32-element receive coil arrays offer significant SNR gains over birdcage coils, which can be traded for faster scans of improved spatial resolution. Here we demonstrate in vivo 2D CTPRESS on a 3T Siemens Tim Trio with spiral encoding at a spatial resolution of 0.85cc with minimum scan time of 5:16min. Four averages were taken for improved SNR, resulting in a total scan time of 20:32min.
