- See:
MRI of Spine:
- Discussion:
- MRI is sensitive for detecting infection & is specific in differentiating
infection from tumor;
-
infection:
-
T1 weighted images:
- decreased signal intensity in vertebral bodies & disk w/ inability to
discern a margin between disk & adjacent vertebral bodies;
-
T2 images
- increased signal intensity in verterbral bodies;
- increased signal intensity of intervertebral disk;
- absence of intranuclear cleft on T2 weighted image;
- Diff Dx:
-
metastatic tumor:
- there is absence of involvement of disk space;
