A Gamma Camera is a device, which is used as an imaging technique to produce functional scans of the brain, lungs, thyroid, liver, skeleton, gallbladder and kidneys. This technique is known as Scintigraphy. Large crystal of sodium iodide is used to detect the gamma photons. Whenever gamma photon hits the crystal, it gives a tiny flash of visible light. Photomultipliers picked the gamma photons to convert the flash into an electrical signal. The computer then evaluates electrical signals from the photomultipliers to construct an image. It is a painless, minimally invasive way to obtain a complete image that is highly helpful in the treatment that follows.
The Gamma Camera will track the radioisotope in the area to be scanned and will measure how the part processes it.
At Molecular, we undertake the following Gamma scans:
Gamma Scanning has some benefits and risks
The benefits of having a scan done under scintigraphy to help diagnose a medical condition, or to check the symptoms of an existing condition, usually outweigh the risks, however, some of the potential risks are:
