Here is the foundation you need to understand how it all works. 1. The Big Four: Common Imaging Modalities Understanding "Density" (The Black and White) Starting a
This uses powerful magnets and radio waves (no radiation!). It is the gold standard for "soft tissues" like the brain, spinal cord, ligaments, and tendons.
