Figure 2.

18F-fluorocholine positron emission tomography/computed tomography (a) Maximum intensity image (MIP), showed focal fluorocholine uptake in lower neck in the region of suprasternal notch on the right side (thick arrow), (b and c) transaxial fused positron emission tomography/computed tomography and computed tomography images showed soft tissue density nodule in the region of right inferior parathyroid gland with focal increased fluorodeoxyglucose uptake. Four-dimensional computed tomography images (d-g) showing right inferior parathyroid adenoma (arrow) with intense enhancement on arterial phase and washout on venous phase
