Frequently Asked Questions
What is a 7 Tesla MRI?
A 7 Tesla MRI is a type of magnetic resonance imaging (MRI) that uses a much stronger magnetic field than standard MRI machines (typically 1.5 or 3 Tesla). This stronger field allows for significantly higher resolution images, meaning we can see smaller details within the body with greater clarity. 7 Tesla MRI is considered a high-field MRI and is often used in research settings and specialized clinical applications.
How does a 7 Tesla MRI work?
Like all MRI machines, a 7 Tesla MRI uses a powerful magnet to align the protons in our bodies. Radio waves are then emitted, causing these protons to temporarily shift their alignment. When the radio waves are turned off, the protons realign with the magnet, emitting a signal that is detected by the machine. This signal is processed to create detailed images of the internal structures.
Why should I choose a 7 Tesla MRI?
A 7 Tesla MRI offers several advantages over standard MRI machines. The higher resolution images allow for earlier and more accurate diagnosis of certain conditions, particularly in areas like the brain, spine, and muscles. It can also help guide biopsies and other minimally invasive procedures with greater precision. However, it’s important to note that 7 Tesla MRI is not always necessary and your doctor will determine the best imaging option for your specific needs.
How do I know if I need a 7 Tesla MRI?
Your doctor will recommend the appropriate type of MRI based on your symptoms, medical history, and the specific area of the body that needs to be examined.
