ASIR halves VC dose without drop in image quality
Thanks to a noise-reduction algorithm known as adaptive statistical iterative reconstruction (ASIR), virtual colonoscopy scans acquired at half the normal dose delivered image quality equivalent to standard images, according to a study published in the July issue of the American Journal of Roentgenology.
