Bilateral neck exploration is the standard procedure in primary hyperparathyroidism. Using a bilateral approach, preoperative localization studies are not mandatory. A localized single gland disease is the basis for a minimally invasive procedure. Therefore preoperative localization techniques play an important role in planning (minimally invasive) first time exploration for primary hyperparathyroidism. The combination of (99 m)Tc-SestaMIBI scintigraphy with ultrasound allows correct localization of the parathyroid adenoma in 86 % of all single gland diseases. Multiple gland disease could be predicted in isolated cases only. Computerized tomography and magnetic resonance imaging could not improve the results. Surgery for persistent or recurrent hyperparathyroidism should only be performed after positive localization studies.

UI MeSH Term Description Entries
D006961 Hyperparathyroidism A condition of abnormally elevated output of PARATHYROID HORMONE (or PTH) triggering responses that increase blood CALCIUM. It is characterized by HYPERCALCEMIA and BONE RESORPTION, eventually leading to bone diseases. PRIMARY HYPERPARATHYROIDISM is caused by parathyroid HYPERPLASIA or PARATHYROID NEOPLASMS. SECONDARY HYPERPARATHYROIDISM is increased PTH secretion in response to HYPOCALCEMIA, usually caused by chronic KIDNEY DISEASES.
D010280 Parathyroid Glands Two pairs of small oval-shaped glands located in the front and the base of the NECK and adjacent to the two lobes of THYROID GLAND. They secrete PARATHYROID HORMONE that regulates the balance of CALCIUM; PHOSPHORUS; and MAGNESIUM in the body. Gland, Parathyroid,Glands, Parathyroid,Parathyroid Gland
D003952 Diagnostic Imaging Any visual display of structural or functional patterns of organs or tissues for diagnostic evaluation. It includes measuring physiologic and metabolic responses to physical and chemical stimuli, as well as ultramicroscopy. Imaging, Diagnostic,Imaging, Medical,Medical Imaging
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012680 Sensitivity and Specificity Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed) Specificity,Sensitivity,Specificity and Sensitivity
D014463 Ultrasonography The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1.6 to 10 megahertz.

D015899 Tomography, Emission-Computed, Single-Photon A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.
