Current CT scanners provide ‘bewildering array’ of options

Facebook X LinkedIn Email
In a review of volume CT, Dr. Frank John Parrish from MIA Victoria in Malvern, Australia, noted that the first CT scanner, which appeared in the 1970s, could take one slice every two seconds. Now, volume-CT scanners can take 192 slices per second, and even faster scanners are undergoing clinical evaluation. Multislice volume scanners have reduced the relatively high radiation doses associated with thin slices. Although thin slices require higher radiation doses than thick slices, several studies have shown that they can reveal more disease characteristics. Still, on a case-by-case basis,...Read full article
