摘要：

Magnetic resonance imaging has been used to characterize muscle fiber types, Here, T-1 and T-2 values were determined in pure slow-twitch and fast-twitch rabbit muscles and in rabbit muscles with mixed fiber types, The muscles with high proportions of oxidative slow-twitch fibers had higher T-2 values than the others, Echo time, orientation of muscle fibers in B-0, and moving spins had no effect on relaxation parameters, The results are discussed in terms of slow myosin isoform content and oxidative metabolism.
