Multi-modal computer-aided diagnosis systems and methods for prostate cancer
Methods and apparatus for computer-aided prostate condition diagnosis are disclosed. An example computer-aided prostate condition diagnosis apparatus includes a memory to store instructions and a processor. The example processor is to execute the instructions to implement at least a prostate assessor, a lesion assessor, and an outcome generator. The example prostate assessor is to evaluate a volume and density of a prostate gland in an image of a patient to determine a prostate-specific antigen level for the prostate gland. The example lesion assessor is to analyze a lesion on the prostate gland in the image. The example outcome generator is to generate an assessment of prostate gland health based on the prostate-specific antigen level and the analysis of the lesion.
