Imaging modalities Part 4 Flashcards
a medical specialty that focuses on the use of radioactive materials called radiopharmaceuticals for diagnosis, therapy, and medical research.
Nuclear medicine
Determine the cause of a medical problem based on organ or tissue function (physiology).
Nuclear medicine
generally introduced into the body by injection, swallowing, or inhalation.
Radioactive tracer
Different tracers are used to study different parts of the body.
Radioactive tracer
selected that localize in specific organs or tissues.
Radioactive tracer
selected carefully to provide the lowest amount of radiation exposure to the patient and still ensure a satisfactory examination or therapeutic goal .
Radioactive tracer
produce gamma-ray emissions from within the organ being studied.
Radioactive tracer
A special piece of equipment, known as a gamma or scintillation camera, is used to transform these emissions into image that provide information about the function and anatomy of the organ or system being studied
Radioactive tracer
An electronic device that detects gamma rays emitted by radio pharmaceautical that have been introduced into the body as tracers.
Radioactive tracer
The camera records this information on a computer or on film
Radioactive tracer
Measure the density or thickness of bones
Bone densitometry
It measures the amount of mineral (calcium) in a specific area of the bone.
Bone densitometry
The bone measurement values are used to assess bone strength, diagnoses diseases associated with low bone density (especially osteoporosis), monitor the effects of therapy for such diseases, and predict risk of future fractures.
Bone densitometry
The more mineral in the bone measured, the greater is the bone density or bone mass.
Bone densitometry
Measure the density of bones
BMD test
