Evaluation of through-time radial GRAPPA for functional cardiac imaging in a patient population

Abstract

Background Real-time cardiac imaging with through-time radial GRAPPA has been shown to yield high quality functional images [Seiberlich, et al. MRM2011 Feb;65(2):492-505]. The goal of this work is to evaluate through-time radial GRAPPA in terms of overall scan time, quantitative measures of ESV, EDV, and EF, and image quality in a patient population.
