The patient will be asked to perform certain actions such as lying absolutely still or holding their breath. This is done to ensure the quality and accuracy of the image. The magnet, because of its design, and the principals behind the technology, can get rather loud. RF coils are used to increase the quality of the image. A microphone is installed in the magnet so that you and the technologist can communicate, so if you feel any unusual sensations or discomfort please let the technologists know right away.
Claustrophobia is the fear of small enclosed spaces.
This is when the person verbalizes he or she does not like something similar to an elevator. This person will walk up many flights of stairs, will not ride as a passenger in a car and will not stay in a room without a door being open. Physical manifestations of claustrophobia include choking sensations, shaking, faintness, nausea, vomiting and numbness. These symptoms occur unexpectedly and usually last a few minutes. Before your scan, you will be asked a number of questions some of which will be to assess whether you are claustrophobic or not.
