Parathyroid four-dimensional (4D) CT has emerged as a promising method for preoperative localization. Purpose To evaluate the diagnostic performance of parathyroid 4D CT and technetium 99m-sestamibi (hereafter, referred to as sestamibi) SPECT/CT in preoperative localization in patients with primary hyperparathyroidism.

Fusion SPECT-CT can further aid anatomic localization. 18F-fluorocholine PET/CT may also have a role 18. As the SPECT and SPECT-CT codes were being re-vamped, there are a couple that are not impacted by the change: myocardial perfusion and parathyroid imaging have retained their site-specific SPECT codes. Continue to report these as usual. parathyroid glands in patients with documented hyperparathyroidism.

2011-07-27 · Primary hyperparathyroidism is caused by a single parathyroid adenoma in up to 90% of clinical cases. Selective surgical excision of the hyperfunctioning parathyroid gland is the treatment of choice for this condition, and parathyroid scintigraphy is one of the primary and standard methods used for preoperative localization. SPECT/CT is advantageous over planar imaging because SPECT/CT

Inferior Parathyroid Embryology The IPG arise from the dorsal wing of the 3rd pharyngeal pouch, that differentiates at gestational weeks 5-6, with the ventral wing becoming the thymus. The thymus then migrates caudally and medially, pulling the IPG with it; therefore, IPG IIIs are further inferior than are SPG IVs. Parathyroid four-dimensional (4D) CT has emerged as a promising method for preoperative localization.

Thus, it is not surprising that there is growing literature describing the many advantages that contemporary SPECT/CT technology brings to radionuclide investigation of endocrine disorders, showing potential advantages for the pre-operative locating of the parathyroid adenoma using a minimally invasive surgical approach, especially in the presence of ectopic glands and in multiglandular disease.

Parathyroid Imaging and Localization Using SPECT/CT: Initial Results Ana Vaz1 and Marc Griffiths2 1Torbay Hospital, South Devon Health Care Foundation Trust, Torquay, United Kingdom; and 2University of the West of England, Purpose: Single photon emission computed tomography/computed tomography (SPECT/CT) now makes it possible to use combined morphologic CT and functional scintigraphy information. It has proved useful for localization of abnormal parathyroid glands, especially in the case of an ectopic gland. Dual-phase parathyroid scan with 99m Tc-sestamibi is a standardized imaging method for diagnosing parathyroid adenoma and hyperplasia. Conventional planar images using a gamma camera are performed routinely in early and delayed time points, followed by a single SPECT-CT.
