MRI vs X-rays
Can you tell me what structures of the knee would show up on an MRI and what ones will show up on an X-Ray?
A simplified answer is that "X-rays reveal bone", whereas MRI scans also depict bone (some features of which are actually better seen with X-rays), but are particularly useful to visualize such "soft tissues" as:
· cartilage (e.g., articular, meniscal, labral, disc)
· blood vessels
· nerve (e.g., peripheral nerves, brain, spinal cord)
· organs (e.g., liver, heart, etc.)
· lymph nodes
· scar tissue (may require contrast), and
· soft tissue tumors.
