BALTIMORE, Oct. 10, 2019 /PRNewswire-PRWeb/ -- The
Urology Specialists of Maryland at
Mercy Medical Center now offers patients MRI TRUS Fusion Biopsy, a
new method to biopsy suspected prostate tumors by fusing MRI images
of the gland with information gathered through transrectal
According to Dr. Blaine Kristo,
medical director of the Urology center, the procedure serves to
identify clinically significant, high-grade tumors in the
"Ultrasound-guided biopsy has been the current standard of care
for confirming prostate cancer. However, ultrasound alone doesn't
provide the resolution necessary to distinguish cancer, especially
very small lesions, from healthy tissue-- hence the need for
biopsy, where more than 20 needles may be needed to identify a
tumor. In addition, ultrasound targets the gland's peripheral
areas, meaning you may miss some cancers located in the front,
middle and top portions of it," Dr. Kristo explained.
With the MRI/TRUS fusion technique, patients with an elevated
PSA (Prostate Specific Antigen) value first undergo an MRI scan of
the prostate, which is much more effective in revealing details in
soft tissue. Radiologists then review the scans and identify
"This is followed by an ultrasound probe to examine the
prostate. Special software is used to overlay the MRI images,
providing fine-grained detailed, 3-dimensional views of the gland.
These fused images help guide the physician in placing biopsy
needles with great precision, guiding the needle directly to areas
that look suspicious on MRI, down to the millimeter. Biopsies are
mapped, targeted and tracked in an outpatient procedure under local
anesthesia that typically takes about 20 minutes," said Dr.
Brad Cogan, Chair of the Department
of Radiology at Mercy.
Dr. Cogan noted that this technique may improve cancer detection
rates by 10 to 15 percent, and according to some research, as much
as 60 percent.
The MRI/TRUS fusion biopsy is a "particularly good option," Dr.
Kristo said, for patients who:
Have elevated PSA levels and are considering biopsy
Are due for a repeat prostate biopsy for possible prostate
Have elevated or rising PSA levels despite previous negative
Are under active surveillance for prostate cancer
"The fusion biopsy approach helps reduce the number of repeat
biopsies for men who have fluctuating PSA values or have small,
slow-growing lesions who are in a state of 'watchful waiting,'" Dr.
