Exploring the Correlation Between MRI Image Characteristics and Diagnosis, Pathology and Prognosis in Patients With Prostate Lesions

This study aims to use time-dependent DWI (td-DWI) to fit and calculate quantitative information such as cellularity, cell diameter, intracellular volume fraction and cell density; use the chemical exchange saturation transfer (CEST) sequence to saturate hydrogen protons (hydroxyl (-OH), amide (-NH) and amine (-NH2) groups) in specific metabolites in the body by applying frequency-selective saturation pulses to non-invasively reflect metabolic information in the human body for the diagnosis of prostate cancer and to evaluate its diagnostic accuracy compared with traditional multi-parameter magnetic resonance imaging.
