Cerebral MRI uses powerful magnets to create images of brain structures. Unlike x-ray and computed tomography (CT) scans, MRI does not use radiation. Instead, radio waves re-align hydrogen atoms that naturally exist in body tissues. When these atoms are stimulated, they release energy which the scanner detects. Different tissues respond in different ways to this energy, and the scanner produces pictures based on these differences.Go here :biomedscan.ro
During the MRI scan, you will lie down on a table that slides into a large magnet shaped like a tube. A coil may be placed around your head to improve image quality. MRI is a painless procedure. You will hear repetitive tapping and thumping sounds from the internal part of the magnet, but you can ask for music to play during the scan to help reduce this noise. Some MRI exams require the injection of dye, typically gadolinium. This enhances the sensitivity of diagnostic images and improves the detection of certain conditions, such as multiple sclerosis, stroke, dementia, and infection. The contrast material is administered through an intravenous line (IV) inserted into a vein in your hand or arm. Gadolinium can cause allergic reactions in some people.
Inside Out: Exploring the Insights of Cerebral MRI for Brain Imaging
The MRI scans will be reviewed by two trained neuroradiologists. We will call you if any incidental findings need to be discussed with you. You should bring a list of any medications you are taking to your appointment, as well as any past medical history and recent test results.
