| Zusammenfassung | In current clinical cardiac MR (CMR) integrated body RF coils are commonly used for 1H excitation, which deposit the RF energy/SAR in a large volume of the patient/subject.Progress in ultrahigh field MR (B0≥7T), where body RF coils are not provided, demonstrated that local transceiver (TX/RX) RF coil arrays are suitable for RF excitation of deep lying regions such as the heart.Recognizing this opportunity, this work demonstrates the feasibility of CMR at 3T with a local four-channel TX/RX RF coil array. This setup is benchmarked against the clinical standard of a body RF coil for excitation in conjunction with a four-channel RX-only RF coil.Our assessment includes electromagnetic field (EMF) simulations to detail SAR and B1+-homogeneity and -efficiency for the local and body RF coil configuration and their in vivo performance for high spatial resolution 2D SSFP-CINE imaging of the heart. |
