(a) T2-weighted image of MRI before treatment in 2022-03-07 observation group; (b) T2-weighted image of MRI in 2022 after 2 months of treatment; the height and thickness of L4-L5 disc increased slightly compared with before treatment, and the degree of “bulging” of the diseased disc in (b) was reduced compared with (a); (c) T2-weighted image performance of L4-L5 disc level before treatment in 2022-03-07 observation group; (d) T2-weighted image performance of L4-L5 disc level 2 months after treatment in 2022-06-05 observation group, indicating that the MRI T2WI signal of the same disc was increased compared with preoperative, indicating the enhanced hydration of disc after treatment and no obvious fat infiltration.
