When high field strengths and small transmit-receive coils are used, SNR is no longer the sole limit to high-resolution imaging. Chemical shift and motion artifacts become major concerns. To address these concerns, a Cartesian gradient echo pulse sequence was designed with interleaved echoes for fat/water separation and interleaved navigators for motion correction. In vivo skin images with 100 μm isotropic resolution (1 nL) are presented. Fat/water separation allows the clear delineation of the different skin layers while motion correction effectively removes blurring.
