A prostate exam PI-RADS score of 4 is based on a number of imaging tests that indicate prostate cancer may be present and a prostate biopsy is recommended.
The PI-RADS score refers to the Prostate Imaging Reporting and Data System, which assesses the risk of malignancy in prostate disease based primarily on MRI T2WI sequences, diffusion-weighted imaging sequences, and dynamic-enhanced magnetic resonance imaging sequences on a scale of 1 to 5, with a score of 3 or less being mostly benign, and a score of 3 or more being largely malignant.
Therefore, a PI-RADS score of 4 implies a higher likelihood of prostate cancer and requires a prostate biopsy to further determine the presence of malignant prostate lesions.
Patients should go to the hospital for timely examination and treatment under the guidance of their doctors.
