I just had my first MRI, it was truly a new experience which I found fascinating. I was expecting it to be fast and quite, but I was wrong in both counts. It sounded like an old out-of-tuned church organ, only playing one note for a solid two minutes. Laying in one position for thirty minutes wasn't an easy feat for this hyperactive person. I haven't receive the results yet, but I will never forget the adventure.
Magnetic resonance imaging (MRI) is primarily used in medical imaging to visualize the structure and function of the body. It provides detailed images of the body in any plane. MR has much greater soft tissue contrast than computed tomography (CT) making it especially useful in neurological, musculoskeletal, cardiovascular, and oncological imaging. Unlike CT it uses no ionizing radiation, but uses a powerful magnetic field to align the magnetization of hydrogen atoms in the body. Radio waves are used to systematically alter the alignment of this magnetization, causing the hydrogen atoms to ...
