Full 3D high-resolution human placenta BOLD imaging at 3T was performed with a free-breathing prospectively navigated sequence using 2D spatially selective excitation. Advantages of this sequence over conventional multi-slice breath hold BOLD include increased SNR, no breath hold recovery periods leading to better time efficiency, and elimination of artifacts from respiratory and fetal motion. T2* maps clearly show the cotyledon architecture of the human placenta.
