High-Definition CT System Uses Less Radiation

A high-definition computed tomography (CT) has been developed to provide an improved image with less radiation dose per scanned patient. This new technology uses up to 83% less radiation on cardiac scans and up to 50% less across the rest of the body.

The new GE Healthcare (Chalfont St. Giles, UK) Discovery CT750 scanner gives clinicians greater diagnostic confidence through high-definition- (HD)-quality imaging with 33% greater clarity and allows physicians to see small vessels, as thin as a human hair, from head to toe. The CT750 also provides clinicians with minimized image distortion, the ability to accurately analyze masses and lesions regardless of their location, and the capability to isolate problems for precise treatment planning.

Dr. James Min, a cardiologist at New York-Presbyterian Hospital (New York, NY, USA) and assistant professor of Medicine at Weill Medical College of Cornell University (New York, NY, USA) said, "A coronary CT scan provides exquisite pictures of the heart and enables doctors to get inside the arteries noninvasively to see the level of plaque and blockage with incredible accuracy and speed. Some believe that this is how to stop a heart attack before it happens. The Discovery CT750 is poised to become the most accurate and cost-effective diagnostic tool we have in the detection of coronary artery disease. While this may be overly optimistic, through the CT scan, we can shift from imaging for intervention to imaging for prevention.”
