WHAT IS NUCLEAR MEDICINE?
Nuclear
medicine involves the use of small amounts of radioactive
materials (or tracers) to help diagnose and treat a variety of
diseases. Nuclear Medicine determines the cause of the medical
problem based on the function of the organ, tissue, or bone. This
is how nuclear medicine differs from an x-ray, ultrasound, or
other diagnostic test that determines the presence of disease
based on structural appearance.
As
an integral part of patient care, nuclear medicine is used in the
diagnosis, management, treatment, and prevention of serious
disease. Nuclear medicine imaging procedures often identify
abnormalities very early in the progression of a disease-long
before some medical problems are apparent with other diagnostic
tests. This early detection allows a disease to be treated early
in its course when there may be a more successful prognosis.
Today,
nuclear medicine offers procedures that are helpful to a broad
span of medical specialties, from pediatrics to cardiology to
psychiatry. There are nearly one hundred different nuclear
medicine imaging procedures available and not a major organ
system, which is not imaged by nuclear medicine.
HOW DOES NUCLEAR MEDICINE
WORK?
Nuclear
medicine uses very small amounts of radioactive materials or
radiophamaceuticals to diagnose and treat disease. These tracers
are introduced into the body by injection, swallowing, or
inhalation. Radiopharmaceuticals are substances that are
attracted to specific organs, bones, or tissues and are used to
study different parts of the body. The radiopharmaceuticals used
in nuclear medicine emit gamma rays that can be detected
externally by special types of cameras called gamma cameras.
IS NUCLEAR MEDICINE SAFE?
Nuclear
medicine procedures are among the safest diagnostic imaging exams
available. A patient only receives an extremely small amount of a
radiopharmaceutical, just enough to provide a sufficient
diagnostic information. In fact, the amount of radiation from a
nuclear medicine procedure is comparable to, or often times less
than, that of a diagnostic x-ray.
Does
the tracer cause side effects? Adverse reactions, or side
effects, are extremely rare, but do let the technologist know if
you experience any symptoms during or after the tracer injection.
-
Bone scans to examine
orthopedic injuries, fractures, tumors, or unexplained bone
pain. Bone scans may also be ordered for follow-up cancer
patients.
-
Heart scans to identify
normal or abnormal blood flow to the heart muscle, measure
heart function or determine the existence or extent of damage
to the heart muscle after a heart attack.
-
Breast scans which are used
in conjunction with mammograms to more accurately detect and
locate cancerous tissue in the breasts.
-
Liver and gallbladder scans
to evaluate liver and gallbladder function.
-
Renal imagining to examine
kidney function.
-
Thyroid uptake and scans to
analyze the overall function of the thyroid and show the
structure of the gland.
-
Lung scans to evaluate the
flow of blood and movement of air into and out of the lung as
well as determine the presence of blood clots.
-
Gastrointestinal bleeding
scans
These are just a
list of the most common procedures that we perform
Please
ask when scheduling your examination if there is any special
preparation. Certain tests may require some slight preparation,
varying from fasting six hours prior to the exam, to being well
hydrated, to no prep at all.
You
should tell your doctor if you are pregnant or think that you are
pregnant. You should also tell your doctor if you are
breastfeeding.
WHO PERFORMS NUCLEAR
MEDICINE TESTS?
A
nuclear medicine technologist, a health care professional trained
and experienced in the theory and practice of nuclear medicine
procedures, performs the test by administering the tracer,
positioning the patient under the camera and operating the
equipment used in the test. Our technologists are certified and
are well educated in the field of Nuclear Medicine. All of our
technologists have attended respectable colleges to attain their
certification. Each employee has been through rigorous exams and
has spent hundreds of hour in training. You can be sure that when
you are with the Nuclear Medicine technologists you are in good
hand.
The
amount of time needed for a procedure depends on the type of
test. Nuclear Medicine tests are performed in three parts: tracer
administration, taking the pictures, and analyzing the images.
For many tests, a certain amount of time is needed for the tracer
to accumulate in the part of the body being studied before the
pictures can be taken. During the imaging session, the time
needed to obtain the pictures (from minutes to hours) will vary
depending on the test.
- You may resume your daily
activities after your nuclear medicine examination.
- The tracer you are given will
remain in your body for a short period of time and is cleared
from the body through natural bodily functions. Drinking
fluids will help eliminate the tracer more quickly.
- A Board Certified Radiologist
will interpret the images from your exam.
- Examination reports will be
faxed to your doctor within 48 hours of your examination
