Published Workflows
Objective: Evaluate the role and accuracy of biparametric MRI in patients with prostate cancer for diagnosis, extent assessment, and post-treatment early recurrence monitoring.
Why it works: The study evaluates MRI sequence findings in lesions that were later pathologically confirmed as prostate cancer, using pathology as the reference to assess how often specific MRI features are present in malignant lesions.

Implementation Constraints
cofactor dependency: cofactor requirement unknownencoding mode: genetically encodedimplementation constraint: context specific validationoperating role: sensor
This requires MRI diffusion imaging and generation or interpretation of ADC maps. The study uses pathology-confirmed cancer cases as the reference set.; requires MRI diffusion acquisition and ADC map generation
The abstract does not provide a standalone ADC accuracy estimate or define thresholds for interpretation. It also does not compare ADC-based assessment directly with mpMRI.; abstract reports ADC maps together with DWI rather than as a separate performance result
