Abstract

The invention provides a system for partitioning of a prostate gland and zoning and dissection of seminal vesicles for mpMRI. The system comprises an AI scheduler module, wherein the AI scheduler module is used for extracting header file information from a DICOM image, judging a type of each sequence in the image and searching prostate gland and seminal vesicle dissection and partitioning modulesand prostate gland and seminal vesicle focus auxiliary-diagnosis modules matched with types of sequences; the prostate gland and seminal vesicle dissection and partitioning modules, which are used forreceiving a T2WI sequence, an ADC sequence, a DCE sequence and a T1WI sequence, partitioning a prostate gland from bilateral seminal vesicle glands and partitioning the prostate gland into an outer periphery zone, a transitional zone, a central zone, a front fiber matrix zone and a urinary tract; and all the prostate gland and seminal vesicle focus auxiliary-diagnosis modules, which are used forreceiving sequences and partitioned data matched with corresponding prostate gland and seminal vesicle focus auxiliary-diagnosis modules and outputting and feeding back diagnostic data to a structuring reporter module. The invention further discloses a method for partitioning of the prostate gland and zoning and dissection of the seminal vesicles for the mpMRI. The system and the method are beneficial to diagnosis and positioning of a prostatic cancer and detection on extracapsular invasion and seminal vesicle invasion and can be applied to positioning of benign pathological changes of the prostate gland and the seminal vesicles.

Description

technical field [0001] The invention relates to the field of medical information, more specifically, to a system and method for segmenting the prostate and seminal vesicles on mpMRI. Background technique [0002] Multiparametric Magnetic Resonance Imaging (mpMRI) is an important imaging method for pre-puncture diagnosis of prostate cancer, which can be used to detect clinically significant cancer and guide biopsy. When making a diagnosis using mpMRI, the prostate gland should be divided into divisions. The PI-RADS guidelines clearly stated that the T2WI sequence images should be divided into four regions: the anterior fibrous matrix zone, the transition zone, the peripheral zone and the central zone, plus the urethra, and the prostate gland should be divided into at least 5 zones; The lateral seminal vesicles are also divided into 2 divisions. [0003] The detection of clinically significant prostate cancer was mainly detected by ADC sequence, the early detection of prosta...
