This study analyzed the relationship between the cross-sectional area (CSA), effective lateral relaxation rate (R2* value), fat fraction (FF value) of lumbar paraspinal muscles of patients with chronic low back pain (CLBP group) and asymptomatic control group (Control group). The multifidus muscle and erector spinae muscle at the central level of the L4/L5 intervertebral disc were the target muscles.BOLD and IDEAL-IQ provided a new idea for imaging evaluation of lumbar paraspinal muscles. Our study concluded that BOLD and IDEAL-IQ are feasible to evaluate the changes of lumbar muscle morphology and function in patients with CLBP.
