Research findings, 'Fast four-dimensional coronary MR angiography with k-t GRAPPA,' are discussed in a new report. Researchers in the United States conducted a study "To investigate the effectiveness of k-t GRAPPA for accelerating four-dimensional (4D) coronary MRA in comparison with GRAPPA and the feasibility of combining variable density undersampling with conventional k-t GRAPPA (k-t(2) GRAPPA) to alleviate the overhead of acquiring autocalibration signals. The right coronary artery of nine healthy volunteers was scanned at 1.5 Tesla."
"The 4D k-space datasets were fully acquired and subsequently undersampled to simulate partially parallel acquisitions, namely,...
