Magnetic Resonance Imaging (MRI) uses radiowaves and a strong magnetic field rather than xrays to produce detailed images of body tissues and organs. The magnetic field “excites” and then “relaxes” protons in the body, emitting radio signals. The radio signals are processed by a computer to form an image. Usually the entire process will take an average of 45 minutes to 1 hour, allowing time also for paperwork and patient care. The exam time may vary from exam to exam. If you are having multiple exams allow extra time for each region being scanned. For questions about your MRI, or to schedule an appointment, please call 402-269-7590.
Preparing for your MRI
Clothing should be free of metal. The technologist will ask whether you have a pacemaker, brain aneurysm clips, artificial limbs, or any metal screws or plates. A patient with a pacemaker cannot have an MRI. In most cases, metal used in orthopedic surgery pose no risk during an MRI. You will also be asked if you have ever had a bullet or shrapnel in your body or ever worked with metal. If there is a possibility of metal shrapnel in the eyes, you will be asked to do an x-ray prior to the MRI.
