FAQs about MRI Brain Functional Scan (fMRI) in Chandigarh CHD
What is a functional MRI (fMRI) scan?
A functional MRI (fMRI) scan is a specialized imaging technique used to measure and map brain activity by detecting changes in blood flow. Unlike a traditional MRI which provides static images of the brain's structure, fMRI is dynamic and can represent brain functions in real time. It is particularly useful for neurosurgeons and psychologists as it helps understand how specific areas of the brain are activated during certain tasks or responses.
How should I prepare for an fMRI scan?
Preparation for an fMRI scan involves several key steps. First, it is essential to inform your healthcare provider of any medical implants or devices, as some may be incompatible with the MRI machine. Please wear comfortable, loose-fitting clothes and avoid any metal accessories such as jewelry or hairpins. You may be asked to refrain from eating or drinking several hours prior to the scan to minimize discomfort during the procedure. Lastly, ensure to arrive at the imaging center with ample time for any necessary paperwork and preliminary assessments.
How long does an fMRI scan take?
An fMRI scan typically takes between 30 minutes to an hour, depending on the specific protocols used and the complexity of the study. During the scan, you may be asked to perform certain tasks, such as thinking about specific concepts or engaging in simple exercises, to help capture brain activity accurately. Your comfort and safety are our top priorities, and we'll ensure that your experience is as efficient and stress-free as possible.
Is fMRI safe?
Yes, functional MRI (fMRI) is considered a safe procedure without the use of ionizing radiation, making it non-invasive. However, it is important to disclose any medical conditions or implants that you might have to ensure your safety during the scan. Our trained technicians will monitor you throughout the process, and we take all necessary precautions to mitigate any risks associated with the fMRI.
What conditions can be diagnosed with an fMRI scan?
An fMRI scan can aid in the diagnosis and management of various neurological conditions, including epilepsy, brain tumors, strokes, traumatic brain injuries, and neurodegenerative disorders such as Alzheimer's disease. It is also frequently used in pre-surgical planning for brain surgeries, as it helps identify the crucial functional areas of the brain that should be preserved during the procedure.
