DSCT compares full- to half-dose VC by patient
By Eric Barnes
Mayo Clinic researchers used iterative reconstruction to acquire half-dose virtual colonoscopy exams with dual-source CT (DSCT) and compare them to full-dose exams without scanning patients twice. The technique offers a more accurate way to compare dose levels between different CT protocols, according to a new study in the Journal of Computer Assisted Tomography.
