FAQs about 3T MRI Brain Functional Scan (fMRI) in Chandigarh CHD
What is a 3T MRI Brain Functional Scan (fMRI)?
A 3T MRI Brain Functional Scan, also known as functional MRI (fMRI), is an advanced imaging technique that measures and maps the brain's activity. It does this by detecting changes in blood flow and oxygen levels, allowing medical professionals to identify regions of the brain that are activated during cognitive tasks. This non-invasive procedure can help diagnose conditions like brain tumors, stroke, and various neurological disorders.
How should I prepare for a 3T MRI Brain Functional Scan?
Preparation for a 3T MRI Brain Functional Scan usually involves a few steps. First, inform your doctor about any medications you're taking and discuss any allergies. Patients are typically advised to wear loose-fitting clothing without metal zippers, buttons, or jewelry, as these can interfere with the MRI process. Additionally, you may be asked to refrain from eating a few hours before the scan to minimize discomfort. It's important to follow any specific instructions provided by your healthcare provider or the imaging center.
Is the 3T MRI Brain Functional Scan safe?
Yes, the 3T MRI Brain Functional Scan is considered safe for most patients. It uses strong magnetic fields and radio waves rather than ionizing radiation, making it less risky compared to other imaging techniques. However, patients with certain implanted medical devices, such as pacemakers or cochlear implants, should discuss their medical history with their doctor prior to the scan, as these devices could pose a risk in the MRI machine.
How long does a 3T MRI Brain Functional Scan take?
The duration of a 3T MRI Brain Functional Scan can vary but generally takes about 30 to 60 minutes. The actual scanning time may depend on the specific brain functions being assessed, as well as the instructions given during the assessment. During this time, patients will lie still in the MRI machine while images are being captured, and it is essential to remain as still as possible to ensure clear images.
What happens after a 3T MRI Brain Functional Scan?
After the 3T MRI Brain Functional Scan, patients can typically resume their normal activities immediately. There are no side effects from the scan itself, and any feelings of claustrophobia or discomfort should subside once the procedure is completed. A radiologist will analyze the images and provide a report to the referring physician, who will discuss the findings and any necessary follow-up actions with the patient.
