What is Magnetic Resonance Imaging (MRI)?
Magnetic resonance imaging (MRI) is a noninvasive medical test that helps physicians diagnose and treat medical conditions.
MRI uses a powerful magnetic field, radio frequency pulses and a computer to produce detailed pictures of organs, soft tissues, bone and virtually all other internal body structures. The images can then be examined on a computer monitor, transmitted electronically, printed or copied to a CD. MRI does not use ionizing radiation (x-rays).
Our Philips Achieva 1.5T A-Series MRI machine offers 8 channel receivers. This delivers detailed MR images that allow physicians to better evaluate various parts of the body and determine the presence of certain diseases that may not be assessed adequately with other imaging methods such as x-ray, ultrasound or computed tomography (also know as CT or CAT scanning).
How do I prepare for my MRI exam?
Very little preparation is required. You may eat, drink, and take your medications. Prior to the scan, you will be encouraged to use the restroom.
You will be asked to complete a questionnaire before your MRI exam. Because of the potential harmful effects associated with some metallic objects in a magnetic field, you should tell the technologist performing your exam if you have had any surgeries, or if you have a pacemaker, aneurysm clips, metal in your eyes, metal implants in your ears, an implanted drug infusion device, shrapnel or bullet wounds, or permanent eyeliner.
If you have ever been a metal worker, you may be required to have special x-rays before your exam to make sure there are no metal fragments in your eye(s).
Tell your doctor if you are, or suspect you might be pregnant.
You will be asked to remove all metallic items from your person, such as watches, jewelry, hairpins, eyeglasses, and hearing aids. Also, do not take credit, bank, or parking cards with you into the scanner - the magnet will erase the information recorded on the metallic strip. An area for the safekeeping of your valuables is provided outside the scanner area.
What can I expect during my MRI exam?
A registered technologist will discuss the procedure with you and answer any questions you might have. A radiologist will review your medical history and then tailor the MRI study specifically for your medical problems.
You will be positioned on the MRI table by the technologist. A device called a coil may be placed over or wrapped around the area to be scanned. You will then be positioned under the magnet.
You will hear a tapping noise as the MRI scans are taken. You will be offered ear plugs or headphones to reduce the noise. It is very important to hold completely still while the scan is being performed. At all times, the technologist will be able to see you and communicate with you on a two-way intercom. Most procedures take from thirty to sixty minutes.
For some exams, contrast will be injected into a vein in your arm during the procedure to enhance the images. The contrast used for MRI does not contain iodine.
The technologist will show your examination to the radiologist, and additional images will be obtained if needed.
What will happen following my MRI exam?
After your MRI exam, you may resume your normal activities, diet, and medications unless instructed otherwise by the technologist or your doctor. Any contrast given for your exam will be eliminated in a day or two.
Your examination will be reviewed by the radiologist after the exam has been completed and results will be sent to your doctor.
