Chulalongkorn Medical Journal
Background: Approximately 20.0% of hyperfunctioning parathyroid lesions do not exhibit typical enhancement characteristics on Four-dimensional computed tomography (4DCT). The two main mimics of hyperfunctioning parathyroid lesions are thyroid tissue and lymph nodes.
Objective: The study aimed to characterize enhancement patterns of hyperfunctioning parathyroid lesions on four-dimensional computed tomography (4DCT) and to differentiate hyperfunctioning parathyroid lesions from thyroid gland and lymph node.
Methods: This retrospective study included analysis of 47 hyperfunctioning parathyroid lesions either pathologically proven or uptake on Tc99m-sestamibi SPECT-CT. The attenuation of hyperfunctioning parathyroid lesions, thyroid glands, lymph nodes and muscles at non-contrast, arterial phase and delayed phase were …
