MRI ScanWhat Is a MRI Scan?Magnetic resonance imaging, commonly known as MRI is a medical test that aids physicians in diagnosis and treating medical conditions. This is a noninvasive and typically painless test. In contrast to the more common X-Ray that uses ionizing radiation, MRI uses a strong magnetic field, radio waves and a computer. This enables MRI to make very detailed pictures of bone, organs, soft tissues and any other body structures. The physician can then view the pictures on the computer for further evaluation. How Is MRI Performed?MRI test are typically done on an outpatient basis as they generally can be completed under 30 minutes. Patients are positioned on a moveable exam table. A coil containing small components that send and receive radio waves may be placed around the portion of the body being examined. If the patients particular procedure requires a contrast dye then the MRI technologist will insert an IV line into a vein in the hand or arm. The exam table will be gently moved into the MRI machine and the technologist will go to an adjacent room where they can perform the tests while watching the patient through a window. The MRI technologist will be able to communicate with the patient through a sound system at anytime. In addition, the patient will have headphones and will be able to listen to the type of music of their choice throughout their procedure. Once the exam is completed the technologist may ask the patient to wait while they check the images and determine if any additional pictures are required. If the patient needed an IV it will then be removed. How Should I Prepare for My MRI?Patients should wear comfortable clothes that are easy to change as they may be asked to wear a gown for their procedure. You may also be asked to remove any jewelry, eyeglasses or metal objects. Your physician will give any special dietary or medication instructions ahead of time if they are necessary. The physician and or MRI technologist should be made aware of any serious health problems or previous surgeries. The patient also should tell the technologist of any allergies as they can then determine which contrast dye is the safest for each patient. Patients must always notify the technologists of any possibility of pregnancy.
