Computed tomography radioisotope

Does CT use radioactive tracer?
Before your PET-CT scan, you will get an injection of a small amount of a radioactive sugar called fluorodeoxyglucose-18.
This substance is sometimes called FGD-18, radioactive glucose, or a tracer..
What is the radioactive material in a CT scan?
As in many areas of medicine, there are risks associated with CT scans, which use ionizing radiation to create images of the body.
Risks from exposure to ionizing radiation include: A small increase in the likelihood that a person exposed to radiation will develop cancer later in life..
What radioisotopes are used in computed tomography?
The radioisotopes typically used in SPECT to label tracers are iodine-123, technetium-99m, xenon-133, thallium-201, and fluorine-18.
These radioactive forms of natural elements will pass through your body and be detected by the scanner.
Various drugs and other chemicals can be labeled with these isotopes..
Where is radioisotopes located?
Radioactive isotopes of radium, thorium, and uranium, for example, are found naturally in rocks and soil.
Uranium and thorium also occur in trace amounts in water.
Radon, generated by the radioactive decay of radium, is present in air..
Why is radioactive imaging important?
Nuclear medicine uses radioactive material inside the body to see how organs or tissue are functioning (for diagnosis) or to target and destroy damaged or diseased organs or tissue (for treatment).
Images of the body show where and how the tracer is absorbed..
Why radioactive isotopes are used in CT scans?
Radioisotopes are an essential part of medical diagnostic procedures.
In combination with imaging devices which register the gamma rays emitted from within, they can be used for imaging to study the dynamic processes taking place in various parts of the body..
A radionuclide scan is an imaging technique that uses a small dose of a radioactive chemical (isotope) called a tracer that can detect cancer, trauma, infection or other disorders.
In a radionuclide scan, the tracer either is injected into a vein or swallowed.
By measuring the behavior of the radionuclide in the body during a nuclear scan, the healthcare provider can assess and diagnose various conditions, such as tumors, infections, hematomas, organ enlargement, or cysts.
A nuclear scan may also be used to assess organ function and blood circulation.
Types of radionuclide scans include PET scans, gallium scans and bone scans.
A radionuclide scan is painless, except for a mild skin prick if the tracer is injected.
Once the tracer is given, it takes several hours for the isotope to travel to the target organ.

Emission computed tomography (i.e., PET, SPECT) is the term for functional imaging methods that use injected radioisotopes and combine the principles of the tracer kinetic method and tomographic image reconstruction.

Single photon emission computerized tomography (SPECT) is the current major scanning technology to diagnose and monitor a wide range of medical conditions.

The SPECT-CT provides 10 percent better quantification accuracy than planar imaging, allowing its use for individualized radionuclide treatment planning. Such
