Magnetic resonance imaging (MRI) is particularly effective at visualizing soft tissues because it relies on the detection of hydrogen atoms, which are abundant in the body's water and lipids.12

Because MRI produces excellent images of intracranial and intraspinal contents, it is especially valuable for imaging the following structures:

  • Central Nervous System: The brain and spinal cord.12
  • Organs: The heart, liver, kidneys, spleen, pancreas, breast, and pelvic organs, such as the urinary bladder.12
  • Musculoskeletal System: Cancellous (spongy) bone, as well as cartilage and ligaments within joints.1
  • Vascular System: Through a specialized technique called magnetic resonance angiography, it can visualize arteries and veins to produce images of flowing blood.1

While MRI is highly sensitive in differentiating between normal and diseased tissues—such as identifying tumours or neural plaques—it is less effective at imaging dense bone, which typically appears black in scans.12
