radionuclide scanning

radionuclide scanning

A method of body imaging using elements that emit radiation (radionuclides) and which are incorporated into compounds that concentrate in certain parts of the body or in diseased areas. The location of the radionuclide is shown on an image produced by a device called a GAMMA CAMERA. The method can, for instance, reveal cancer, both primary growths and unexpected METASTASES, especially in the brain.

Radionuclide scanning

Diagnostic test in which a radioactive dye is injected into the bloodstream and photographed to display internal vessels, organs and tissues.

However, the days of invasive diagnostic procedures such as pneumoencephalography, myodil ventriculography, echoencephalography, radionuclide scanning, and contrast angiography are now over and with the introduction of computed tomography (CT) and magnetic resonance imaging (MRI) scanning, imaging of brain SOLs has acquired new dimension whereby excellent anatomical detail in axial, sagittal, and coronal planes as well as tumor tissue characterization has become possible.
For the masses in the salivary glands area, sialography, US, and radionuclide scanning are all of value [7].
(2) Technetium radionuclide scanning done in patients presenting with ulceration, bleeding or anemia may show gastric mucosa in the cyst.
Radionuclide scanning This technique produces images using radiation emitted from a substance within the body.
If the diagnosis is equivocal radionuclide scanning is helpful in detecting the blood flow.
(3) Low TSH suggests autonomous nodules and the ATA recommends radionuclide scanning with FNA of hypofunctioning nodules with suspicious US features.
Radio-pharmaceuticals seek out actively metabolizing bone such as a fracture site and radionuclide scanning can therefore be of greatest use in cases of questionable findings in hip or spine fractures and occult trauma.18 In practice this remains the most under-utilized radiologic modality in medicolegal fractures despite the potential.10,19 Others such as ultrasound and interventional radiology have not been employed for the purpose under consideration as yet.
Standard diagnostic methods for testicular torsion (i.e., Doppler US and radionuclide scanning) remain unresolved and insufficient in some cases, according to the literature.[sup.4] In such indeterminate situations, the cases are directed immediately to surgery.
Furthermore, it includes instructions for cytologic reporting, radioiodine ([.sup.131]I) treatment of multinodular goiter, recommendations for percutaneous ethanol ablation of cystic nodules, and radionuclide scanning.

The task force encourages endocrinologists to seek proper training for ultrasound use, obtain ultrasound equipment for their offices, and apply the procedure generously in their practices.
Of the 307 patients, 121 (39%) had undergone echocardiography either during their index hospital stay (88) or previously (33); no patient had had radionuclide scanning or left ventriculography performed.
