FIG 3. Comparison of patients with and a patient without Schmorl's nodes, the most common pathologic finding.
A, Schmorl's nodes at the lower thoracic and lumbar levels in a 38-year-old man. The 1H MRS shows a water peak (left) and a lipid peak (right). The LWR is 1.1, which yields a %FF of 52. This is relatively high for this age group (see fig 2).
B, Schmorl's nodes at the inferior endplates of L2 and L3 in a 60-year-old man. The 1H MRS shows the lipid peak (right) to be much higher than the water peak (left). The LWR measured 1.76, which yields a %FF of 64. This is relatively high for this age group (see fig 2).
C, Normal bone in a 17-year-old girl. The LWR measured 0.19, which yields a %FF of 16.
