Principles of PET • Inject a radioactive tracer bind with glucose • The active part of brain absorbs it more than other inactive parts • The radioactive tracer is: Fluorine-18-deoxyglucose (FDG), a radionuclide labeled glucose analogue is injected into the organ that would be imaged 8 By Eng. The test accurately details the size, shape, and function of the brain. Basics Principle The basic principle behind CT is that the internal structure of an object can be reconstructed from multiple projections of the object. Basic principles of CT scanning 1.

Summary• PET scan is very good imaging technique used in both medicaloncology and brain imaging.• This scan is most effective due to its lesser time of completionand better resolution and also less exposing to radioactivitythan CT scan, high accuracy in detecting brain diseases (at veryearly stage too )and prediction of various strokes.• Basic Principles of CT Scanning. Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. By identifying changes at the cellular level, PET may detect the early onset of disease before other imaging tests can. Computed tomography (CT) and magnetic resonance (MR) imaging rely on anatomic changes for diagnosis, staging, and follow-up of cancer. It is very similar to conventional nuclear medicine planar imaging using a gamma camera (that is, scintigraphy), but is able to provide true 3D information. A PET scan for brain tumors can identify brain tumors and will give you an idea of what exactly is happening and how it can be treated. In positron emission tomography (PET), the two photons from the annihilation of positrons originally emitted from the radiotracer are the basis of image formation as these are detected by the system in coincidence. • Radioactive tracer decays by Positron Emission.
