The MRI exam is a safe and painless procedure that uses a magnetic field and radio waves to produce highly detailed images of the inside of areas within the body. Superior images of the brain and spine can be produced. In addition, the cartilage and ligaments of many joints, such as the knee, ankle, shoulder, elbow and jaw, can be seen with clarity. With 3-D magnetic resonance angiography (MRA), noninvasive imaging of blood vessels in the neck, chest, abdomen and legs can be performed. And here at Baton Rouge Radiology Group, we are certified in MRI by the American College of Radiology.
