Abstract
The aim of the study was to determine the opportunities of multiparametric ultrasound in the early detection of papillary thyroid cancer. Examination results of 258 patients with papillary thyroid cancer at the stage of preoperative preparation were analyzed. All patients underwent multiparametric ultrasound examination in grey-scale mode, in color Doppler mapping mode, in compression elastography mode and shear wave elastography, ultrasound with contrast enhancement. In papillary thyroid cancer, "cold" tones prevailed. the velocity of the shear wave was 4.61±1.33 m/s (95% CI), Young's modulus was 63.3±14.7 kPa (95% CI), the elasticity index (strain ratio) was 4.89±1.65 (95% CI) c.u. When assessing the qualitative parameters of ultrasound with contrast enhancement, it was noted that in papillary thyroid cancer, heterogeneous accumulation of ultrasound contrast agent prevailed (54.5%), there was a more pronounced intensive accumulation of ultrasound contrast agent (63.6%). when measuring TPI, the EC indicator was 20.64±4.37 s, PI – 31.08±1.65 dB, PI (DT/2) – 64.00±10.27 s. Thus, the study showed that the complex use of multiparametric ultrasound examination techniques (B-mode, color Doppler mapping, compression elastography, shear wave elastography, ultrasound with contrast enhancement) is highly informative and should be used in the differential diagnosis of papillary thyroid cancer in the preoperative assessment.
