PHILADELPHIAWhat began as single-slice CT scanning has now evolved into dynamic volume scanning, utilizing as many as 320 detectors. The possibilities for wide-area detector technology include consistently low radiation exposure for coronary CT angiography (CCTA), as well as myocardial perfusion imaging, kinetic opacification slopes that distinguish between normal and diseased arteries and vascular profiling, according to Frank Rybicki, MD, PhD, who spoke July 21 at the annual meeting of the American Association of Physicists in Medicine (AAPM).
