Which imaging modality uses magnetic fields and radio waves to produce detailed images of soft tissues?

• A. CT scan
• B. Magnetic resonance imaging
• C. Radiography
• D. Ultrasound

Answer: (B)

Magnetic resonance imaging uses strong magnetic fields and radiofrequency energy to excite hydrogen protons in the body's tissues. As these protons relax, they emit signals that are converted into highly detailed images, providing superb contrast for soft tissues such as ligaments, tendons, cartilage, muscles, nerves, and edema. This depth of soft-tissue detail, without exposing you to ionizing radiation, makes MRI the best choice for evaluating foot and ankle soft tissue injuries, plantar fascia issues, tendon/pathology, and occult marrow changes. Other modalities rely on ionizing X-rays or ultrasound waves and don’t offer the same soft-tissue contrast and clarity, so they don’t fit this description.
