Though some details from non-medical trials have advised imaging as early as 6 weeks subsequent an try at definitive surgical resection for HNC, the NCCN endorses surveillance (re-staging) PET-CT 12 months after such an try.
The pc workstation that processes the imaging facts is within a different Manage place. This is where the technologist operates the scanner and screens your Test in direct visual Call. The technologist will be able to listen to and talk to you employing a speaker and microphone.
A positron emission tomography (PET) scan is surely an imaging check that will help reveal the metabolic or biochemical function of your body's tissues and organs. The PET scan utilizes a radioactive drug identified as a tracer to point out each typical and atypical metabolic activity.
What exactly is a PET Scan? A PET scan is really a clinical imaging method that takes advantage of radioactive substances, known as radiotracers, to visualise and measure alterations in metabolism (the chemical procedures that take place in cells to help keep the human body working Commonly).

Within the day in the Test, the affected person rests lying for at least fifteen min, so that you can silent down muscular action, which could be interpreted as irregular metabolism.
As unstable eighteen-File decays, it releases positrons. Within about 2 mm of journey from their origination web-site in tissue, positrons collide with electrons and launch gamma energy (photons). The photons strike scintillator crystals housed in a device that encircles the individual. Crystals Utilized in modern-day imaging equipment vary by producer, Each and every with its possess photon detection generate and determination; a standard crystal type used for PET is lutetium oxyorthosilicate. The crystals transmit the photoelectric energy into circuits that convert the electric Power into Personal computer knowledge.
