3D Ultrasound MRI Fusion Biopsy - How It Works

What You Can Expect

If your urologist determines that you are a good candidate for the 3D Ultrasound/MRI Fusion biopsy, there are several steps to this diagnostic procedure. 


  • You will be scheduled for and undergo an MRI of the prostate with our radiology partner, RadNet.

  • Radiologists who are specially trained in this MRI imaging review the images, identify suspicious lesions and build a 3D image of the prostate and each lesion.

  • You will then be scheduled for a separate appointment where your 3D ultrasound and biopsy will be performed in one of Chesapeake Urology’s Summit Ambulatory Surgical Centers.

The 3D Ultrasound and Prostate Biopsy

  • One of Chesapeake Urology’s specially-trained urologists will perform the 3D ultrasound to build a live image of your prostate.

  • Your urologist will then overlay or merge your previous MRI onto the live 3D ultrasound image to create an enhanced 3D map of the prostate, allowing your urologist to determine the exact location of potential tumors.

  • After the ultrasound, you will be given general anesthesia as your urologist performs the targeted prostate biopsy utilizing the combined MRI and 3D ultrasound images as a guide to the exact location of the suspicious prostate tumor(s).  

  • Each biopsy track is memorized by the computer software so that your urologist can retrace his or her steps if a second biopsy is necessary in a particular location.  Additional biopsies may also be taken in order to map the entire prostate gland.

  • After the biopsy, you will be taken to recovery before you are able to return home.

  • You should receive the results of your biopsy in about one week.

3D Ultrasound/MRI Fusion Biopsy vs. 2D Transrectal Ultrasound (TRUS)-Guided Biopsy

Currently, the standard diagnostic tool for detecting prostate cancer is 2D (2 Dimensional) Transrectal Ultrasound (TRUS)-guided biopsy.

  • A small probe is inserted into the rectum to obtain images of the prostate.

  • A biopsy needle is then inserted into the probe to obtain random tissue samples of the prostate gland in order to determine the presence of prostate cancer cells.

3D Ultrasound/MRI Fusion Biopsy

  • After your MRI and 3D ultrasounds are performed, a specially trained urologist overlays the two images to get a precise picture and location of prostate tumors.

  • A biopsy needle is then guided to the exact location of identified lesions or tumors in your prostate.

  • Rather than collecting random tissue samples, this advanced biopsy collects cells from an identified tumor within the prostate for the most accurate diagnosis.


Benefits of the 3D Ultrasound/MRI Fusion Biopsy System 

In addition to providing more accurate, enhanced diagnosis for prostate cancer and subsequently, more targeted therapies,  the 3D Ultrasound/MRI Fusion Biopsy system:

  • Identifies and locates hidden tumors missed by traditional biopsies, especially localized prostate tumors that can be difficult to image

  • Enhances visualization of tumors within the prostate, detailing exact size and location of suspicious tissue and tumors

  • Allows for targeted biopsies and improved sampling for a more accurate diagnosis

  • Provides more accurate staging and diagnosis because of the fusion of live 3D Ultrasound and MRI images

  • Allows for the development of  a more targeted, individualized prostate cancer treatment and management plan   

  • Can benefit men prescribed watchful waiting or active surveillance for suspected prostate tumors, those with rising and elevated PSAs and negative biopsies, and those men with biopsies that show abnormalities


A Distinct Diagnostic Advantage for Our Patients

Studies show where conventional TRUS-guided prostate biopsies fail to provide a clear and precise visualization of prostate tumors, this new, computer-assisted 3D MRI/Ultrasound Fusion Biopsy provides Chesapeake Urology patients with a distinct advantage which can provide a more optimal outcome.

Ask your doctor about the 3D MRI/Ultrasound Fusion Biopsy for prostate cancer and if it is right for you.
