Prostate Fusion Biopsy

Fusion Biopsy MRIPrior to multiparametric MRI imaging, many men with an elevated PSA or a prostate nodule would head straight for the prostate biopsy procedure. Fortunately, times have changed. Read on and you will understand the importance of obtaining a prostate MRI before proceeding with a prostate biopsy.

WHY A PROSTATE MRI?

The prostate is a very difficult organ to image. The urology community has used the ultrasound for years with moderate success in visualizing abnormalities, but it has always been a challenge to see the minimally suspicious lesions in the prostate. Fortunately, the last 10 years changed all of that. The MRI has become much more powerful, and with that power came the ability to see abnormal areas in the prostate. Read more about the prostate MRI here (insert prostate MRI section) If an abnormal area is seen on the MRI, a fusion biopsy may be just what the doctor ordered.

WHAT IS A FUSION BIOPSY?

Traditionally, men undergoing a regular biopsy will undergo an ultrasound-guided biopsy without the help of a previous MRI. This entails using the ultrasound probe to target multiple areas of the prostate using a 12-zone pattern. If there are abnormal areas in those zones, those will be targeted at that time with the ultrasound. The small specimens are then sent to the pathologist to be evaluated for cancer. People referred to these as “random” biopsies, but they are not truly random as they target specific zones of the prostate. Unfortunately, the ultrasound has limitations and many cancers can be missed with ultrasound guidance alone.

Fusion Biopsy MRIA fusion biopsy incorporates the MRI that has already been completed prior to the patient coming to the clinic. The MRI images are then fused with the live ultrasound images, and a “fused image” is made. This is only possible if an abnormal lesion is found on the MRI. Assuming a lesion is found on the MRI, the fused image is created, and the lesion is marked and targeted in a more precise fashion to evaluate whether the abnormal MRI lesion is cancerous. This can be tricky and depends on the quality of the MRI as well as ensuring the two images have fused together correctly. Dr. Bevan-Thomas has one of the highest experience rates with the technology, dating back to 2012. He currently uses the inVivo and Dynacad platform by Philips.

DOES A FUSION BIOPSY HURT?

Routinely, the local anesthesia takes care of any major discomfort. 2% lidocaine is injected around the prostate to minimize any issues; however, Dr. Bevan-Thomas and Urology Partners currently offer nitrous oxide (i.e., laughing gas) for patients concerned about any pain and anxiety. Although there is an added cost to the patient for the nitrous oxide, many feel it helps with any anxiety that may be associated with the biopsy procedure.

WHAT ARE THE BENEFITS OF A FUSION BIOPSY?

  • Fusion biopsy gives a clear view of the locations that need to be sampled. Dr. B-T can guide the needles precisely to those areas.
  • It’s 30%1 more likely to detect aggressive cancer than a conventional biopsy.
  • The prostate MRI is better at distinguishing between tumors that need to be treated and those that aren’t worrisome. It’s 85% effective at finding intermediate or high-grade cancers.
  • It can reduce the need for later biopsies by giving better information the first time. A more accurate diagnosis helps to clarify the best treatment course.

WHAT ARE THE RISKS AND SIDE EFFECTS OF A FUSION BIOPSY?

Fusion biopsy is well tolerated by most men. As with any procedure, however, there are risks and possible side effects. The most common (although not all) side effects include:

  • Blood in the urine for a couple of days.
  • Bleeding from the rectum. This should be minor and pass quickly.
  • Blood in the semen (in about 50% of men) that may last a few months.
  • Urinary tract or other infection with or without low-grade fever. An antibiotic is given immediately prior to the procedure to minimize this risk.
  • Urinary retention. This is not common, but it’s serious. If you can’t urinate, seek medical attention immediately.

EXPERTISE AND SUPPORT

Dr. Bevan-Thomas brought the MRI and fusion technology to Arlington, Texas, back in 2012 and has been an advocate for MRI imaging for prostate diseases. He reviews the MRI results with each of his patients prior to proceeding with a biopsy, so each of his patients understands the need for his biopsy. He will be sure that you fully understand the procedure, pathology results, and treatment options. So rest easier—we’ve got this!
