Positron Emission Tomography (PET)
PET represents the very latest innovation in nuclear medicine, merging cutting-edge medical science with comprehensive computer technology. While x-rays, MRI’s, CT’s, and mammograms are limited to visualizing actual damage to the body’s anatomical structure, PET focuses on the body’s metabolic process, allowing for the detection of disease long before any damage occurs.
PET has already established itself as an invaluable tool in diagnosing coronary artery disease. With a single session, PET can help facilitate prompt cancer treatment of the lungs, prostate, breast, colon, head and neck, pancreas, esophagus and ovaries.
Perhaps the most exciting revelation has been using PET to study brain disorders. PET has uncovered a remarkably consistent pattern in the diagnosis of Alzheimer’s disease and other dementia, Parkinson’s disease, and seizure disorders.
PET measures the body’s metabolic activity. A patient receiving a PET scan is injected with FDG about an hour before the scan. The FDG, which is a form of radioactive glucose, is metabolized by the body and emits gamma rays, which are picked up by the PET scanner. Then, a computer reassembles the signals into images. Doshi Diagnostic is proud to have one of New York’s first Philips Allegro High Performance PET scanners. It boasts a wide variety of revolutionary developments, including exceptionally accurate 3D imaging reconstruction, multi-modality connectivity for image fusion, higher resolution imaging detectors, and the fastest total body imaging time of any PET system currently available.
