Intraoperative Scintigraphy Using a Large Field-of-View Portable Gamma Camera for Primary Hyperparathyroidism: Initial Experience

Figure 3

Preoperative MIBI planar image of a patient with positive diagnostic MIBI imaging at 15 minutes after injection (left image) and 120 minutes (right image) after administration of the radiolabeled agent showing activity in the left superior parathyroid (white arrow). (a) Intraoperative, preincision LFOVGC image identifying the single focus of activity (yellow circle) and normal uptake in the salivary glands (yellow arrow). (b) Digital photo of the resected tissue (left image) and the resultant LFOVGC image of the same excised tissue confirming MIBI-avid specimen (right image). (d) Intraoperative, postexcision, and LFOVGC image of the patient’s neck showing absence of targeted residual activity (yellow circle) and verification of a complete resection.
