We studied ten healthy volunteers with both CENTRA-PLUS and conventional centric acquisition strategies matched for all other acquisition parameters. Scans were performed on a 1.5T Philips Achieva with a 5ch array (TR = 4.4 ms; TE = 1.9 ms; FA = 90; 300 × 300 × 120 mm3 acquired at 1.3-1.5 mm3 isotropic resolution, interpolated to 0.65 × 0.65 × 1.3 mm, sensitive encoding parallel imaging (r=2)). A fixed 5 mm gating window with no slice tracking was used. 5-point qualitative scores of coronary artery visualization (1= not visible, 5= excellent) and quantitative parameters including Signal-to-Noise-ratio (SNR) and Contrast-to-Noise-ratio (CNR) were evaluated using a fast noise scan for SENSE-accelerated analysis. Statistical analysis of SNR, CNR, and scan time was performed using Student's t-test and qualitative scores were assessed using Wilcoxon's Signed-Rank test.
CENTRA-PLUS is a promising acquisition scheme for coronary CMR resulting in improved image quality and SNR.
