RMN Cerebral is the most accurate imaging test available for brain and spinal cord disorders. It works by exciting tissue hydrogen protons to emit electromagnetic signals that are interpreted by the scanner and translated into gray-scale images of your brain. MRI can detect the presence of blood vessels, nerves, tumors, and other abnormalities.
It is important to remain as still as possible during the imaging sequences, which last a few seconds or minutes at a time. To help reduce the discomfort and distraction, many facilities have earplugs and headphones available for you to wear during your scan. Some MRI scanners also play music to help pass the time between sequences.
Exploring the Depths: The Importance of Cerebral MRI in Neuroimaging
You will need to remove any jewelry, piercings, or other metal objects before entering the MRI scanner. These objects can interfere with the ability to create clear images and may even cause injury if they come into contact with the magnetic field. The healthcare team will ask you to wear a hospital gown and store your clothing in a locker until after the scan. The radiologist will need to know your medical history and whether you are pregnant, as the strong magnetic force of the MRI scanner can affect unborn babies in a way that isn’t understood.
In some cases, a contrast dye may be used to help a radiologist better see certain structures in the brain. The contrast dye is typically administered via a vein in your arm. The radiologist will need to know if you have any implanted devices (like pacemakers or shunts for hydrocephalus) as they can affect the way the contrast dye moves through your body and into the brain.
