The Department of Radiology at UHC is the first in the world to use GE's RapidScreen Digital, a new digital computer-aided detection (CAD) device for x-ray detection of lung cancer. UHC is the clinical test site for the innovative technology, and applies it to the 160,000 chest X-rays performed each year. At the heart of RapidScreen Digital is a sophisticated post-processing algorithm that analyzes the digital x-ray data and draws circles around suspicious regions of interest. The new CAD system, also used for mammography at UHC, focuses the attention of radiologists on these potential abnormalities.
"As a tertiary care center, we see a lot of complex cases," says Dr. Robert Gilkeson, assistant professor of radiology and director of cardiothoracic imaging at UHC and Case Western Reserve University School of Medicine. "RapidScreen allows us to make significant improvements in detecting lung cancer. UHC has a very large cancer patient population with a significant amount of chest disease. This technology will be very helpful in evaluating those patients."
Dr. Gilkeson and his team are using the new CAD system in conjunction with another advancement in digital X-ray technology called "dual energy subtraction." The radiologist can literally erase bones from the image to study the soft tissue normally hidden by the ribs and sternum. According to a thoracic imaging study published in Radiology in January (Volume 226, Number 1), more than 90% of lung cancers that are missed today
