Which imaging modality best evaluates soft tissues such as ligaments around the spine?

• A. CT
• B. MRI
• C. X-ray
• D. Nuclear medicine

Answer: (B)

When evaluating soft tissues around the spine, you want imaging with high soft-tissue contrast to distinguish ligaments from surrounding structures. MRI uses magnetic properties of tissues to create detailed images and offers multiple sequences that highlight ligaments, discs, and surrounding soft tissue, making tears or inflammation easy to see. CT provides excellent detail of bone but relatively limited soft-tissue contrast, so ligaments aren’t as clearly delineated. X-ray mainly shows bone alignment and degenerative changes with little soft-tissue information, and nuclear medicine focuses on function rather than detailed anatomy. Therefore, MRI is the best choice for assessing ligaments around the spine.
