What's the difference between X-Ray, CT Scan, MRI, and more?

1) X-rays use electromagnetic radiation to produce images of bones and dense structures within the body. They are commonly used to detect fractures, infections, tumors, and other abnormalities. X-rays are fast, relatively affordable, and widely available.

2) CT scans utilize X-rays combined with advanced computer processing to create detailed cross-sectional images of the body. Unlike traditional X-rays, CT scans can capture bones, organs, blood vessels, and soft tissues, making them valuable for diagnosing internal injuries, tumors, infections, and blood clots.

3) MRI employs a powerful magnetic field and radio waves to generate highly detailed images of soft tissues, organs, and internal structures. It offers excellent contrast between different tissue types and is particularly useful for imaging the brain, spinal cord, joints, and muscles. Since MRI does not use ionizing radiation, it is a safer imaging option, especially for pregnant women and children. However, MRI scans take longer, are more expensive, and may not be suitable for individuals with certain medical implants or metal objects in their bodies.

4) A PET scan measures how active different areas of the brain are by detecting how much sugar they consume for energy. The scan highlights areas of high activity in bright colors, as regions using more sugar appear more intensely lit. Since cancer cells consume large amounts of sugar to fuel their rapid, uncontrolled growth, they appear as the brightest areas on a PET scan. This imaging technique is commonly used to detect cancerous cells in the body.

5) MRA (Magnetic Resonance Angiography) scans visualize blood flow within the brain's vascular system. It helps identify vessel narrowing, blockages, or other abnormalities in blood circulation.
