Prostate MRI

Are you a candidate for prostate MRI?

You should always speak to your primary care physician or urologist if you believe you could benefit from a prostate MRI and/or MR-guided prostate biopsy. Below is the primary criteria used to determine whether a patient is a candidate for prostate MRI:

• Patients with negative prior transrectal ultrasound-guided (TRUS) biopsy and continued elevated prostate-specific antigen (PSA) level.
• Patients with positive digital rectal examination (DRE) and a negative transrectal ultrasound-guided TRUS biopsy.
• Patients requiring prostate surgery or radiation therapy.

What to Expect – Step 1

Step 1: MR Imaging

Prostate MRI is a noninvasive imaging technique that does not require exposure to ionizing radiation.

• An IV will be started to administer contrast.
• A Multiparametric MRI is performed and Computer Aided Detection (CAD) is used to help the radiologist identify prostate cancer.
• The entire exam is usually completed in 45-60 minutes.

Step 2: MR-Guided Biopsy

Overlake Medical Center is the first facility in the Seattle area to offer MR-guided biopsy of the prostate. A prostate biopsy is a minimally invasive technique where small tissue samples are taken from the prostate for microscopic evaluation by a pathologist.

• Conscious sedation is administered through an IV for the patient’s comfort.
• An MRI-compatible needle sleeve is gently placed 3 to 4 inches into the rectum.
• MRI technology is used to precisely guide the biopsy needle and samples previously identified by the Multiparametric MRI and samples are taken from the target area previously identified by the Multiparametric MRI.
• The entire procedure will take about one hour.
