Definition Of Isotope Scan

A radionuclide is used which collects in areas where there is a lot of bone activity where bone cells are breaking down or repairing parts of the bone.

Definition of isotope scan. A radionuclide sometimes called a radioisotope or isotope is a chemical which emits a type of radioactivity called gamma rays. Thyroid scans can help your doctor determine if your thyroid is working properly. Bone scans use radionuclides to detect areas of the bone which are growing or being repaired. This type of scan also involves the use of radiation.

The isotope which is attached to a component of bone tissue which is taken up by active bony tissue is then incorporated into the bone. A diagnostic method of examining the interior of the body using a scanner and radioactive material injected into the veins and organs. Isotope definition is any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties. These areas of activity are seen as hot spots on the scan picture.

During the procedure a radioactive substance is ingested. A tiny amount of radionuclide is put into the body usually by an injection into a vein. A bone scan is a common type. There are 275 isotopes of the 81 stable elements in addition to over 800 radioactive isotopes and every element has known isotopic forms.

Used extensively although not entirely reliably for localization of parathyroid tumors by subtraction of the images made with thallium 201 and technetium 99m. This substance migrates to the area of the body being scanned. An isotope scan is a medical procedure that produces pictures of the inside of the body. Dual isotope scan scintiscan made with two isotopes measuring their specific energy levels independently.

In this case a radioactive isotope is injected into your blood. These chemicals localise to specific organs and tissues depending on the type of substance used and then emit small beams of radiation called gamma rays that can. A special camera and computer is then used to create pictures. How does a bone scan work.

A radionuclide scan also known as a radioisotope scan is an imaging technique used to visualise parts of the body by injecting a small dose of a radioactive chemical into the body. You may also have a radioactive iodine uptake raiu test with the scan to measure your thyroid s reaction.
