What is the scanning of isotopes?
isotope scanning is a medical procedure that creates pictures of the inside of the body. A radioactive substance is used during the procedure. This substance migrates for scanning into the body area. A special camera and computer are used to create images. The isotope or used radioactive substance used and the procedure varies slightly depending on which part of the target is focused on.
The first step in scanning isotopes is the transmission of isotope to the body. This is done in a number of ways that include injection into a vein, inhalation or drinking of fluid that contains isotope. The type of isotope used and the way it enters the body depends on the targeted part of the body.
images produced by scanning isotopes are made of gamma rays. Gamma rays are distributed by a radioactive substance inside the patient. These rays are picked up with a special camera and then sent to the computer. The computer then creates a picture using various Intenses of Gamma rays provided by the camera.
Isotopes scanning are effective in the diagnosis of conditions, as radioactive agents are attracted to the most active tissues. This allows doctors to see a clear picture of the tissue that is active and healthy versus inactive tissue. The area of activity is called hot spots, while areas with low cellular activity are referred to as cold sites. The hot spots appear in the picture as a red and cold spot are blue.
Isotope scanning is used to create images of bones, lungs, thyroid and kidneys. The procedure approaches the activities in each of these bodies. For example, if scanning shows clusters of thyroid activity, then there is evidence of some gland hyperactivity.
There is no need for small preparation for this procedure. A physician of each individual or hospital will provide detailed instructions. Once the isotope is removed, then it takes time to achieve the intended part of the body. When it reaches the organ, pictures are taken. Quantity acquiredIt will vary depending on the individual's state. It may take several hours to scan isotopes.
When scanning isotopes, a low risk is involved. Women who are pregnant or nursing should not have a procedure due to the risks of exposure to the fetus or the child radiation. In addition to pregnant or nursing women, there is no need to worry because the amount of radiation is not significant enough to cause damage. The radioactive substance is naturally excluded from the body, usually within a few days.
