Nuclear medicine is a valuable tool for the diagnosis of diseases. If a non-invasive and inexpensive to the details of how a potential organ and the organ structure for the diagnosis of certain diseases and disorders much earlier than other imaging methods provide. The amount of radiation in a nuclear medicine procedure involved is generally much lower than the radiation from a conventional X-ray makes this process very safe.
Nuclear medicine works by introducing a low-level chemical or radiotracer in the body by intravenous injection, inhalation or ingestion. The radiotracer is specially formulated to temporarily examined in the specific organ or tissue will be accumulated. The radiotracer emits gamma radiation signal is picked up and read by a gamma camera in one image the story of the function of the organ results says. “Hot spots” show a greater accumulation of radiotracer demonstrates an increase in activity. Can detect “cold spots” decreased activity. Nuclear medicine may provide information to the other imaging methods is to miss the test tissues at the molecular level.
