Michael M. Lell, M.D.

We sought to evaluate the image quality of iterative reconstruction in image space (IRIS) in half-dose (HD) datasets compared with full-dose (FD) and HD filtered back projection (FBP) reconstruction in abdominal CT. Read more

To prospectively compare traditional filtered back projection (FBP) and iterative image reconstruction for the evaluation of heavily calcified arteries with coronary CTA. Read more

Comparison of Statistical Iterative and Filtered Back Projection Image Reconstruction Techniques for the CT Assessment of Coronary Artery Stents

Iterative image reconstruction techniques incrementally improve the assessment of coronary artery stents by reducing image noise and beam-hardening artifacts. Read more

Comparison of Iterative and Filtered Back Projection Image Reconstruction Techniques for the Evaluation of Heavily Calcified Vessels with Coronary CT Angiography

U. Joseph Schoepf, M.D.

Iterative image reconstruction techniques appear superior to FBP for the evaluation of heavily calcified vessels with cCTA and should be preferentially used in patients with high calcium scores. Read more

IRIS effect on calcium blooming artifact

posted by Stephan Achenbach, M.D. | May 26, 2010
Stephan Achenbach, M.D.

Does iterative reconstruction in general and IRIS specifically decreased blooming artifact from calcific plaque in coronary cta and to what extent. Is there a difference between the benefits derived from IRIS between its use with the Definition scanner versus the Flash? Read more
