FAQs about 1.5T MRI Brain Functional Scan (fMRI) in Chandigarh CHD
What is a 1.5T MRI Brain Functional Scan (fMRI)?
A 1.5T MRI Brain Functional Scan, also known as functional MRI or fMRI, is a specialized imaging technique used to measure and map brain activity by detecting changes in blood flow. It is particularly useful in assessing brain function, identifying areas responsible for certain cognitive tasks, and is widely applied in research, surgery planning, and diagnosis of brain disorders.
How long does an fMRI scan take?
An fMRI scan typically lasts between 30 minutes to 1 hour, depending on the complexity of the study and the number of sequences being performed. During this time, patients are required to lie still while the machine takes images of the brain. It's important to follow the instructions provided by the technician to ensure optimal results.
Is the fMRI scan safe?
Yes, the 1.5T MRI Brain Functional Scan is considered safe. It does not use ionizing radiation; instead, it utilizes a strong magnetic field and radio waves to create images. However, individuals with certain implants, metallic devices, or claustrophobia may need to consult with their doctor prior to undergoing the scan.
What should I expect during the fMRI procedure?
During the fMRI scan, you will be asked to lie down comfortably in the MRI machine. You may be provided with earplugs or headphones to dampen the loud noises produced by the machine. Depending on the purpose of the scan, you might be instructed to perform specific mental tasks, but no pain or discomfort is associated with the procedure.
How can I prepare for an fMRI scan?
Preparation for an fMRI scan usually includes wearing comfortable, non-metallic clothing and removing any metal objects like jewelry, watches, or hairpins. It's advisable to inform your healthcare provider about any medications, health concerns, or previous reactions to MRI scans.
