It fuses the images of a sestamibi scan with a CT scan done at the same time. 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. 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. Planar and SPECT parathyroid scintigraphy is performed 15–30 minutes and 2–4 hours after intravenous administration of 20–25 mCi (740–925 MBq) of Tc-99m sestamibi (, Fig 1) (, 10). The field of view encompasses the neck and thorax.

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.

[5–7] Parallel-hole imaging is the standard method for parathyroid imaging to evaluate the neck and mediastinum, but pin-hole imaging can provide better resolution. S Interpretation of Tc-99m sestamibi parathyroid SPECT-CT scans made easy for better surgical outcomes in patients with primary hyperparathyroidism Isis W Gayed,1 Ron J Karni,2 David Q Wan,1 Jeena M Varghese,3 Kelly L Wirfel,3 Kyoung S Won,4 Usha A Joseph1 1Nuclear Medicine Section, Department of Diagnostic and Interventional Imaging, 2Department of Otorhinolaryngology, Head and Neck Surgery 2018-05-01 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.

SPECT/CT allows three-dimensional (lateral, supero-inferior, and anteroposterior) localization of the parathyroid glands. Lateral localization may be described as right, left, or midline (, Figs 5,,, , 6,,). All protocols had perfect sensitivity for detection of parathyroid adenoma whereas SPECT was the most sensitive method for detection of hyperplastic parathyroid glands.

Objective: To evaluate 4-dimensional (4D) computed tomography (CT) for the localization of parathyroid adenomas previously considered nonlocalizing on ultrasound and single-photon emission CT with CT scanning (SPECT-CT). To measure radiation exposure associated with 4D … SPECT/CT: • Inject patient with Tc-99m Sestamibi • Early: 15 minutes post injection o Use predefined parathyroid protocol o 10-min Anterior static o SPECT with CT. • Image from top of heart (include a few slices of the heart) to the salivary glands • CT at full field of view • Delay: 2 hours post injection Parathyroid four-dimensional (4D) CT refers to multiphase computed tomography of the neck used to localize abnormal parathyroid glands (i.e., involved with adenoma, hyperplasia, or, rarely, carcinoma).The "4D" indicates that imaging is performed in multiple phases of contrast, with time being the fourth dimension in addition to the multiplanar format of CT; the number of phases is not 2019-10-05 Localization of Hyperfunctioning Parathyroid Glands.

It fuses the images of a sestamibi scan with a CT scan done at the same time. Parathyroid glands are small endocrine glands in the neck that produce parathyroid hormone. There are four parathyroid glands, which are usually located behind the thyroid gland and, in rare cases, within the thyroid gland or in the chest. Parathyroid glands control the amount of calcium in the blood and within the bones. Nuclear scintigraphy for parathyroid adenoma localization is usually performed with a single radiotracer (Tc-99m sestamibi). Immediate and 2-hour delayed planar images are obtained, in addition to an immediate or a delayed single-photon emission computed tomography (SPECT) or SPECT/CT acquisition.
