What is Prostate MRI?

A prostate MRI provides the clearest, most detailed images of the soft-tissue structures of the prostate, and is used as a screening and diagnostic tool for prostate cancer patients. This test is non-invasive and does not expose you to any radiation.

Prostate MRI is used to:

  • Show if there is any evidence of cancer in the prostate gland if you have a high or rising prostate-specific antigen (PSA) level
  • Evaluate an abscess or infection (prostatitis)
  • Detect an enlarged prostate (benign prostatic hyperplasia)
  • Distinguish between benign and malignant areas
  • Show more clearly the extent of prostate cancer (specifically to see if it is contained within the prostate gland or if it has spread)
  • To help in planning radiotherapy treatment for prostate cancer
  • To find prostate cancer that has grown back after treatment

Zwanger-Pesiri Radiology performs MRI + Ultrasound fused imaging for guiding prostate biopsies, providing a new level of clarity and accuracy. This new technology allows for precise targeting rather than blind sampling, which results in missed cancers and unnecessary needle incisions.

How do I prepare?

Request an appointment online or call us to book your appointment. Once your appointment is booked, your forms will be available on the patient portal.

Notify our staff if you have any metal or medical/mechanical devices in your body. This exam may NOT be performed if you have a cardiac pacemaker, defibrillator, cerebral aneurysm clips or a metallic hearing implant. You must remove all jewelry and any other metallic objects such as hearing aids, jeans with metal zippers, body piercings and removable dental work. Wearing a sweat suit with no metal may prevent you from having to change into a gown.

Additional prep for MRI with I.V. contrast

If you have impaired kidney function, are diabetic or are 70 years of age or older, we will perform an i-STAT creatinine level at the time of your exam to assess your kidney function. It is important to inform us if you are taking the medication hydroxyurea when making your appointment. Keep hydrated before and after your exam.

Bring with you to your appointment:

  • Prescription from your doctor.
  • Current insurance card.
  • Authorization number from your insurance carrier.
  • Any forms you completed at home.
  • Credit card or cash for your insurance co-pay.
  • Any relevant imaging studies that you have from another facility, including the reports. We like to compare the MRI with any previous studies to assist in the diagnostic process.
  • Picture identification.
  • What do I do when I arrive?

    Present your prescription, insurance card and completed forms at the front desk. If any additional forms are required, they will be given to you at this time.

    Be sure to inform the receptionist and technologist if you:

  • Have allergies, specifically to iodine.
  • Have any compromised kidney function or a history of kidney disease.
  • Are pregnant, think you may be pregnant or are breast feeding.
  • Are currently taking any medications.
  • Have any metal or implanted medical device in your body.
  • Have hearing aids
  • Have diabetes.
  • Have asthma.
  • Have any relevant studies from another facility. We like to compare the new MRI/PET study with any previous studies to assist in the diagnostic process.
  • Plan to arrive 15 minutes before your scheduled appointment.

    What happens during the test?

    The MRI technologist will confirm that you are free of all metal both inside and outside your body and review your medical history.

    You will then be brought into the MRI room and asked to lie down on the scanning table. A special light-weight surface coil will be comfortably positioned over your prostate region. The coil maximizes the administration and recording of the radio frequency bursts and the magnetic fields to ensure the clearest possible images.

    The scanning table you are lying on will be moved into the center of the magnet and the test will begin. The machine never touches you. Be sure to remain as still as possible to ensure the best possible images.

    Once all of the images have been recorded, the scanning table will move out of the MRI machine and the technologist will return to assist you off the table.

    The MRI scan can take from 10 to 30 minutes, depending on the area of the body being scanned.

    MRI with I.V. contrast

    If you have impaired kidney function, are diabetic or are 70 years of age or older, we will perform an i-STAT creatinine level at the time of your exam to assess your kidney function. It is important to inform us if you are taking the medication hydroxyurea when making your appointment. Keep hydrated before and after your exam.

    After reviewing your medical history, the nurse or technologist will place the intravenous needle/catheter into a vein in your arm or hand. Then at a specific time in the exam, contrast will be injected into your I.V.

    The first set of images is taken without contrast. Then the dye will be administered and additional images will be taken.

    What happens after the test?

    One of our board certified radiologists interprets your images, compares them to any previous studies and dictates a report which is transcribed, proofread and signed. The report is then faxed and mailed to your referring doctor within one or two days. Your doctor will read the report and review the findings with you.

    All of your signed reports and images are available to your referring doctor on our physician's web portal, and available to you on the patient web portal.
