MRI Procedure Introduction

Although there are other imaging methods such as x-ray, ultrasound or computed tomography (also called CT or CAT scanning), the detailed MR images allow physicians to better evaluate parts of the body and certain diseases that may not be assessed adequately with other methods. These other methods are usually less expensive but may not be appropriate for your medical testing needs. The decision on the use of an alternative testing method should be based on a discussion with your physician.

There are numerous types of MRIs, each of which are performed in the same manner. Some may need to be performed with contrast (a dye which is injected), without contrast, or with and without contrast. Costs do vary per type of MRI and can be determined through the NewChoiceHealth.com website.

MRI Procedure Patient Preparation

Guidelines about eating and drinking before an MRI exam vary at different facilities. Unless you are told otherwise, you may follow your regular daily routine and take medications as usual. If you have claustrophobia (fear of enclosed spaces) or anxiety, you may want to ask your physician for a prescription for a mild sedative or request to have the MRI procedure performed in an open-sided MRI machine which may impact the cost of the procedure. All metallic items and items with magnetic strip should be left at home if possible, or removed prior to the MRI scan.

You should tell the technologist if you have metal or electronic medical devices in your body!

What to expect during and after an MRI procedure

Most MRI exams are painless. You will be positioned on the movable examination table. Some patients, however, find it uncomfortable to remain still during MR imaging. Straps and bolsters may be used to help you stay still and maintain the correct position during imaging. It is normal for the area of your body being imaged to feel slightly warm, but if it bothers you, notify the radiologist or technologist. It is important that you remain perfectly still while the images are being recorded. MRI exams generally include multiple runs (sequences), each typically a few seconds to a few minutes at a time. The entire examination is usually completed within one hour. If a contrast material will be used in the MRI exam, a nurse or technologist will insert an intravenous (IV) line into a vein in your hand or arm. It is normal to feel coolness and a flushing for a minute or two when the contrast material is injected. If you have not been sedated, no recovery period is necessary. You may resume your usual activities and normal diet immediately after the exam.
