1 Contrast enhancement of an annular tear at initial and follow-up imaging.A, Annular tear shows contrast enhancement. Contrast enhancement of an annular tear at initial and follow-up imaging.A, Annular tear shows contrast enhancement. Sagittal T1-weighted contrast-enhanced MR image (600/14 [TR/TE]) of the lumbar spine shows focal contrast enhancement at the posterior margin of the L5-S1 disk.B, Image of the same patient shown in A. Sagittal T1-weighted contrast-enhanced MR image (600/14) obtained 24 months later reveals persistent enhancement of the annular tear at the posterior margin of the L5-S1 disk. Fletcher M.
