In addition to providing better spatial resolution, multi-detector CT scanners are significantly faster, resulting in shorter breath-hold requirements, reduced motion artifacts, and decreased contrast volume requirements when compared with single-detector-row helical scanners or conventional nonhelical scanners.Thursday, 18 Jan 2007 12:04:16 GMT
