Nuclear Medicine Scan
Gammagrafía (Medicina Nuclear)
Also: Estudio de Medicina Nuclear (regional variant)
What it means
A nuclear medicine scan is a method that uses radioactive substances to make pictures of areas inside the body, according to the National Cancer Institute (NCI) dictionary, which adds that it is also called radioimaging. MedlinePlus, which titles its page Nuclear Scans, describes a nuclear scan as a type of medical imaging test that uses a small amount of radioactive material, called a radiotracer, and that shows how organs and tissues are working, not just what they look like. The radiotracer may be given as an injection, a pill or liquid to swallow, or a gas to inhale. Afterward, a special camera detects the radiation coming from inside the body. MedlinePlus says nuclear scans are commonly used to perform bone scans and to evaluate the thyroid.

No cited page prints the headword Gammagrafía (Medicina Nuclear) in that exact form. MedlinePlus en español titles its page Escanografía nuclear and gives Gammagrafía as another name; the National Cancer Institute's Spanish dictionary enters the term as exploración de medicina nuclear and says it is also called radioimaginología. The Spanish dictionary defines gammagrafía, a feminine noun, as a radiological technique that records the gamma radiation emitted by an organ to which a substance emitting that radiation has first been given.
MedlinePlus en español calls the radiotracer trazador radiactivo and names una gammacámara among the imaging devices. Bone scans are gammagrafías óseas, and the specialist who reviews the images is radiólogo. The NCI Spanish dictionary speaks of sustancias radiactivas and of images made by una máquina especial. The same MedlinePlus en español page keeps the abbreviations SPECT and PET for two kinds of scanner.
