Radioactive nuclei that are injected into a patient collect at certain sites within their body,undergoing radioactive decay and emitting electromagnetic radiation. These radiations can then be recorded by a detector. This procedure provides an important diagnostic tool called:
- AGamma camera
- B$CAT$ scan
- CRadiotracer technique
- DGamma ray spectroscopy
