What to Expect
Nuclear imaging can n=be done in a hospital or in
an outpatient healthcare facility. An electrocardiogram
is usually taken before nuclear imaging begins. An
IV, or intravenous catheter, is placed in the arm
to administer the tracer. The patient lies on his
or her back on a padded table under a camera. A small
amount of tracer is injected into the catheter, and
then the camera moves, capturing images at different
angles or rotating slowly around the patient.
Pre Test Guidelines
Patients are advised to avoid the following prior
to nuclear imaging:
· Drinking alcohol
· Drinking caffeinated beverages
· Taking nonprescription medications
In some instances, patients may be asked to discontinue
a prescription medication.
Risk Factors for Possible Complications
Nuclear imaging is not advisable for pregnant or nursing
Nuclear imaging scans are usually completed in 4 to
Complications associated with nuclear imaging include
a slight risk of developing angina or arrhythmias.
Post Test Guidelines
Patients are instructed to drink fluids to help flush
the radioactive tracer.

About Nuclear Imaging
During nuclear imaging, a small dose of a radioactive
isotope is injected into the bloodstream. The radioisotope,
or tracer, is carried through the bloodstream and
into the myocardium, of heart muscle. Special cameras
detect the radiation released from the tracers and
record information about the heart muscle and blood
flow. This information is then used to produce images
of the heart on a computer screen or film. The radioactive
isotopes used in nuclear imaging lose their radioactivity
quickly and typically pass from the body within 24
Among the types of nuclear imaging are:
· Myocardial perfusion scan which is used to
evaluate blood flow
· Radionuclide ventriculography which measures
ejection fraction, stroke volume, and cardiac output.
