Cardiovascular nuclear medicine.

Exciting developments in radiopharmaceuticals and instrumentation have established the field of cardiovascular nuclear medicine as an extremely useful clinical tool. Depending on the patient's problem, one may elect to perform myocardial perfusion images with 201Tl, infarct avid images with 99m Tc, or wall motion and other functional studies with multiple gated acquisition techniques. Often, a combination of these studies is useful in elucidating a particular problem.
