Single Photon Emission Computerized Tomography
Also known as: SPECT, SPECT scan.
What is a single photon emission computerized tomography?
Single photon emission computerized tomography (SPECT) is a nuclear imaging test that shows brain/other organ function by measuring blood flow in the brain/organ.
What happens during the procedure?
A safe, short acting radioactive substance is injected into a vein in your child’s arm and a CT (computed tomography) scan is performed shortly thereafter.
Is any special preparation needed?
The patient may need to avoid food, drink or medication for a period of time before the test. All jewelry or anything metal should not be worn during the test.
What are the risk factors?
While radiation is a small risk, the material injected is quickly removed from the body and the benefits of the study far outway any small risk present. Inserting a small needle into a vein can (but not usually) be associated with pain, bleeding, swelling, infection and other problems.
