MRI Scan for Prostate Cancer: What to Know

The scan uses magnetic fields and radio waves rather than X-rays. Images can show the prostate, nearby tissues, and sometimes lymph nodes or bone areas that need closer assessment. An MRI finding is not the same as a cancer diagnosis; a clinician combines it with symptoms, examination, PSA results, and sometimes a biopsy.

Tell the imaging team about metal implants, a pacemaker, kidney problems, allergies, or possible pregnancy. Follow the centre's instructions about eating, drinking, and bladder or bowel preparation. During the scan, lie still while the table moves into the scanner. Some examinations use contrast through a vein. Ask how and when your report will be shared, and whether a targeted biopsy or another test is being considered.

Contact a clinician promptly for inability to pass urine, worsening difficulty passing urine, fever with urinary symptoms, visible blood in urine, or severe new pelvic or back pain. These symptoms need assessment because they can reflect problems requiring treatment, whether or not cancer is present.

Ask what question the MRI is intended to answer, whether contrast is planned, how your PSA and examination affect the interpretation, and what the next step would be if an area looks suspicious.
