GE Medical Systems has received Food and Drug Administration clearance for its CT colonography technique. When used on GE's LightSpeed Ultra eight-slice CT scanner, colon exams are 50% faster than on the company's four-slice systems, according to GE of Waukesha, WI.
With the eight-slice system, the entire abdomen can be scanned in 10 to 20 seconds, allowing doctors to immediately see views of the colon from both the supine and prone positions, while also offering easier detection of the size and location of polyps and lesions, according to GE.
The technique will allow physicians to study the inside and outside of the colon, view the wall of the colon using volume rendering, view three oblique images of the area along with the endoluminal view, and mark areas of interest. This will enable physicians to navigate the area in different planes simultaneously, according to the company. CT colonography is available on LightSpeed four- and eight-slice systems.
