MRI Technology: The new option for prostate diagnosis and treatment
At Overlake Medical Imaging, we use Multiparametric Magnetic Resonance Imaging (MRI) as a new option for detecting and locating prostate cancer in men with abnormal PSA levels.
A diagnostic MRI creates a detailed cross-sectional image of the prostate and surrounding tissues. The image is examined by one of our board certified radiologists. Tissue samples of suspicious areas may be obtained for further evaluation by conducting a targeted Trans-Rectal Interventional MR (magnetic resonance) –guided (TRIM) biopsy procedure.
Did You Know?
- One in six men will be diagnosed with prostate cancer during his lifetime, however not all prostate cancer requires immediate surgical treatment.
- MRI is the most effective test to identify significant disease and to guide therapy.
- Prostate cancer is the most common form of cancer other than skin cancer in American men, according to the American Cancer Society.
- Prostate cancer is the second leading cause of cancer death in men behind lung cancer.
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 – the two step process
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 30 to 45 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 are taken from the target area.
- The entire procedure will take about one hour.
One of our board certified radiologists will interpret your images and send your referring provider a written report and pictures detailing the findings of your exam. Your provider will go over your results with you.
