Tc-99m sestamibi for detection of parathyroid adenoma. Comparison of single and dual tracer imaging.

Single and dual radionuclide techniques have been described in localization of parathyroid adenomas. Although single radionuclide imaging with Tc-99m sestamibi has many advantages, it can fail to demonstrate a parathyroid adenoma, which, in the case presented, is well demonstrated with dual radionuclide imaging. The authors recommend dual tracer imaging when searching for parathyroid adenoma.
