In this study a fat-suppressed and T2 contrast-prepared whole heart Zero Echo Time imaging (ZTE) sequence has been implemented and was evaluated in healthy adult volunteers, thus combining optimal contrast, volumetric coverage and short echo times into one single volumetric scan with very low acoustic noise. ZTE shows an image contrast comparable to standard sequences with the additional potential to depict short T2 signal from e.g. plaque or fibrosis. However, SNR problems related to maximum B1 and RF bandwidth limitations have to be addressed.
