What is Nuclear
Medicine Imaging?
Nuclear medicine imaging is unique in
that it documents organ function and structure, in contrast to
diagnostic radiology, which is based upon anatomy. Nuclear medicine uses
very small amounts of radioactive materials or radiopharmaceuticals (radionuclides)
to diagnose and treat disease. Radiopharmaceuticals (radionuclides) are
substances that are attracted to specific organs, bones, or tissues. The
radiopharmaceuticals used in nuclear medicine emit gamma rays that can
be detected externally by specific types of cameras: gamma or PET
cameras. These cameras work in conjunction with computers used to form
images that provide data and information about the area of body being
imaged. The amount of radiation from a nuclear medicine procedure is
comparable to that received during a diagnostic x-ray.
Preparation For Having A Nuclear Imaging
Examination
Specific instructions should be followed
depending on the examination your physician has scheduled for you as
follows. If the exam you are to have is not listed below, then
there is no specific prep required. If you are pregnant or
suspect you may be pregnant, you must not have any nuclear imaging tests
without first consulting your physician.
