Example of an xSPECT Bone reconstruction providing SPECT images with bone anatomy appearance. The xSPECT Bone® maximum intensity projections (MIP) combines scintigraphic data with morphological data from the computed tomography. In this example, the scintigraphy was performed in order to explore an acute low back pain. The exclusive use of the xSPECT Bone® MIP (a) makes it possible to visualize on one image an uptake related to a fracture of a vertebral body responsible for spinal angulation, to identify the vertebra concerned (L3), to visualize an uptake localized on the fifth right transverse process extended to the zygapophysial joint, and to visualize an uptake of the last right zygapophysial joint and an uptake asymmetry of the sacroiliac joints. Transaxial image analysis confirms the fracture of the L3 vertebral body (b) and specifies its extension toward the pedicles. It also confirms the uptake of the fifth right transverse process (c), of the last right zygapophysial joint (d) and the uptake asymmetry of the sacroiliac joints (e)
