These scans aren’t as commonly performed for the detection of cancer, though some forms of the gallium scan are combined with newer tests such as the PET scan. Gallium scans are typically performed one to three days after the tracer is administered, so it’s a multiday process. A computer changes the results into 3-D pictures. A PET scan is used to inspect blood flow, oxygen intake, or the metabolism of organs and tissues. I think knowing that I was going to be in there for about 25 minutes and not knowing how the scan would work (how much I'd be in and out of the tube), etc, I think just freaked me out. However, you cannot undergo a PET–MRI with nonapproved medical devices or metal implants. protons) using alternating voltage in a magnetic field. PET scans are an outpatient procedure, which means you go home the same day. During the scan, your child will lay flat on a table that moves in and out of a doughnut-shaped MRI machine. The tracer will collect in areas of higher chemical activity, which is helpful because certain tissues of the body, and certain diseases, have a higher level of chemical activity. A PET scan can show how an organ works, but without a CT or MRI image, it can be difficult to pinpoint the exact location of activity within the body. A positron emission tomography, also known as a PET scan, uses radiation to show activity within the body on a cellular level. The tracer is essentiallyglucose with the radioactive component attached. Is there a link between ocean pollution and damage to human health? How does the PET scan compare to other tests?
