METHOD FOR DIFFERENTIAL DIAGNOSTICS OF SPLEEN FOCAL DISEASES Russian patent published in 2017 - IPC A61B8/08 A61B5/00 

FIELD: medicine.

SUBSTANCE: ultrasound examination of the spleen is performed in B-mode with detection of a pathological focus. The border, the radius of the focus, perifocal zone, unchanged pulp of the spleen are determined. The focus radius is extended from the visible focus border to the focus radius length and the resulting line is divided into 6 equal segments. Shear waves elastography is performed at the points of line division, having designated them from the middle, as: 0C, 1C, 2C, 3C, 4C, 5, C6. The derived rigidity values are compared. If the 0C, 1C, 2C, 3C values differ by no more than 20%, and the values at points 4C, 5C, 6C are less than 20-30% each, the focus is attributed to lymphocytic infiltration in case of lymphogranulomatosis or chronic leukemia. If the values of 0C, 1C, 2C, 3C differ by no more than 20% and more than 4C, 5C and 6C by 30%, and the values at points 4C, 5C, 6C differ by no more than 20-30%, the focus is attributed to metastases in the spleen or to focal lymphosarcoma.

EFFECT: increased accuracy of focal lesions diagnosis in the spleen.
