The obtained value of the accumulation angle of the ultrasound contrast agent is compared with the angle β = 67.5° to diagnose the presence or absence of malignant mass lesion of the peripheral area of the prostate gland. At the value of the angle of accumulation of β≥67.5°, a malignant mass lesion of the peripheral area of the prostate gland is diagnosed. At the value of the accumulation angle of β<67.5°, the absence of malignant mass lesion of the peripheral area of the prostate gland is diagnosed.EFFECT: method provides accuracy and objective differential diagnostics of mass lesions of the peripheral area of the pancreas by creating a new criterion for quantitative estimation of mass lesion perfusion by plotting time-intensity curves and calculating the accumulation angle during CEUS.1 cl, 17 dwg, 1 tbl, 3 ex
