AHCI :: MRI Frequently Asked Questions

Will my entire body be inside the machine?
The part of the body that is scanned must be in the center of the MRI tunnel. If the body part being scanned is from the waist down, you will be placed in the tunnel feet first. If the body part being scanned is from the waist up, you will be placed in the tunnel head first.

Is the tunnel totally enclosed?
No. The tunnel is always open on both ends! Because of the position of the body, the ends of the tunnel might be seen from the scan position. There are lights in the tunnel and a fan blowing fresh air.

Will I be left alone during the test?
No. There will be a technologist on the unit with you at all times, and he/she can be reached either just by speaking out or by pressing the call button in an emergency.

Are there any needles involved?
Generally, most exams do not require an injection in order for the exam to be done. There are, however, some exams that do require an injection. These exams usually are looking for any post surgical changes in the spine, for tumors or for any types of small lesions in the brain or ear canals.

Are there any side-effects from an injection?
No. Patients can continue their daily routine after an MRI exam or an injection. Most contrast agents are excreted from the body when the patient urinates.

How long does an MRI exam take?
Most MRI exams take approximately 45 minutes to one (1) hour, but you should plan on being at the hospital for two (2) hours.

Why does it take so long for an exam?
An MRI exam looks at the body from many different angles without having to move the patient. Because there is so much information to gather, it takes the computer system time to record all of the details.

What should I do to prepare for an MRI exam?
It is very important to wear loose, comfortable clothing free of all metallic objects (zippers, snaps, rivets), and leave all jewelry and metallic hair ornaments and pins behind. There are no dietary restrictions for an MRI exam.

Am I allowed to do anything while the scan is occurring?
Due to the nature of the MRI machine, you must lie very quietly and still while the exam is going on. However, the MRI unit is equipped with a music system so that you may listen to the radio, or you can bring in a CD to listen to. Do not be afraid to speak to the technologist if you need anything.
