Question

Quizplus · Accepted Answer

MRI scans generally provide more detailed structural information than CT scans. They use radio waves and magnets to create images of internal organs and tissues. While CT scans use X-rays to produce images, which can expose patients to ionizing radiation and pose greater risks. MRI scans are also better at visualizing soft tissues and organs, making them ideal for imaging the brain, spinal cord, and joints. However, CT scans may be preferred for emergency situations, such as detecting internal bleeding after a trauma, as they are quicker and more widely available. MRI scans are also less informative about blood flow and oxygen flow in the body, but can still provide some functional information. They are not typically used for measuring electrical activity.
