Heterogeneous tracer uptake was noted at multiple spinal levels with marked increased focal tracer uptake in the right lateral aspect of L3 (Figure 1).
SPECT/CT images (axial, sagittal, coronal) localizing intense, focal tracer uptake to the right L3/L4 facet joint (continuous arrow). Note is made of mild tracer uptake in the right L5/S1 facet joint (dashed arrow).
