Presentation transcript:

Type 1 pedicle marrow signal intensity changes associated with new and old pedicle fractures in a 64-year-old woman. Type 1 pedicle marrow signal intensity changes associated with new and old pedicle fractures in a 64-year-old woman. A, Right parasagittal T1-, T2-, and STIR-weighted images that demonstrate a discrete fracture line through the pedicles of L4 bilaterally without pedicle marrow signal intensity changes (long arrow) and a less obvious fracture line on T1 images through the L5 pedicle with concomitant type 1 pedicle marrow changes (short arrows). Signal intensity changes at L5 and clinical symptoms had resolved at 8 months of follow-up. B, Right and left parasagittal multiplanar reformatted CT images through the lumbar spine and axial images through the pedicles of L5. Note the lucent appearance of the subacute fracture site through the pedicles on the parasagittal multiplanar reformatted images and adjacent axial CTs and the less well-defined fracture and adjacent marrow signal intensity alteration through the pedicles on the axial MR images (arrows).The signal intensity change is more obvious on the axial MR image on the right. Note the sclerotic appearance of an older fracture site through the L4 pedicle on the CT images. B. Borg et al. AJNR Am J Neuroradiol 2011;32:1624-1631 ©2011 by American Society of Neuroradiology
