# Are You Getting the Right Test? CT Scan or MRI? When your doctor recommends imaging tests like CT scans and MRI scans, the question often arises: Are you getting the right test? Understanding the differences between CT (Computed Tomography) and MRI (Magnetic Resonance Imaging) can help you make informed decisions about your health and ensure you receive the most accurate diagnosis tailored to your condition. ## What Is a CT Scan and How Does It Work? A CT scan uses X-rays combined with computer processing to create detailed cross-sectional images of the body. It is fast, widely available, and excellent for visualizing bones, detecting bleeding, identifying cancers, and guiding procedures. Since it uses ionizing radiation, CT scans should be used judiciously, especially during pregnancy or when repeated imaging is required.
