Testing procedure[ edit ] The examiner typically begins polygraph test sessions with a pre-test interview to gain some preliminary information which will later be used to develop diagnostic questions. Then the tester will explain how the polygraph is supposed to work, emphasizing that it can detect lies and that it is important to answer truthfully. Then a "stim test" is often conducted:
The drugs could cause blood to flow more effectively to unobstructed areas, leaving problem areas without blood. In rare cases, this could lead to a heart attack. Anyone who has unstable angina or other cardiac instability may not be a suitable candidate to receive these drugs.
Radiation risk Concerns have also been raised about the levels of radiation that a person is exposed to during nuclear medical tests, and whether or not this increases the risk of cancer.
Both the numbers of tests and cancer rates have risen in recent years, but it remains unclear whether they are linked. The risk will depend on the age and sex of the patient, their existing health condition, the dose used, and precautions taken.
Doctors are urged to used nuclear tests only if necessary.

Patients with diabetes must follow their doctor's instructions before and after the test. Women should inform the doctor if she is, or could be, pregnant, or if she is breastfeeding.
