Application of multiparametric magnet–resonance tomography in diagnosis of clinically significant prostatic cancer
Objective. To estimate diagnostic efficacy of application of multiparametric magnet–resonance tomography (mpMRT) for revealing of clinically significant prostatic cancer.
Маterials and methods. Into the investigation 26 patients with suspicion on presence of prostatic cancer were included. In all the patients a complex clinical examination was conducted, including mpMRT. The images obtained in mpMRT were estimated in accordance to the PI–RADS system (Prostate Imаging–Reporting and Data System).
Results. The tumor was estimated in accordance to the PI–RADS system in 1 point in 2 (7.69%) patients, 2 points – in 5 (19.23%), 3 points – in 8 (30.77%), 4 points – in 6 (23.08%) and 5 points – in 5 (19.23%) patients. In the patients, owing 5 points in accordance to the tumor radiology estimated, the rate of revealing of clinically significant prostatic cancer have constituted 100%. Of a total number 6 patients, owing 4 points in accordance to the tumor radiology estimated, in 5 (83.33%) a clinically significant prostatic cancer was diagnosed, аnd in 1 (16.67%) patient – clinically nonsignificant variant of the tumor. Of a total number 8 patients, owing 3 points in accordance to the tumor radiology estimated, in 4 (66.67%) a clinically significant prostatic cancer was diagnosed, in 1 (16.67%) patient – clinically nonsignificant variant of the tumor, and in 1 (16.67%) – benign prostatic hyperplasia.
Conclusion. Application of mpMRT and a PI–RADS system in 85.7% patients have permitted to reveal a clinically significant prostatic cancer and to escape unnecessary procedures of the puncture biopsy in absence of its radiation features.
