Positron emisjons tomografi (PET eller PET-scan) er en diagnostisk undersøkelse som gjør det mulig å fremstille fysiologiske bilder, det vil si bilder som viser aktivitet i celler og vev gjennom påvisning av positroner Apparatene som brukes gir en kombinasjon av PET (positron-emisjonstomografi) og CT (computertomografi). Bilder fra PET-skanning vil avsløre opphopning av celler i høy aktivitet, slik som kreftceller. CT-skanning viser hvor i kroppen denne opphopningen befinner seg, samt omfanget av dette. I det kombinerte apparatet skjer det en automatisk bildesammensmelting mellom PET- og CT-bildene - og. PET er en undersøkelse der kroppen din blir skannet etter at du har fått injeksjon av radioaktivt merket sukker. Undersøkelsen bruker vi for å påvise ulike sykdommer. Det viktigste anvendelsesområdet er innenfor kreftmedisin (onkologi), men PET er også nyttig i kardiologi, nevrologi, revmatologi og ved infeksjonsproblematikk Hva er involvert i PET Scan Forberedelse?

Når positronene kolliderer med elektroner oppstår det glimt av gammastråling som etterhvert registreres som et. Senter for nukleærmedisin og PET inkluderer eit radiokjemisk laboratorium med ein partikkelakselerator, ein såkalla syklotron, til produksjon av radioaktive isotopar. Legemiddelet med radioaktive isotopar som vert nytta ved dei fleste PET/CT-undersøkingane ved senteret kallast F-18 FDG, dette er radioaktivt merka druesukker
The MRI is a lot worse, I think, than the PET scan. The tube is more open with the PET scan, but, all of these tests are still nerve racking.

CT scan (computer tomography) and PET scan (positron emission tomography) are different but related imaging techniques. A PET scan uses nuclear medicine imaging to produce a three-dimensional picture of functional processes in the body. PET scans provide metabolic information and are increasingly read alongside CT or MRI (magnetic resonance imaging) scans, which provide anatomic information PET scans create images which show where cells are particularly active in the body. It is most commonly used to diagnose cancer. Note: the information below is a general guide only.The arrangements, and the way tests are performed, may vary between different hospitals
The PET portion of this imaging modality relies on the accumulation of radioactive glucose analog, FDG. In cancer cells, there is an overproduction of glucose transporters and, as a result, increased FDG uptake. However, not all PET-positive lesions are cancer, and in many instances, PET findings can be false positive A positron emission tomography scan is known as a PET scan. PET scan is a type of test that may be used in cancer treatment. It can be done along with a CT scan. If so, doctors call it a PET-CT scan. But you might also just hear it called a PET scan A PET scan may reveal cancerous tissue not revealed by a CAT scan. Computed tomography (CT)utilizes X-rays taken from different angles and then processed by a computer to create a 3D, cross-sectional image of the body. CT scans produce more accurate and precise images than X-rays A positron emission tomography (PET) scan is a diagnostic examination used to detect cancer, determine the stage of cancer, and evaluate the effectiveness of cancer treatments, such as chemotherapy or radiation therapy. In a PET scan, radioactive sugar molecules are injected into the body. Cancer cells absorb sugar more quickly than normal cells, so they light up on the PET imaging. The CT exam takes place first, followed by the PET scan. On occasion, a second CT scan with intravenous contrast will follow the PET scan. For more information on how a CT scan is performed, see Computed Tomography. The CT scan takes less than two minutes. The PET scan takes 20-30 minutes. Total scanning time is usually about 30 minutes
PET is an acronym which stands for Positron Emission Tomography. Interpreting a PET scan is part of a branch of internal or nuclear medicine.. With PET imaging, a radiologist injects a small amount of radioactive dye into the patient and then measures the uptake of the dye as it passes through different parts of the body..

The special thing about PET: it shows how active the metabolism in certain tissues is.
