Adding the fourth dimension to computed tomography neck in the evaluation of parathyroid adenoma

Parathyroid adenomas are the most common cause of primary hyperparathyroidism. Various imaging modalities such as ultrasound, nuclear medicine imaging studies, and multiphase computed tomography (also known as “four-dimensional” [4D] CT) are the most often used and highly approved imaging modalities for pre-operative diagnosis and localization of adenomas. Accurate pre-operative imaging is of prime importance to facilitate surgery, which is the definitive management, and 4D CT proves to be advantageous.
