Overview
Bone scintigraphy may be helpful in selected ankylosing spondylitis patients with normal or equivocal findings on sacroiliac joint radiographs. The ratio of SI joint to sacral uptake of 1.3:1 or higher of the radionuclides is considered abnormal.
Other imaging findings
Bone scintigraphy
- May be helpful in selected patients with normal or equivocal findings on sacroiliac joint radiographs
- Qualitative assessment of accumulation of radionuclides in the SI joints may be difficult due to normal uptake in this location. Thus quantitative analysis may be more useful.
- Ratios of SI joint to sacral uptake of 1.3:1 or higher is abnormal
