The Radiology and Imaging department offers a
range of nuclear medicine procedures.
Technologists are certified by the American Registry of Radiology
Technologists (ARRT) and the state of Texas. All registered and
licensed health care professionals administer diagnostic tests
under the supervision of a radiologist on the medical staff.
Nuclear medicine provides clinicians with information and images
of the structure and function of organs that cannot be obtained
by other methods. A subspecialty within the field of radiology,
nuclear medicine or positron
emission tomography (PET) uses very small amounts of
Nuclear medicine procedures are noninvasive and are performed to:
- Analyze kidney function
- Visualize heart blood flow and function (such as a myocardial
- Scan lungs for respiratory and blood flow problems
- Identify blockage in the gallbladder
- Evaluate bones for fracture, infection, arthritis and tumors
- 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
- Investigate abnormalities in the brain
Nuclear imaging uses radioactive materials called a
radiopharmaceutical or radiotracer, which is injected into a vein
or swallowed and then travels to the intended organ. A special
gamma camera records this radioactivity in the form of images.
The camera works together with a computer to measure the amount
of radiotracer absorbed by your body and produce special pictures
offering details on both the structure and function of organs and
other internal body parts.
- The information provided by nuclear medicine examinations is
unique and often unattainable using other imaging procedures
- Nuclear medicine scans can provide information helpful in the
development of a care plan
- Nuclear medicine is physically less traumatic than
Nuclear medicine images can be superimposed with computed
tomography (CT) or magnetic resonance imaging (MRI) to produce
special views leading to more precise information and accurate
diagnoses. Nuclear medicine also offers therapeutic procedures
for medical conditions affecting the thyroid gland.
