A 48-year-old male with disc herniation at L4-L5 (red arrow) (a) The CSA of the paraspinal muscles was measured by drawing the outline of the muscle fascial boundary using the range of interest (ROI) at the L4-L5 intervertebral disc level on axial T2-weighted MRI. (i) ROI of multifidus muscle; (ii) ROI of erector spinae muscle; (iii) ROI of psoas. (b) Measurement of the fatty degeneration of the multifidus muscle was performed using a threshold method. The procedure of percutaneous endoscopic lumbar discectomy (PELD) for treating disc herniation at the left side of the L4-L5 intervertebral disc level on axial T2-weighted MRI (blue line)
