Magnetic resonance imaging (MRI) is a modern technique that produces images of the inside of the abdomen without any exposure to ionizing radiation. An MRI test is done with the help of radio waves and powerful magnets. Both of these work together to produce images on the computer that help doctors detect abnormalities, if any, in the tissues and the structure of organs. MRI makes use of radio waves, the frequency of which is in the range of FM Radio frequencies.
Why is it done? An abdominal MRI test is conducted in order to diagnose for any cancerous growth in the abdomen. It is also used to diagnose and evaluate blood flow, check for a stone or blockage in the bile duct, or check the pelvic organs as well as abdominal organs for any possible congenital problems.
How is the test performed?
It usually takes an hour for the test to complete. You will have to lie down on a table which will slide into a large tunnel that is located within the scanner. Just before the test some dye might be injected inside your veins in order to produce better and clearer images. Before taking an MRI test you will need to prepare yourself for the test.
You have to get your colon cleared, before the test, either by taking a laxative or an enema. You will also not be allowed to consume any food and water for sometime before the scan. You are required to wear a gown during the test, which will be provided by the hospital. You should not take any metallic objects like jewellery, watches, or pins into the scan room, which might either be damaged or might cause errors in the images produced by the scan. Most important of all, if you have any artificial metallic objects inside your body, like a pacemaker or artificial heart valves, you should never go for an MRI.
What are the side effect?
The test itself is painless. You will not feel the radio waves or magnetic field. If you find it difficult to lay still and become anxious, you might be given a mild sedative. During the entire test procedure, you will be in complete control of your senses and will be able to speak with the operating person, if needed, through the attached intercom. As for the risks, there are no known cases of any significant side-effects. Also, there have rarely been any allergic reactions to the dye used. The person operating on the machine will monitor your heart rate and breathing, throughout the process.
