X-ray
The ionizing electromagnetic radiation emitted from a highly evacuated tube,
resulting from the excitation of the inner orbital electrons by the bombardment
of the target anode with a stream of electrons from a heated cathode. Ionizing
electromagnetic radiation produced by the excitation of the inner orbital electrons
of an atom by other processes, such as nuclear delay and its sequelae.
What is General Nuclear Medicine?
Nuclear medicine is a subspecialty within the field of radiology.
It comprises diagnostic examinations that result in images of body
anatomy and function. The images are developed based on the detection
of energy emitted from a radioactive substance given to the patient,
either intravenously or by mouth. Generally, radiation to the patient
is similar to that resulting from standard x-ray examinations.
Common uses of the procedure?
Nuclear medicine images provide very detailed imaging of certain organs
and can assist the physician in diagnosing diseases. Tumors, infection
and other disorders can be detected by evaluating organ function. Specifically,
nuclear medicine can be used to:
Analyze kidney function
Image blood flow and function of the heart
Scan lungs for respiratory and blood-flow problems
Identify blockage of the gallbladder
Evaluate bones for fracture, infection, arthritis or tumor
Determine the presence or spread of cancer
Identify bleeding into the bowel
Locate the presence of infection
Measure thyroid function to detect an overactive or under-active
thyroid
