Meaning and Definition
A specialized medical imaging device that uses a gamma radiation detector to create pictures of the internal distribution of radioactive substances in the body.
In nuclear medicine, a stationary or moving device that captures images (scintigrams) of organs or tissues after a patient is given a small amount of a radioactive tracer. The term can also refer more broadly to the imaging system, including the detector and computer.

- Writing it without a hyphen as a single word 'gammacamera'.
FAQ
Frequently Asked Questions
No, they are related but different. A gamma camera is often used for planar imaging or SPECT (Single Photon Emission Computed Tomography), detecting single gamma photons. A PET (Positron Emission Tomography) scanner detects pairs of gamma photons produced by positron annihilation.
The radiation dose from the tracer used in a gamma camera scan is generally low and considered safe for diagnostic purposes, with benefits outweighing risks. The camera itself does not emit radiation; it only detects it from the patient.
In highly informal or jargon-filled technical speech, it might be used verbally (e.g., 'We need to gamma-camera the liver'), but this is non-standard. The correct phrasing is 'to perform a gamma camera scan' or 'to image with a gamma camera'.
The term was coined in the mid-20th century following the invention of the scintillation camera by Hal Anger in 1957. 'Gamma' refers to the type of electromagnetic radiation detected, and 'camera' is used by analogy to a photographic device that records an image.
