Each chapter closes with Critical Thinking Questions (listed below) as a review of chapter material that focuses on the role of the medical assistant.

1. What are the differences between invasive and noninvasive diagnostic radiology tests?

2. In general, what preprocedure care should be given to patients for whom radiology procedures have been ordered?

3. When scheduling a patient for an MRI, you must note whether the patient has any internal metallic elements (such as a pacemaker, clips, pins, shrapnel, etc.). Explain why this information is important.

4. A patient who is scheduled for a series of x-rays tells you he is concerned about the amount of radiation he will be receiving. What would you say to ease this patient's fears?
