Following the exam you can keep on using your working day as regular, unless your overall health Expert informs you if not. You will need to consume plenty of fluids to aid flush the tracer from the physique.

Two- and 3-dimensional picture reconstruction may be rendered for a perform of a standard program and Handle procedure.[1]
Positron emission tomography (PET) scans detect early indications of most cancers, heart disease and brain conditions. It will involve an injection of a safe radioactive tracer that assists detect diseased cells.
Regions of greater intensity are termed “warm spots.” These may well present substantial concentrations of the radiotracer and exactly where There's a significant level of chemical or metabolic activity. Much less rigorous spots, or “cold spots,” reveal a more compact concentration of radiotracer and fewer action.
You’ll lie on an Test table that slides out and in of the PET/CT scanner. This scanner is formed similar to a doughnut. The doughnut or tunnel opening is about 30 inches in diameter.

If following 12 months the PET-CT is ambiguous, then the NCCN recommends getting a subsequent PET-CT or subsequent CT if no biopsy is performed.[four] Shenzhen CT Pet Supplies Co., Ltd.
A PET scanner is a sizable device having a spherical, donut-formed hole in the center. It looks like a CT or MRI unit. Multiple rings of detectors Within the equipment file the Electrical power emissions through the radiotracer in your body.
Except for intravenous injections, most nuclear medicine methods are pain-free. Reviews of substantial pain or Unwanted side effects are uncommon.
