32 cbcm, in men0.8 cbcm. The studied patients were 379 (94.75%) women and 21 (5.25%) men. The average age was 60 years old.Results. Sensitivity=62.2%, specificity=98%, diagnostic accuracy of the method=72.2%Conclusions. Contrast enhancement with the use of sulfur hexafluoride (sulphur hexafluoride) by CEUS method as a method for detecting nodular lesions in combination with the presence of a contrast defect and targeted biopsy under ultrasound control in the area of interest allows with a high probability to establish thyroid cancer at an early stage T1 and increases the accuracy of diagnosis by 10.04%.
