4D Parathyroid CT Using Photon Counting Detector-CT
4D parathyroid CT is a multiphase protocol used in the setting of hyperparathyroidism to detect parathyroid adenomas, largely identified by their attenuation patterns relative to the thyroid and enlarged non-lymphoid soft tissue in the central compartment. This technique has previously been described utilizing traditional energy integrating detector-CT. We present our protocol using photon counting detector-CT as a means of using increased spatial and contrast resolution to help identify parathyroid adenomas.ABBREVIATIONS: PCD-CT= Photon Counting Detector-CT, EID-CT = Energy Integrating Detector-CT.
