From: Effect of percutaneous nucleoplasty with coblation on phospholipase A2 activity in the intervertebral disks of an animal model of intervertebral disk degeneration: a randomized controlled trial

Figure 2

Signal intensity of the disks in animal model group. (a) T2-weighted spin-echo images show four normal intervertebral disk signals in the control group (white arrows). (b) Two degenerative intervertebral disks in the coblation group with lower signal intensity than normal disks (1 month after stabbing; original magnification × 2). (c) T2-weighted spin-echo images show two “black disks” with disk intensity of grade 4 in the coblation control group at 8 weeks after stabbing (white arrows, original magnification × 1.5).
