R1rho imaging can provide novel information on dynamic processes within tissues, allowing for a more comprehensive analysis of the parameters of chemical exchange and/or intrinsic microstructure. We measured the dispersion of R1rho with different locking fields in the major lumbar muscles of psoas, paraspinal muscles (multifidus and erector spinae), and quadratus lumborum. The results showed that R1rho dispersion is significant and measurable at 3T which may provide a new way to characterize muscles involved in low back pain.
