I have found out what my brain scan is about: Magnetic resonance imaging (MRI) What is an MRI? An MRI (magnetic resonance imaging) is a diagnostic scanning tool that can produce images of organs and structures within your body. The MRI scanner uses strong magnetic fields, not X-rays, to create these images. Hydrogen atoms in the patient react to the magnetic fields and a computer analyzes the results to produce a picture. Why would I need an MRI? An MRI is used to check for damage or abnormalities in soft tissue, joints, the brain and the spinal cord. It has some advantages over a computed tomographic imaging (CAT) scan. MRIs provide better contrast, which helps to distinguish between normal and diseased tissue, and MRIs do not show confusing bone artifacts. An MRI provides highly detailed information without exposing the body to radiation. In many instances, it provides more useful images than CAT scanning and ultrasound. How is an MRI performed? You lie on a table that slides into a tunnel in the scanner. The table will then be moved so that the area of your body to be viewed is in the center of the machine's "tube." The tube remains open on one end so that you are not completely closed in. You begin hearing a series of loud knocking sounds. Remain still while the pictures are being taken. The MRI should take about half an hour. Results are usually available in a few hours. An MRI is non-invasive and does not hurt. You may become uncomfortable or claustrophobic, but you should feel no pain. You can communicate with the MRI technician. Let that person know if you are uncomfortable. If you are anxious about confined spaces, ask about an open MRI. How should I prepare for an MRI? Don't eat or drink six hours before the exam. At the examination room, you should remove buttons, zippers and any other metal objects. Seriously I really hope i'm fine. =*( written by*-- Zhiwang
