Fig. 4From: Effect of diminished flow in rabbit lumbar arteries on intervertebral disc matrix changes using MRI T2-mapping and histologyRepresentative color-coded T2 maps in the sagittal plane of the rabbit lumbar spine. The region of interest (ROI) was determined at the borders of the annulus fibrosus (AF) and nucleus pulposus (NP) (a). At eight weeks after surgery, compared to the control disc (b), the signal intensity in the center of the nucleus pulposus changed in the cranial disc (c), bilateral disc (d) and caudal disc (e). T2-value (ms) of each disc was indicatedBack to article page
