The most effective way to limit radiation exposure to the pregnant patient is to discuss with the referring clinician the indication and necessity for any examination. Alternative procedure, including nonionizing imaging procedure such as ultrasound or magnetic resonance imaging, should be considered. If an X-ray or CT scan is deemed necessary, the imaging technologist and the imaging physician should work together to assure the best benefit/risk for the patient and conceptus. Establishment of guidelines for imaging acute disease processes in pregnant patients can expedite patient evaluation.
