You’ll sit in the chair for about an hour or so though the radiotracer moves through your bloodstream and receives absorbed by your organs and tissues. Excessive action can ship the radiotracer to areas of One's body that the Health care company isn’t testing. You gained’t have the capacity to sense the radiotracer.
For those who’ve presently been diagnosed with most cancers, your service provider might advocate multiple PET scan all over your therapy to:
The client is quickly moved head to start with into your CT gantry, as well as the x-ray tomogram is acquired.

Even so, if the result of a 3-month PET-CT scan is unfavorable for most cancers, then the NCCN consensus is that there's probable no price additional by obtaining extra scans at lengthier intervals.
As unstable eighteen-F decays, it releases positrons. In just about 2 mm of vacation from their origination web-site in tissue, positrons collide with electrons and release gamma Electrical power (photons). The photons strike scintillator crystals housed in a device that encircles the affected person. Crystals Utilized in present day imaging devices change by company, Each and every with its have photon detection generate and resolution; a common crystal form used for PET is lutetium oxyorthosilicate. The crystals transmit the photoelectric Vitality into circuits that convert the electric energy into Personal computer facts.
