How MRI Uses Magnetism
MRI uses strong magnets to align hydrogen atoms. Radio waves then disturb this alignment. The returning signal forms an image.
Why MRI Shows Soft Tissue Well
MRI shows soft tissue well because it detects water content. This makes muscles, organs, and ligaments clearer. Soft tissue contrast is excellent.
Common Uses for MRI
Common uses for MRI include brain, spine, and joint imaging. It also helps detect soft tissue injuries. MRI is ideal for detailed evaluation.
Limitations of MRI
Limitations of MRI include long scan times. It also cannot be used with some implants. Safety screening is essential.
