thumb_111

 

Magnetic Resonance Imaging (MRI) is a common exam used to evaluate many disease processes and musculoskeletal injuries.  MRI images are obtained using a combination of radio waves and magnetic fields. Special coils are placed which act like antennas to pick up signal in the area being scanned. The MRI patient must remain still and will be given instructions by the technologist throughout the examination. The MRI units can be noisy so earphones for music or ear plugs are often used.  Sometimes an injection of mri dye is needed to help the exam.

The MRI evaluation of blood vessels is an exam is referred to as magnetic resonance angiography or MRA.

Other MRI exams include Breast MRI used for breast cancer detection and diagnosis as well as screening high risk patients.
