1. Type 1 pedicle marrow signal intensity changes associated with degenerative facet disease.
Type 1 pedicle marrow signal intensity changes associated with degenerative facet disease. A 60-year-old patient with back pain and degenerative facet changes. Parasagittal T1, T2, and STIR images are shown, left to right. On the T1 image, hypointensity is present within the pedicle and superior articular facet of L3 (long arrows). Hyperintensity is noted within this same region on T2- and STIR-weighted sequences (long arrows) as well as within the pedicle of L2. Note the subtle hyperintensity within the soft tissues adjacent to the facet joints at both levels on the STIR image (block arrows).
