Yale Medicine is able to offer MRI scans for many people with these devices implanted in their bodies in situations where most others hospitals can't do them. Patients with some modern versions of cardiac pacemakers and defibrillators can safely undergo an MRI, but most people have older devices, which aren’t FDA-approved for use in an MRI scanner. Surgical clips, including aneurysm clips.Medical devices with magnets, such as a cochlear implant or chest expanders.Body piercings, jewelry, metal on or in clothing.Pins or plates in or on your bones, including metallic joint.Embedded bullets, BB's, shrapnel, shotgun pellets or metal filings.Braces on your teeth, a retainer or dental fillings.Patients with medical implants or other metal in or on their bodies are often unable to undergo the exam in most hospitals Yale Medicine physicians have developed strategies that often solve this problem. In this article, we examine the issues that might exist in a variety of scenarios-and how Yale Medicine physicians deal with them. Not only is the machine noisy and confining, but it does not interact well with some metals in the body. However, the prospect of getting an MRI scan causes anxiety for some patients.
Rather than using radiation, as X-rays do, the MRI machine uses magnetic fields and radio waves to generate images.This makes it safer, overall. The magnetic resonance imaging (MRI) machine is frequently used to help diagnose a wide range of diseases and medical conditions, ranging from cancer and heart disease to disorders of the bones and joints. “An MRI allows you to see internal anatomy in detail, and also to differentiate between normal and abnormal tissues,” says Jeffrey Weinreb, MD, chief of the MRI service at Yale Medicine.
