What IS the difference between cat and pet scan?
The difference is in the type of radiation used to form the image. A Computed Axial Tomography (CAT) scan can use any type of radiation to create the image, the specific type is not specified in the name, but most often uses X-rays; but a Positron Emission Tomography (PET) scan specifically uses positrons as the radiation form. A third type, Magnetic Resonance Imaging (MRI) uses the miniscule magnetic fields of naturally occurring compounds within the human body to create its images.
Can a pet scan detect rheumatoid arthritis?
Yes.A PET Scan (or Positron Emission Tomography) Is a way of finding the most active areas in the body. the parts of the body that require the most energy use the most sugar, also referred to glucose). A PET scan uses a special material that imitates the sugar, and this is taken up by the cells in the area of activity. This material called a tracer has a small radioactive component attached to it. The images created as a result of PET scans are based on the detection of radiation from the emission of positrons (positively charged electrons) from the radioactive tracer. The subsequent images created are used to evaluate a variety of diseases, with the most common use being whole body imaging of cancer. Rheumatoid arthritis will be seen in a pet scan, However a pet scan will not tell you that it is RA that you are looking at. It will tell you that there is an area of high activity. At this stage the only way to be sure that you have RA is by recognising the symptoms and monitoring inflammation and any specific damage that may be done to various joints. through imaging such as Xray.
How long does a pet scan take?
A full body PET scan can take 30 to 45 minutes. A scan of a single lamp or a single organ can take as little as 10 minutes.
Does alcohol affect a PET Scan?
He'll yes.
Can you smoke before a PET scan?
No you cannot smoke before a PET scan because it will alter the results and it will be detecting in you system which may cause problems with the scanning process.

Can pet scan can be used on humans?
A PET scan is for humans.
How does a PET Scan use Radioisotope decay?
A PET scan uses radioisotope decay by detecting the pair of annihilation photons emitted during the decay process.
What brain imaging method requires the injection of a radioactive substance?
PET scan
What type of procedure is a PET scan?
cat scan
What is a ped scan?
Do you mean PET scan? That is a scan for cancer metastases, I believe.
What is a Diagnostic body scan that is referred to as a ped scan?
Are you talking about a PET scan?
What does mediastinal blood pool maximum SUV is 2.5 on a PET scan?
What does mediastinal blood pool maximum SUV is 2.5 on a PET scan?
What advantage does the MRI scan have over the Pet scan for the subject?
A PET scan shows what level / stage (if any) the cancer is at. An MRI scan doesn't do this, the reader, looks for abnormalities on the scan which shows up everything in the body.
Can you have a pet scan and bone scan on same day?
Yes, but bone scan has to be completed first.

Is attenuation correction thickness in a PET scan for length between slides or tumor thickness?
Attenuation correction in PET scans is actually aimed at accounting for the differences in the attenuation of the radiation signatures exhibited by different tissues because of the losses that materials impose on radiation passing through it. There are whole textbooks on this subject, and it is quite involved.
