Descriptive Information
Brief Title  ICMJE Calcitonin Pre-treatment to Improve SPECT-CT Sensitivity
Official Title  ICMJE Improving the Sensitivity of Sestamibi SPECT-CT Parathyroid Scan With Calcitonin Pre-treatment for Primary Hyperparathyroidism
Brief Summary Patients with biochemically confirmed primary hyperparathyroidism and non-localizing SPECT-CT exam within the past year will be included. Subjects will be treated with calcitonin to lower calcium levels immediately prior to reimaging. The goal of this study is to determine whether lowering calcium will improve uptake/retention of sestamibi and improve sensitivity of SPECT-CT to localize parathyroid adenoma.
