Fig. 3C. —Compartmental differences in glycosaminoglycan distribution
(T1Gd) index. Sagittal T1Gd image of 53-year-old man
obtained 10 years after medial meniscectomy shows extensive medial
degradation. Large region of distinctly lower T1Gd index values are
seen in femoral condyle, with sharp demarcation between that region and
surrounding cartilage. T1Gd index of degraded area (red)
is 35% lower (289 ± 63 msec) than index of surrounding tissue (440
± 74 msec).
