MRI Fusion Prostate Biopsy

MRI ultrasound fusion prostate biopsy is the most effective way to diagnose prostate cancer.

The MRI fusion prostate biopsy is a two-step process. A couple of weeks before the procedure, you will get an MRI of the prostate. MRI of the prostate provides an image of the inside of the prostate. The images are interpreted by a radiologist who will identify areas suspicious for cancer. The images are provided to the urologist, who will then perform the second step, the transrectal ultrasound guided biopsy of the prostate. While the biopsy is performed, the MRI images are fused over the real time ultrasound images for accurate targeting of suspicious lesions. The urologist will obtain the biopsies as identified from the suspicious areas, in addition to the standard 12 core biopsies from the prostate.

Condition it treats:

Prostate cancer

What happens during the procedure:

These appointments are scheduled as outpatient procedures. Typically, the procedures are done in two separate visits.

The first visit requires MRI of the prostate and takes approximately 45 minutes. This procedure does not require sedation.

At the second appointment, the transrectal ultrasound fused biopsy is done. This part of the test requires an outpatient visit to the surgery center. There you will be taken back to a procedure room and given light sedation. You will be positioned on your side so the doctor may obtain the “targeted” biopsies using the MRI images obtained during the first visit. The images are superimposed on a monitor screen to guide where the biopsy should be taken. An additional standard core biopsy may also be obtained. When the procedure is complete, you are taken into a recovery area. When stable, you will be discharged home. You will need a driver to get you home.


  • Provides clear, more accurate information than a standard biopsy
  • Detects prostate cancer

The UroNav Fusion Biopsy System fuses pre-biopsy MR images of the prostate with ultrasound-guided biopsy images in real time, for accurate delineation of the prostate and suspicious lesions, as well as clear visualization of the biopsy needle.
