What is magnetic resonance imaging Magnetic resonance imaging (MRI) is a test that uses a magnetic field, the energy pulses of radio waves and a computer system to provide images of organs and structures within the body. In many cases, an MRI provides information that can not be obtained from an X-ray, ultrasound or CT scan.
For an MRI test, the area of the body under study is placed within a strong magnetic field. Magnetic resonance imaging can detect changes in the normal structure and characteristics of organs or other tissues. These changes may indicate illness caused by trauma, infection, inflammation or tumors. Information from a magnetic resonance imaging is saved and stored on a computer for further study by a doctor.
In some cases, a contrast medium can be used during MRI scanning to enhance images of some structures. The contrast material can help to evaluate blood flow, detect certain types of tumors, and locate areas of inflammation.
What to Expect
You will be asked to lie down on the MRI table. Depending on the exam, it can be positioned head-first or feet-first and examination usually take between 30 and 60 minutes. The table is moved to the position within the large donut-shaped magnet. The body part that is taken must be positioned at the center of the magnet. The technician will be in contact with you at all times visually and through headphones. You will hear a series of repetitive pulses or knocking noises. The noise occurs when the pictures were taken so it is particularly important to keep very still. Movement causes the image to blur and you can lengthen the time of examination as it would be necessary to repeat that sequence. Music with headphones or earplugs are offered to muffle loud noises heard during the exam.
Your doctor or radiologist will determine if you need an injection of contrast (dye) to complete the test. The contrast material can help to evaluate blood flow, detect certain types of tumors, and locate areas of inflammation. This contrast does not contain iodine.
dietary restrictions
If you are scheduled for an examination of your bile ducts or liver problems, please do not eat or drink anything for 4-6 hours before your exam.
