RMN Cerebral of the brain produces high quality two-dimensional or three-dimensional images of the brain and its structures without the use of ionizing radiation (X-rays). It is an excellent diagnostic test for conditions such as cerebrovascular disease, dementia, Alzheimer’s, Parkinson’s, multiple sclerosis, epilepsy and some cancers. It can also detect small blood vessels in the brain.
A very strong magnetic field and radio wave signals are used to generate the MRI scans. This can cause heating or movement of some implanted medical devices in the body. It is therefore important to tell the staff if you have any metal objects in your body, such as dental work, jewellery, hairpins, removable dental fillings or pacemakers. If these are present, your doctor may need to schedule a different exam or give you other preparation instructions.
The Brain Unveiled: Exploring the Purpose and Process of Cerebral MRI
If you are given a contrast material to improve the quality of the MRI images, it will be injected through an intravenous line into a vein in your hand or arm. This is most often gadolinium, which is a rare earth metal that changes the magnetic properties of water molecules in your body and enhances the accuracy of the diagnostic images. It is generally well tolerated and does not cause any allergic reactions.
The MRI procedure is painless and poses no risk to you when the safety guidelines are followed. You will be asked to lie down and remain very still during the entire scan. Earplugs can be provided to help mask the noise and music is sometimes played to assist with relaxation.
