In your wrist or knee, if you are experiencing a problem it typically comes in the form of pain or swelling in that particular area. The results of the scan will be used to identify: The purpose of an MRI is to examine areas of your brain and surrounding bones, muscles, and other soft tissues. Therefore it’s important to accurately identify the area of potential damage to determine a correct diagnosis. Each part of the brain plays a different role in how we function. This allows the radiologist to identify potential abnormalities that could be signs of degenerative diseases such as Alzheimer’s or trauma such as a concussion. The scan works by taking images–called slices–as the MRI moves across three planes:īy taking images across these different planes, the radiologist can build a detailed picture of the important structures in your brain. What does a Head MRI Show?Ī Magnetic Resonance Imaging (MRI) head scan is a non-invasive procedure meant to identify possible trauma or abnormalities. In this guide we will discuss how the procedure is performed, the structures the scan will identify, and how you can prepare for the procedure. However, if you are armed with the knowledge of what to expect, it can make the idea of the procedure much less daunting. There are several scenarios where you might need to have an MRI of your head or brain, including changes in behaviour, pain, or even blurred vision.Īlthough this is a common, routine procedure, the idea of having a diagnostic scan of such an important part of your body can be a little frightening. An MRI scan is a powerful diagnostic tool that can identify trauma or abnormalities in the head and brain. 22 per cent of all MRI scans performed are of the head. Head and brain MRI scans are one of the most commonly scanned parts of the body. MRI Head and Brain Scan: A Definitive Guide of What to Expect
