What is a chest, abdomen or pelvis MRI?
Magnetic resonance imaging, or MRI, is a method of producing detailed pictures of organs and body tissues by exposing a patient to radio waves in a strong magnetic field. The field is measured and analyzed by a computer, which forms two- or three-dimensional images that may be viewed on a monitor. Because it uses radio waves and a magnetic field rather than x-rays, there is no exposure to radiation. A chest, abdomen or pelvis MRI povides information on the heart and lungs, abdomen and pelvis that could not otherwise be detected from an x-ray, ultrasound or computed tomography (CT) scan.
Why might my doctor recommend an MRI of the chest, abdomen or pelvis?
An MRI is often used to clarify previous x-rays or CT scans. Your doctor might recommend an MRI of the chest to detect abnormal growths including cancer and the stages of cancer growth. An MRI of the chest also can reveal diseased heart valves, disorders of the ribs and sternum and early breast cancer.
How should I prepare for an MRI of the chest, abdomen or pelvis?
On the day of the procedure, wear comfortable clothing and try to relax. Before the procedure begins you will be asked if you have any metal medical equipment in your body such as a pacemaker, intrauterine device (IUD), implanted port or infusion catheter. Due to the strong magnetic fields created by MRI, these devices may interupt the procedure. Also, make sure to notify the technologist if you might be pregnant. Before the procedure begins you also will be asked to remove any metal jewelry or metal external objects as they may interfere with the procedure.
How is an MRI of the chest, abdomen or pelvis performed?
You will be asked to lie on your back on a cushioned table. A device called a coil will be placed on the area to be scanned. Coils are antennas used in every scan to help image the area of interest. Different coils are designed for different parts of the body and will conform to your shape as your are being imaged. You will not experience any discomfort from the coil.
After you are positioned, the table will move under the magnet. The radiologic technologist will leave the room once the procedure begins to control the equipment and perform your scan. You will be able to communicate with the technologist through an intercom during the procedure. The machine will make a slight rapping sound as the images are being taken. In between scans the machine is quiet. The process takes between 30 and 45 minutes and is painless.
What type of equipment is used for an MRI of the chest, abdomen or pelvis?
An MRI can be performed in either a closed or an open MRI scanner. A closed scanner requires you to lie in a clylinder-like compartment. An open MRI is ideal for claustrophobic, pediatric, elderly, and large patients. This procedure uses a scanner that is less confining. Both types of scanners can provide your physician with accurate and detailed images of your chest.
Will I experience any side effects from an MRI of the chest, abdomen or pelvis?
In some cases, the radiologist may request a contrast agent (dye) to improve the quality of the images. The agent is designed to make organs and blood vessels more visible, and will likely cause no side effects. You may experience a metallic taste your mouth and in rare cases might experience more serious side effects. The technologist can answer any questions about possible side effects.
How will I get the test results of my MRI of the chest, abdomen or pelvis?
The results of a chest MRI are read by the radiologists of Professional Radiology, Inc. A detailed report will be sent to the refferring physician of the patient within a few days.
