1. Review the current imaging findings in investigations of primary hyperparathyroidism caused by a parathyroid adenoma (ultrasound, MIBI and SPECT MIBI) 2. Review the enhancement and attenuation characteristics of parathyroid adenomas using IV enhanced dual energy CT Neck. 3. Review the physics behind Dual Energy CT and it's applications in parathyroid imaging. 4. Illustrate the attenuation characteristics of pathology proven parathyroid adenoma at multiple different KeVs, and compare these differences with thyroid tissue, thyroid nodules and lymph nodes.

Background on the radiological work-up for patients being investigated for primary hyperparathyroidism including pictorial examples of ultrasound findings and more advanced nuclear medicine imaging including MIBI studies and combined MIBI SPECT images CT contrast enhanced neck in parathyroid localisation - enhancement and attenuation patterns of adenomas and how they differ from thyroid tissue, thyroid nodules and lymph node Background on Dual Energy CT, it's physics, it's utility and application in parathyroid imaging   The utility of Dual Energy CT neck in localizing parathyroid adenomas and where it may play a future role in localizing adenomas at acceptable or even reduced radiation dose.
