135 Review of the role of bone-SPECT/CT in tarsal coalitions Characteristic findings of imaging techniques in relation to the type of TC, based on a combination of literature and our experience, is shown in Table 1 and 2. Figure 11. a) Thirty-eight-year-old male patient presented with midfoot pain and plain radiographs were suggestive of TCC in the left foot (images not shown). Bone-SPECT/CT with intraarticular contrast medium shows non-osseous TCC of the posterior facet with increased bone turnover in the TCC; blue arrowheads pinpointing the intraarticular contrast medium, depicting a non-osseous TCC of the posterior facet with increased bone turnover in the TCC, in especially the talus (green circle). (b) Same patient as (a). Semiquantitative measurement of increased bone turnover in the non-osseous TCC on preoperative bone-SPECT/CT, with SUVmax of 12.8. (c) Same patient as (a and b). 3D reconstructions withmaximal intensity projections (MIP) may be helpful to inform the clinician. CT, computed tomography; TCC, talocalcaneal coalition. 5
