Thyroid Iodine (Child)

  • Preparation for scan is required. Please contact our practice. 

Iodinated MIBG (I-123) is concentrated in the adrenal medulla and while the quantity taken up is insufficient to image normal adrenals, in patients with phaeochromocytoma, neuroblastoma, and adrenal medullary hyperplasia, uptake is much higher. Imaging with I-123 MIBG may also be used to assess uptake prior to therapy with much larger quantities. The patient's thyroid must be blocked with potassium iodide prior to administration of the radiopharmaceutical. Imaging is generally commenced 24 hours after administration and may be repeated at 48 and 72 hours.
