Bone metastases in pheochromocytoma. Optimal timing of I-123 MIBG scintigraphy.
The optimal timing of I-123 MIBG scintigraphy in the evaluation of pheochromocytoma is unknown. Although some centers perform early imaging, many delay imaging until 24 hours after injection. The authors describe the case of a bony metastasis in the left femur that was detected 5 hours after injection, but which was not visualized at 24 hours.
