Better Identification of Prostate Cancer
CHICAGO --(Business Wire)--
Prostate cancer can be detected simply and more accurately with a
radiation-free, non-invasive screening test, according to findings
announced today at an international physician conference.
The findings, reported at the International Contrast Ultrasound Society
(ICUS) annual conference, found contrast-enhanced ultrasound imaging
(CEUS) exams can provide more accurate results than either MRI, PSA or
conventional ultrasound imaging.
"The accuracy of MRI in diagnosis is very limited and it misses a
significant number of cancerous tumors," according to Hessel Wijkstra,
Ph.D., a professor at Eindhoven University of Technology and a research
scientist at AMC University Hospital in Amsterdam in the Netherlands.
"In addition, PSA testing is inaccurate and generates large numbers of
false negatives and false positives," he added.
Prostate cancer is the number one cancer in men, and the potential
impact of this is hue for male patients, according to Wijkstra.
"CEUS is less expensive, more accurate, more accessible and does not use
radiation," added Stephanie Wilson, a radiologist from the University of
Calgary and Co-President of ICUS.
Wijkstra said that the lack of accuracy in the localization of prostate
cancer limits patients to radical treatment options, such as operations
and the use of radiation. "These treatments can have serious side
effects, including impotence, incontinence, and a debilitating effect on
the patient's quality of life," he added.
While the ultrasound contrast agents Definity (Lantheus Medical Imaging)
and Optison (GE Healthcare) are only approved for use in the United
States for cardiac imaging, they and other agents are used widely in
Europe and elsewhere for imaging tumors and organ systems throughout the
body. Additional applications of these ultrasound contrast agents are
under review worldwide.
ABOUT ICUS: ICUS is an international, multi-disciplinary, not-for-profit
medical society that is exclusively dedicated to advancing the use of
contrast enhanced ultrasound diagnostic imaging to improve patient care
worldwide. Founded in September 2008, ICUS brings together physicians,
scientists, and other ultrasound imaging professionals from over 55
countries. ICUS members represent diverse specialties such as
cardiology, radiology, vascular imaging, gastro-intestinal imaging,
oncology, OB-GYN, and hepatology. For more information about ICUS,
