Multichannel transmit and receive coil arrays give promising results to overcome the challenges towards clinical cardiac imaging at ultrahigh field strengths. The comparison of 4-, 8- and 16-channel cardiac coils shows a higher SNR, CNR as well as image homogeneity while moving towards a higher number of TX/RX elements. Clinically relevant short axis and four chamber view cardiac 2D CINE FLASH, tag band prepared 2D CINE FLASH and 2D CINE SSFP images were acquired and compared.
