Bone scintigraphy, the most common form of nuclear medicine, detects biochemical changes through images that are produced by scanning and mapping the presence of radiographic compounds (usually technetium Tc 99m phosphate or gallium 67 citrate). The degree of spondylolisthesis is categorized as grade 1 through grade 4, based on that position (Figure 5). These compounds are incorporated into hydroxyapatite crystals that are deposited in an osteoid matrix during new bone formation.
