Abstract
The purpose of this review is to evaluate the role of SPECT/CT in identifying facet joint arthropathy and the outcomes of interventions with SPECT/CT as an adjunct. A positive finding of facet arthropathy on SPECT/CT is associated with a higher likelihood of a unilateral procedure and a significantly more effective intervention compared with those performed on patients with facet arthropathy diagnosed only by clinical and/or radiologic examination. Surgical treatment of SPECT/CT-positive findings appears to have a good effect; however, due to limitations in the available studies, no strong conclusion can be drawn. SPECT/CT has a good correlation identifying pain generators in chronic neck and back pain. SPECT/CT-targeted facet interventions demonstrate a higher success rate, but SPECT/CT is not recommended as a first-line diagnostic tool prior to diagnostic facet interventions. More robust studies are needed to confirm the higher success of surgical treatment for SPECT/CT-positive facet arthropathy.
