METHOD OF DIFFERENTIA DIAGNOSTICS OF PROSTATE GLAND CANCER Russian patent published in 2009 - IPC A61B8/06 

FIELD: medicine.

SUBSTANCE: invention relates to field of medicine, namely, to urology. Laser Doppler ultrasonography, in which probe-sensor is installed in point of prostate gland projection perpendicular to perineum skin. Dopplerogram is decomposed into harmonic constituents, index of microcirculation (I) is calculated by formula: , where M is index of microcirculation in perfusion units, α - mean-square deviation, A_max - maximal amplitude in each group of fluctuations of amplitude-frequency spectrum; F_max - maximal frequency in each group of fluctuations; α - slow rhythms 1-3 cycles per a minute, LF - slow rhythms 4-12 cycles a minute, HF - fast rhythms 12-36 per minute; CF - pulse fluctuations. If microcirculation index is less than 0.433 malignant neoplasm of prostate gland is diagnosed, if index of microcirculation is larger than 0.433, benign hyperplasia is diagnosed.

EFFECT: extension of arsenal of means for differential diagnostics of prostate gland cancer.
