Will my head be out of the MRI for an tibia?

Your head will not be inside the MRI machine for a tibia scan. The MRI machine is a large, cylindrical magnet that creates a strong magnetic field. During an MRI scan, the patient lies on a table that moves into the magnet. The part of the body being scanned is positioned within the magnetic field. For a tibia scan, your lower leg will be positioned within the magnetic field, while your head will remain outside of the machine.
