How does MRI compare to CT?
Advantage of MRI over CT better soft tissue imaging multiple imaging planes available no X-ray needed less IV contrast needed IV contrast is safer Disadvantage of MRI over CT somewhat slower slightly more expensive Q: For what types of medical problems is MRI the most useful? A: MRI is best at seeing soft tissue. Therefore, it is very useful for brain and nervous disorders (stroke, traumatic injuries, fluid in the skull, tumors, multiple sclerosis, and spinal conditions or diseases). It is also beneficial for musculoskeletal problems (ligament, tendon and cartilage injuries) and subtle bone injuries and tumors. Newer applications include imaging of the abdominal and pelvic organs (liver, kidneys, pancreas, uterus and ovaries). MR can also evaluate the heart and blood vessels. Q: How does an MRI work? A: The body is made up of tiny particles called atoms. Protons located inside the atoms continually spin at random. The magnetic field from the MRI’s magnet makes the protons line up toget
