Parathyroid CT Scan
A high resolution parathyroid CT(Computerized Tomography ) scan is sometimes used to help localize a parathyroid tumor when a parathyroid scan and parathyroid ultrasound were unsuccessful at localizing the tumor. This technique is sensitive but not specific. A CT scan takes detailed pictures of the body through x-rays.
Although parathyroid CT is not always a first line modality; if a Sestamibi scan of the parathyroids and ultrasound are negative then a CT of the parathyroids is performed to help identify a parathyroid adenoma in an aberrant location.
