Fig. 1From: Quantifying cervical spondylosis: reliability testing of a coherent CT-based scoring systemDisc degeneration exhibited by one of the study patients. Height loss of the C5-C6 disc, measuring 2 mm in a mid-sagittal slice. The height of a non-degenerated disc (C2-C3) was measured 4.2 mm, resulting in a relative height loss > 50%- ≤ 75% (3 points)Back to article page
