UroNav: A Powerful New Technology for Prostate Cancer Detection

Physicians affiliated with Memorial Hermann-Texas Medical Center provide leading-edge screening, diagnosis and interventional treatment for prostate cancer. Using the next-generation UroNav fusion biopsy system, they offer high-tech prostate imaging, ensuring men with suspicious prostate lesions more targeted and accurate biopsies.

Magnetic resonance images (MRI) of the prostate can identify suspicious areas within the gland that may require further evaluation. By fusing MRI images of the prostate taken before biopsy with ultrasound-guided images during the biopsy, UroNav provides excellent views of the prostate and suspicious lesions.

UroNav Capabilities

Before UroNav, physicians depended on ultrasound alone to approximate the location for biopsy. Biopsy using MR/ultrasound fusion can:

  • Pinpoint suspicious areas more accurately
  • Reduce the number of tissue samples required during biopsy
  • Reduce the risk of infection, bleeding and pain
  • Shorten recovery after biopsy

 

How UroNav Works

The fusion of MRI and ultrasound images uses electromagnetic tracking, similar to your car’s GPS system. A tiny tracking sensor is attached to a transrectal ultrasound probe that generates a small electromagnetic field, which helps determine the location and orientation of the biopsy needle. A sophisticated algorithm maintains the fusion of MRI and ultrasound images, even during movement.

For Patients Who Require an Annual Biopsy

If the results of your biopsy are inconclusive, your physician might choose watchful waiting over immediate treatment – and recommend an annual biopsy. In addition to more accurately targeting the suspicious area, UroNav saves the image, guiding your physician back to the same place with 3D certainty for future biopsies.

Are You A Candidate For Prostate MRI And MR/Ultrasound Fusion Biopsy?

UroNav is recommended for:

  • Patients with elevated PSA levels greater than 4
  • Negative prior transrectal ultrasound-guided biopsy with continued elevation or rising PSA
  • Positive digital rectal examination with negative transrectal ultrasound-guided biopsy

 

Toward a Cure

Accurate biopsies help improve the prostate cancer cure rate. Recent studies of UroNav have shown positive predictive values above 90 percent.

Finding cancer early means treatment begins early. Contact your physician to schedule your annual prostate examination.
