• During the C.T. examination the patient will lie on a cushioned table, which will
move through a large donut shaped x-ray machine.

during the CAT scan that the patient remains as still as possible.
• The technologist will ask the patient to hold their breath for several brief seconds. • The technologist directly watches the patient through an observation window
during the procedure for patient safety.
10. How long does the test take? Be prepared to be at the hospital for 1 hour. 11. Tell your doctor if you… Have a history of having an allergic reaction to IV contrast as your doctor may want to prescribe a medication for you to take prior to the procedure. 12.
