Introduction to MRI

Magnetic Resonance Imaging (MRI) is a non-invasive way to view organs, tissues, bones, and other structures inside the body. It uses strong magnetic fields and radio waves to produce internal images of the body. Unlike X-ray and CT scans, MRI machines produce cross sectional, 3D images of the body without using the use of radiation. Doctors often use MRI to view parts of the body that are hard to see with other imaging techniques such as x-rays, ultrasound, or computed tomography (CT) scans. MR imaging is used to diagnose many different types of diseases including heart and vascular disease, stroke, muscle and skeletal (bone) disorders and cancer.^{(1) (2)}
