title: Dynamic or early imaging in dual-tracer parathyroid scintigraphy.
abstract: The dual tracer radionuclide method using Tl-201 and Tc-99m subtraction imaging has proven to be effective for evaluation of parathyroid lesions. Ninety-two percent sensitivity for detection of parathyroid adenomas has been reported. The importance of dynamic or early imaging, however, has not been emphasized. A case of surgically proven parathyroid adenoma was detected using dynamic scanning after Tl-201 injection and was less apparent on delayed image due to rapid washout.
