You will lie on a special table and be moved into the machine, which looks like a large donut. It detects and records the radiation levels of the substance, which was introduced earlier. Images can be viewed on a computer monitor. Scanning takes about 30-45 minutes. You may be asked to change the position of the body, or perform specific tasks. For Example, during a heart PET, you may be asked to walk on a treadmill.

After PET

It is necessary to drink plenty of fluids, to radioactive substances out of the body.

How long will the Positron Emission Tomography?

At least, two hours.

Позитронно-эмиссионная томография – будет ли это больно?

In addition to the injection of injection, PET is a painless procedure. People, которые страдают клаустрофобией (fear of enclosed or confined spaces), могут испытывать некоторое беспокойство.

The pictures will show the activity of fabrics in different colors or shades of brightness. The radiologist will examine the images and send the results to your doctor. Getting a doctor report may take several days.
