New research confirms that an innovative procedure combining MRI and ultrasound to create a 3D image of the prostate can more accurately locate suspicious areas and help diagnose whether it’s prostate cancer.
Using specialized equipment needed, physicians at UT Southwestern Medical Center’s Harold C. Simmons Comprehensive Cancer Center began using the fusion biopsy procedure about three years ago for its ability to blend live ultrasound images with captured MRI images.
The fused image creates the 3D model, and flags anomalies that could be areas of concern. That helps guide urologists to get tissue samples called biopsies to determine whether cancer is present.
UT Southwestern’s early adoption of the cutting-edge technology allowed researchers to report on the superior diagnostic performance of this novel approach compared to traditional methods for diagnosing prostate cancer. Furthermore, these researchers have partnered with colleagues in Brazil to conduct follow up studies that now show the technique consistently improved detection of clinically significant prostate cancer under a wide variety of conditions, even when radiologists were using different equipment and protocols.
“In the past, we diagnosed prostate cancer by random biopsies of the prostate in men with elevated PSA values. With fusion biopsy, we actually find more cancer, we can differentiate between dangerous tumors and less aggressive tumors, and in some cases we perform fewer biopsies,” said Dr. Daniel Costa, Assistant Professor of Radiology and with the Advanced Imaging Research Center (AIRC) at UT Southwestern.
