DALLAS June 3, 2010 UT Southwestern Medical Center is the first site in North Texas to launch the next generation in CT scanners, which allow doctors to image an entire organ in less than a second or track blood flow through the brain or to a tumor all with less radiation exposure to patients.
Aquilion One dynamic volume computed tomography (CT) can create a detailed 3-D movie of an organ in real time. That makes it particularly useful for quickly diagnosing strokes and heart attacks, for example, where diagnostic speed can be a critical factor in survival and recovery.
Because the machine's technology can take continuous or intermittent images, UT Southwestern radiologists anticipate better visualization in neurology, trauma, whole body, lung, cardiac, vascular and pediatric studies. Other applications include providing distinctive capabilities in orthopaedic and joint studies, diagnosing renal function, and even vocal-cord analysis.
For patients, the new technology can mean less time in a scanner and less exposure to radiation, said Dr. Phil Evans, associate vice president for clinical imaging and professor of radiology.
"Dose has been a concern in the medical literature for a long time and people have been very concerned about it," said Dr. Evans, who directs UT Southwestern's Clinical Imaging Services. "One of the great things about this is that you can do a scan with about half the radiation dose and half the contrast media, so the dose is less and the image is better."
Other scanners piece together strips of images to compile a complete picture, using four-, 16-, 32- or 64-slice machines. Aquilion One, manufactured by Toshiba, exposes patients to less radiation because one strip covers a larger area, therefore requiring fewer swaths overall and less time. The result can be as much as 80 percent less radiation in some cases, according to published research.
Aquilion One uses 320 high-resolution
