Riverhead NY Patients Learn about the PET CT

The Positron Emission Tomography-Computed Tomography is a specialized scanning device that handles nuclear medical imaging.

What PET CT Does

Riverhead NY patients can have a PET scan done that is safe and non-invasive. These scans are generally painless, though there are a few exceptions, such as intravenous injections and it can help your doctor find problems and diagnose them correctly.

The radioactive materials used are called radiotracers and these small materials are injected, inhaled or swallowed into the body to accumulate in a specific area that needs to be tested.

In order for your procedure to be called a PET CT scan, the same process is completed as for the PET scan and then the images are superimposed with CT (computed tomography) or MRI (Magnetic Resonance Imaging) that allows special views to be shown. These views show two different exams (the PET and a CT or MRI) to be shown as one image, providing more information and better diagnoses.

In essence, the PET scan will measure your body functions, including oxygen use, blood flow and how you metabolize sugar, which will help your doctor determine how well your body uses these things. Likewise, the CT imaging uses specialized equipment to produce many inside pictures of your body that are then used by a radiologist to provide important information.
