New technology fuses MRI, ultrasound to achieve targeted biopsy of prostate cancer

A new prostate-imaging technology that fuses MRI with real-time, three-dimensional ultrasound may offer a more exacting method to obtain biopsy specimens from suspicious areas within the organ.

Four UCLA departments — urology, radiology, pathology and biomedical engineering — collaborated with the medical device company Eigen Inc. to develop and test the technology. The team's early experiences with it are reported in the online May–June issue of Urologic Oncology.

"It's difficult to identify and target suspicious areas using two-dimensional, conventional ultrasound, so urologists currently take samples systematically from the entire prostate," said study author Dr. Leonard Marks, a professor of urology at the David Geffen School of Medicine at UCLA. "The advent of MRI–ultrasound fusion has led to a promising advance in prostate imaging and biopsy targeting.

"Despite the technology revolution of the past several decades, we are still performing prostate biopsies just the same as in the mid-1980s," he said. "We are hopeful that new imaging methods like MRI–ultrasound fusion may soon change that."

According to the American Cancer Society, 230,000 cases of prostate cancer will be diagnosed this year, but not every one of them is deadly. Many small prostate cancers are not serious health threats, and in those cases, surveillance programs can help men avoid radical treatments like surgery. Many smaller cancers grow so slowly that they may never require treatment at all. The new imaging technology could help doctors differentiate the serious cancers from the insignificant.

An MRI scan is a safe and painless test that can provide detailed pictures of organs and other structures inside your body.

The MRI scanner is like a tunnel about 1.5 meters long surrounded by a large circular magnet. You lie on a couch which then slides into the scanner.

Computed tomography of the brain is a non-invasive imaging method that combines x-rays with computer technology. X-ray beams from a variety of angles are used to create a series of detailed cross-sectional images of the brain.

MRI scan is really as simple as before and it's really economic, too.

Great information in this post and I think the advent of MRI–ultrasound fusion has led to a promising advance in prostate imaging and biopsy targeting.
