MRI images are formed when signals, emitted by body tissue, are processed by software and turned into clinical images. These signals are generated using a safe magnetic field in combination with radio waves of a specific frequency. Different tissue characteristics are revealed through this process and translated into different contrast levels on the image.
A typical procedure averages 30 minutes, or longer depending on the type of information required by your physician. You can help to make your images spectacular by simply relaxing and remaining as still as possible during the exam. In fact, some patients fall asleep during the MRI exam.
During your MRI examination, a technologist will be with you and will be able to see you at all times. For your convenience, an intercom system is built into the MR imager so that if you need anything, the technologist will be right there.
In certain instances, a contrast agent may be administered to enhance the study. There are no extra precautions if your physician requires this type of study. Consult the physician or technologist if you have any questions.
