Patients feel humiliated when they are naked or partly naked and do not know what is expected from them. A smile and a short explanation can help. Hospital gowns should not be flimsy, and gowns and blankets should be clean. It is sometimes difficult to climb on the patient couch, and even more difficult to get down after the examination. Many patients need help, even if they don't look fragile or incapacitated.
Patients sometimes vote with their feet against certain radiological equipment.
This is the exception, however, rather than the rule. Worrying about an examination's outcome is common, yet there are reasons why radiologists will not disclose results to a patient and won't talk to the patient at all. But patients need to know when the result will be available, and to whom it will be communicated. Many people prefer hamburger joints to restaurants. Eating fast food is more time efficient and cheaper.
