SPECT Imaging of Epilepsy: An Overview and Comparison with F-18 FDG PET

Figure 1

Transverse tomographic images from a normal 41-year-old female subject after injection of 20 mCi Tc-99m ECD. The transverse images are arranged parallel to and sequentially above the canthomeatal line, with the cerebellum at the top left and the vertex of the brain at the bottom right. The scan thickness is 4 mm. The scan resolution is approximately 7 mm full width at half maximum.
