For a comprehensive spinal MRI interpretation, which tissues are central to assessing soft tissue involvement?

• A. Facet joints and ligaments
• B. Disc, cord, soft tissue
• C. Vertebral bodies and bone marrow
• D. Nerve roots and blood vessels

Answer: (C)

In spinal MRI interpretation, bone and bone marrow signals provide essential clues about soft tissue involvement. Pathology that affects soft tissues around the spine often starts in or is best characterized by changes in the vertebral bodies and their marrow. Marrow edema, tumor, infection, or fracture can extend into adjacent soft tissues such as the epidural space, paraspinal muscles, ligaments, and discs. By identifying marrow abnormalities first, you establish the likely extent and boundaries of soft tissue involvement and then assess how those changes correlate with the surrounding structures on the MRI sequences that best highlight soft tissue contrast (like fat-suppressed T2/STIR and post-contrast T1 with fat suppression). While ligaments, facet joints, discs, and neural elements are important components to evaluate, the marrow signal often anchors the overall assessment of where soft tissue involvement is present and how far it may spread.
