A new 64-channel cardiac phased array prototype coil was
compared to a commercial 30-channel coil setup (Body
18/Spine 32 Tim coils) to assess imaging performance in
healthy volunteers. Accelerated cine cardiac MRI
(tGRAPPA, acceleration factors R = 3, 5, 7, and 8) was
performed in short-axis and four-chamber views. MR
images were scored by an independent radiologist for
image quality in terms of diagnostic value (1 =
Excellent, 2 = Good, 3 = Satisfactory, 4 = Fair, 5 =
Fail). The 64-channel coil outperformed the commercial
setup at R = 5 and R = 7, resulting in lower score
values.
