During the scan, your child will be asked to do certain things, such as answering questions or tapping one finger. The radiographer will warn your child when a loud noise is due by talking to him or her through an intercom. It has an advantage over other imaging studies that focus only on the structure of the brain. It detects the brain in action (e.g., speaking or moving). Functional MRI is a noninvasive diagnostic test that measures small changes in blood flow as a person performs tasks while in the MRI scanner. The scanner will make a continuous knocking sound throughout the scan, which can be quite loud, but we will give your child ear protectors to minimise any discomfort. Brain mapping: functional MRI and DTI Overview. When your child is in the correct position, the radiographer will move the bed inside the scanner and then go into the control room. Your child will need to lie on the bed for the scan. If your daughter is 12 years old or older, we will ask her about her periods and any possibility she could be pregnant. You are welcome to stay with your child during the scan, but if you are in the first three months of pregnancy, you should let us know before the scan. When you arrive at the hospital, you should report to the MRI department. Your child will need to keep his or her head very still for the scan, so we may use some sandbags to help. You will also need to leave metallic objects like jewellery, watches, keys, pens or cards with metallic strips like bank cards and train tickets in the lockers outside the scanner room. We will ask you to sign a form to confirm this. Your child should wear clothes without zips or metal poppers for the scan, otherwise he or she will need to change into a gown.īefore the scan starts, the nurse or radiographer will check you or your child do not have a pacemaker, metal implants or clips, dental braces, a history of metal fragments in the eyes or any allergies. The scanner does not touch your child during the scan.Īll types of MRI scan are unsuitable for people with any metal inside them (pacemakers, surgical clips or metallic implants) because the scanner emits a strong magnetic field. They are painless and generally quick with no lasting effects. There are no risks associated with fMRI scans. Since its inception in 1991, blood oxygen level-dependent (BOLD) fMRI has rapidly become a vital methodology in basic and applied neuroscience research. Functional MRI will only detect brain activation very indirectly, as variations in. Functional magnetic resonance imaging (fMRI) maps the spatiotemporal distribution of neural activity in the brain under varying cognitive conditions.

#FUNCTIONAL MRI SOFTWARE#
This is accomplished through publications, training courses, and by making software and databases available. The technologies being developed are disseminated to investigators nationwide and throughout the world. This technology development is done in collaboration with a large community of clinicians and neuroscientists at several institutions in Maryland and throughout the USA. Our resource is dedicated to the design of quantitative magnetic resonance (MR) acquisition and processing technology to assess tissue changes and alterations in function, metabolism, and physiology as the brain changes during neurodevelopment or neurodegeneration. Functional MRI (fMRI) is now also well established in many centers and uses similar imaging techniques and the same equipment as conventional MRI. Welcome to the National Research Resource
