An average MRI exam takes approximately 30 minutes to complete, depending on what type of exam is being performed. During the exam, an injection of contrast may be necessary to improve image quality and provide more information. This substance (gadolinium) contains no iodine, and side effects are rare.
MRI images are obtained using a strong magnetic field; therefore careful screening must be done to limit metal objects into the exam room. A questionnaire must be filled and signed prior to any MRI exam to verify for any metal implants, objects or devices for your safety.
