Figure 3: MRI T2-weighted image of a 56-year-old female. ((a) and (c)) Sagittal view. ((b) and (d)) Axial view. The significant increase in CDS was seen in L4-5 level (preoperative 0.44 to postoperative 0.92) at 24-month followup. Meanwhile, the signal intensity of T12-L1 demonstrated to be similar brightness. Arrow, reduced bulging disc after stabilization; arrowhead, significant increase in CDS.
