Background: The pathology and prognosis of prostate cancer (PCa) in the peripheral zone (PZ) are worse than transition (TZ), but intra-tumor heterogeneity (ITH) differences between them is unknown.Methods: Preoperative MRI scans were retrospectively acquired PCa patients who underwent radical prostatectomy (RP) from January 2018 to February 2024. PCas classified TZ PZ using RP results as gold standard. Intergrating multimodal imaging data, lesions clustered into different habitat subregions. assessed. model called pre-radical aggressiveness evaluation (PRPAE) evaluate by logistic regression analysis.Findings: study included 236 with a median age 68 years. primary internal validation cohorts consisted 103 25 center A, while an external cohort 108 other two centres. Habitat 1, characterized high cell density complex tissue structure blood flow, was more prevalent PCas, which also exhibited clinicopathological features. And 1 (OR, 2.59; 95%CI: 1.52-4.41; P<0.001) emerged independent risk factor. PRPAE demonstrated performance assessing across all cohorts, AUCs 0.841, 0.769 0.804.Interpretation: Zonal further verified at level. containing HI information had gain efficiency predict aggressiveness.Funding: National Natural Science Foundation China (No. 82220108004); Basic Research Program Shaanxi Province, (2021JZ-25).Declaration Interest: We confirm that there no conflicts interest associated this submission.
