Radiologists adjusting to revolution in CT.

CHICAGO—The emergence of 64-slice computed tomography (CT) is shaping up to be more than simply the next stage in the evolution of noninvasive diagnostic imaging. Radiologists are viewing it as a revolution, opening the possibilities of images neither they nor referring physicians have yet considered. However, revolutions overturn the status quo and create states of chaos. For the imaging community, that means that many radiologists may not be up to speed with the capabilities of 64slice CT and therefore may be missing diagnostic opportunities. The 64-slice CT, approved by the US Food and Drug Administration in 2004, offers faster scan times, thinner CT sections, improved temporal resolution, and the opportunity for volume imaging. The shorter scan times enable CT scanners to capture high-quality “motion-free” images of the beating heart and coronary arteries, which in the past was not possible due to the longer scan times of older CT scanners (Leschka S et al. Eur Heart J. 2005;26:14821487). Thinner slicing (0.5-mm) and improved spatial resolution should lead to better “virtual colonoscopy,” which will detect smaller polyps. The technology also opens other parts of the body to noninvasive examination.
