Measurement of the standardized uptake value (SUV). The volume of interest (VOI) was placed over the accessory navicular bone (ANB). Transaxial CT images of ANB types (upper row) and SPECT/CT fusion images with their corresponding VOIs (bottom row) are displayed. Type 0 = contralateral navicular of unilateral ANB patient, Types I, II (II-0 and II-1), III = ANB types according to the Geist classification. CT = computed tomography, SPECT/CT = single-photon emission computed tomography/CT, VOI = volume of interest.[6,7]
