When a you look at an MRI scanner , you notice a machine with a tunnel in the middle. MRI scanners magnetic field strengths vary from 0.2 to 1.5 tesla. Higher field strength (tesla) equals systems that are able to align a larger quantity of hydrogen protons. This allows for increased image quality and speed. The magnetic field is needed to move and align the hydrogen protons. Once the magnetic field aligns the hydrogen protons, radio frequencies are pulsed at your body. This radio frequency pushes the proton out of alignment. As these protons wobble back into alignment they create a radio signal of their own. This signal is received by the coil or antenna that is placed in the area we are scanning. MRI is safe in most cases, and there are no documented side effects. Despite this pregnant women are usually advised to avoid an MRI scan. A questionnaire will be filled out by you and a careful screening for metal is conducted by our technologists, in order to prevent any injury. Different metals are used for surgery and there are a few cases when MRI cannot be attempted: Cardiac pacemakers. Cerebral aneurysm clip. Magnetically activated or supported implants. Implanted electromagnetic devices. Metallic fragments in eyes.

A MRI scanner can, in a rudimentary sense, be thought of as a gigantic magnet approximately 600 times stronger than a refrigerator magnet. Generally, MRI scanners produce magnetic fields between 1.5 T and 3 T. The MRI scanner (Figure 1) applies high strength magnetic fields, often in order to image the brain. The brain is composed of approximately 70% water, which comprises hydrogen and oxygen atoms. The nuclei of hydrogen atoms have nuclear spins, and will take on a high-energy or low-energy state, depending on whether the nuclei orient against or align with the magnetic field, respectively. When the nuclei undergo changes between the two states, they absorb or emit energy in the radiofrequency range, which is subsequently detected by the MRI scanner. The high field MRI machine first exposes the brain to a powerful magnetic field that causes the hydrogen protons in those water molecules to line up. Then it uses electromagnetic waves to knock the protons out of alignment. Finally, it stops the waves and measures the time it takes for the protons to relax back into line. Data collected about the relaxation time at each brain location (or pixel) are then translated into a high-resolution image of living neural tissue. An MRI machine is a very useful diagnostic medical instrument, but there are some problems with its' usage. For example, people who are obese or claustrophobic can not have an MRI scan done because it is too small and enclosed.
