SPECT Scanning of Parathyroid Tumors

SPECT (Single Photon Emission Computerized Tomography) scanning is a 3-D method of Parathyroid Sestamibi Scan. With this method 3-dimensional images of the parathyroid can be taken after Technetium-99m Sestamibi is injected. This method is 2-3 percent more accurate than a standard parathyroid scan. During the scan many images are taken around the patient's head covering different angles. We typically reserve this technique if a Sestamibi scan was performed at another hospital, but was found to be negative.
