METHOD FOR VISUALIZING EFFICIENCY OF TREATMENT OF BENIGN PROSTATIC HYPERPLASIA Russian patent published in 2019 - IPC A61B5/55 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to oncology, urology and radiation diagnosis, and can be used to visualize the effectiveness of the treatment of benign prostatic hyperplasia. Multiparametric magnetic resonance imaging of the pelvic organs with the addition of a 3D-Cube three-dimensional pulse sequence is performed. Resulting MP data is processed at the GEAW 4.7 VolumeShare7 workstation in the reformat and readyview programs. Prostate gland, urethra, seminal vesicles, peripheral and transitional zones with nodosity of adenomatous hyperplasia are isolated in layers, depending on location thereof, each of which is cut into a separate shape and stored as a model in the STL format. Resulting models in real volume are then combined on a personal computer in the Meshlab 2016 program into a single model. In the final 3D model, the prostate gland is labeled transparent, the urethra and the seminal vesicles in white, the nodes of benign prostatic hyperplasia are labeled as follows: hyperplasia of the lateral lobes – green, retrourethral lobe – yellow, peduncular, pedicle, nodes – blue, retrotrigonal zone – red. This model is saved and used as a visual three-dimensional image of the volume, size and localization of the nodes of hyperplasia. Distance from any part of the urethra, capsule, apex, base, anterior section of the prostate gland to the hyperplasia site is measured. Based on visual analysis, models are compared before and after different types of division.

EFFECT: method ensures the creation of a universal, understandable for both a specialist doctor and a patient informed about his disease, a three-dimensional model of the prostate gland with the release of the anatomical areas of the transient zone, which is the source of BPH, through magnetic resonance imaging.
