Inside Medical Imaging: MRI And CT Scan Differences Explained
What MRI And CT Scans Are Used For: MRI and CT scans are two common medical imaging tests doctors use to look inside the body. Both help diagnose injuries, diseases, and other health problems, but they work in different ways and are used for different reasons. A CT scan, also called a computed tomography scan, uses X-rays to create detailed pictures of the body. It is often used in emergency situations because it works quickly. Doctors may order a CT scan to check for broken bones, internal bleeding, strokes, lung problems, or tumors. An MRI, which stands for magnetic resonance imaging, uses powerful magnets and radio waves instead of radiation. MRI scans are especially useful for looking at soft tissues like muscles, ligaments, the brain, spinal cord, and organs.
