MedicExchange Positron Emission Tomography (PET) Directory

In nuclear medicine, Positron Emission Tomography is an imaging technique of utilization of computerized radiography to check up metabolic activity in diverse tissues, particularly in the brain, but PET imaging is even used to map out heart functions.

PET scans generate 3 dimensional pictures of functional body processes. PET scanning is utilized a lot in clinical oncology and for analysis of diffuse brain damage/diseases causing different types of mental deterioration/dementia.

For PET scan imaging, radioactive isotopes tracers, usually fluorodeoxyglucose (FDG) is used. FDG chemically integrates into biologically active molecules, but other isotope tracers are even utilized than FDG, to image tissue concentration. FDG is injected through blood stream, and with waiting period of about an hour, the active molecules get concentrated in tissues to facilitate for the analysis.

On PET scan, the scanner distinguishes out gamma rays released obliquely by positron emitting radionuclide (isotope tracer) introduced in, on physically active molecule. 3 dimensional pictures of tracer concentration in body are reconstructed by computer analysis.

In contemporary scanners, 3d imaging is repeatedly attained with CT X-ray scan on the same medical session, with similar device, and patients are not required to change position, in between. This registers different sets of images, precisely - irregularity on PET scanning can be mutually related with structure on the computed tomography images.

PET scans are also read in conjunction with MRI, as the amalgamation yields both metabolic and anatomic information. Though PET scan images can be acquired through traditional dual head gamma camera fixed with coincidence detectors, the best possible PET imaging can be carried out through dedicated PET Products, only.
