SNR, contrast and relaxation times of the knee joint were measured at 7.0T using a whole body scanner. High resolution 3D-FLASH provides excellent contrast among various musculoskeletal tissues in vivo. This study demonstrated that there is ~35-45% increase in T1 when compared to 3T but no significant changes in T2 are observed. The T2 advantage can be exploited for improving spatial and temporal resolution especially for musculoskeletal system at 7T.
