MRI: Frequently Asked Questions

Unlike x-ray exams, MRI does not use ionizing (x-ray) radiation. Instead, MR creates high-quality images through the combination of a strong magnetic field and radio waves.

The scanner is wide open on both ends, and well lit and -ventilated throughout. There is a call button and two-way intercom system so that you can communicate with the technologist at all times

MRI is very safe. There are no health risks associated with the magnetic field or the radio waves used by the machine nor have any side effects been reported. It is important to complete the safety-screening sheet prior to the procedure as some conditions may preclude you from having an MRI.

While an MRI scan has no known side effects, it is not recommended for pregnant women unless it is medically indicated. If you are pregnant or think you might be, please tell your doctor before scheduling your exam.

It is safe to have an MRI while breast feeding however if you are breast feeding and are going to have a gad injection, it is recommended you wait 48hrs after the injection before beginning to breast feed again.

The scanner works with strong magnetic fields, which builds up energy. The energy is released as loud knocking sounds.

The technologist will assist you to lie down on the cushioned exam table of the scanner and a device called a "coil" will be placed around the area of the body being scanned. When you are comfortably and safely positioned, the table will move into the magnet opening, bringing the area being imaged into the center of the magnet. The scanner resembles a tunnel with both ends open to allow air and some light inside. As the exam proceeds, you will hear a knocking sound for several moments at a time as the images are taken. It is essential to lie still during this part of the exam because even slight movements can affect image quality. To help you relax, our scanner is equipped with a music system. Depending on the area being imaged, examinations may take anytime from 30 minutes to 1 hour.

Although most people are able to tolerate this exam well, some become very anxious inside the scanner. If you know that you become very uncomfortable in small, enclosed spaces, please tell our staff or your physician before scheduling your exam. We will either schedule you for an open MRI exam, or schedule extra time to give you a mild sedative to help you relax. If you require this medication, please make arrangements for someone to drive you home. Patients can bring music CD's or listen to the radio and can have a friend or family member in the room with them.
