What is an MRI?
"MRI" stands for Magnetic Resonance Imaging, one of the most advanced imaging technologies currently in use for diagnostic radiology procedures. MRI uses strong magnetic fields and radiofrequency coils to produce cross sectional images of the body to help diagnose certain medical conditions.
MRI has been used in the medical community since the 1960’s, and since that time, its use as an imaging modality has expanded to virtually every aspect of medicine. In Radiology, MRI is used to image the brain and spine, the major joints such as the shoulder and knee, and now, with more powerful magnets and faster technology, the heart and blood vessels.
An MRI magnet (Figure 1) consists of an exam table for the patient and the scanner itself, which resembles a short tunnel with both ends open to allow air and light to come inside. There is also a tool for injecting contrast should your exam require it. Some exams require a contrast agent (see Gadolinium below) to highlight certain parts of the body under evaluation.
How do I prepare for the exam?
There is usually no need for advanced preparation for an MRI exam. As mentioned above, please make us aware of any metal implants you may have before being taken into the room where the scanner is located.
It is also advisable to not bring any metal objects such as watches, jewelry, or credit cards to the exam, as they are not allowed in the room. Note that eye makeup may also contain metal fragments, and should not be used the day of the exam.
Again, please make us aware if you are pregnant or think you might be, or if you may need sedation for claustrophobia.
How do I get my exam results?
Trained and experienced radiologists and cardiologists will interpret your exam, and then report the results to the physician who originally ordered the exam. Your physician will then give the results to you.
Please feel free to ask us any questions you may have at the time of the exam. Our technologists and radiologists will be happy to answer any questions you may have about the procedure.
