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.
Computed Tomography (CT)
Computed Tomography (CT), also known as a CAT scan, is a sophisticated imaging technique that shows different levels of the anatomy. During CT imaging, the x-ray source rotates around the patient. Each rotation produces a single, cross-sectional "slice", like the slices in a loaf of bread. These images are far superior in detail than standard x-rays and greatly enhance a physician's diagnosis.
CT is used to diagnose many conditions. In cancer detection, CT is used to scan for abnormal masses, showing the size and shape of the tumor, its precise location and whether it is solid or hollow. In addition, CT scans can provide valuable information in the detection of abscesses, strokes, head injuries and bleeding inside the skull.
