ASIR technique reduces radiation from CT angiography

AUGUST 20, 2010 | Reed Miller

Vancouver, BC - Adaptive statistical iterative reconstruction (ASIR, GE Healthcare), an addition to the growing list of techniques for reducing radiation exposure from computed tomography (CT), has been validated in a large clinical trial [1].

Results of the Estimated Radiation Dose of Coronary CT Angiography Using Adaptive Statistical Iterative Reconstruction (ERASIR) study are published in the September 2010 issue of the American Journal of Roentgenology. Dr Jonathon Leipsic (University of British Columbia, Vancouver) prospectively evaluated 574 patients undergoing CT-angiography (CTA) at three centers, comparing CTA images created with ASIR (n=331) and CTA images created with the standard filtered back projection (FBP) (n=331) technique...
