Imagine two powerful, non-invasive imaging tools, each with its own unique set of capabilities. Both MRI (Magnetic Resonance Imaging) and CT (Computed Tomography) scans are essential in the medical field for diagnosing and treating a wide range of conditions. Yet, they operate on entirely different principles and are used in distinct scenarios. Understanding the differences between MRI and CT scans can empower patients to make informed decisions about their healthcare. This article will delve into the workings of MRI and CT scans, their benefits and drawbacks, and why a healthcare professional might choose one over the other.

How MRI and CT Scans Work

MRI St George uses a strong magnetic field and radio waves to create detailed images of the body's soft tissues, including the brain, spine, joints, and organs. The magnetic field aligns the water molecules in your body, and as they return to their natural state, they emit energy that is detected and converted into detailed images by a computer. MRI is excellent at visualizing internal structures and can differentiate between various types of tissue. On the other hand, CT scans rely on X-rays to produce cross-sectional images of the body. The X-ray beam moves around the patient, capturing images from multiple angles. These images are then reconstructed by a computer into a detailed, 3D picture of the internal body structures. CT scans are particularly adept at capturing images of bones, blood vessels, and organs. (more…)
