Dual energy 4D-CT of parathyroid adenomas not clearly localized by sestamibi scintigraphy and ultrasonography - a retrospective study.

Purpose: At present, the gold standard for diagnosing PAs includes ultrasonography of the neck and sestamibi scans of the parathyroid. The objective of this study was to evaluate scans performed in 4D-DECT (4D-dual-energy mode) at three different time points, in order to analyze spectral information from PAs, lymph nodes (LNs), and thyroid gland (Thy).

Method: Fifteen patients (mean age: 57 ± 18.
