During spinal MRI analysis, which structures constitute the primary soft tissue elements of interest?

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

Answer: (D)

The main idea is recognizing the soft tissue structures that form the supportive envelope of a motion segment and that drive stability and space within the spine. The facet joints and the surrounding ligaments are this soft tissue framework. The facet joints (zygapophyseal joints) and the ligaments—like the anterior and posterior longitudinal ligaments, ligamentum flavum, and the interspinous/supraspinous ligaments—are the key tissues MRI evaluates to assess stability, degenerative changes, and potential canal or foraminal compromise. They often show changes such as facet arthropathy, ligament thickening, or ligament tears, which can directly affect symptoms. Other structures listed are either bone (vertebral bodies) or neural contents (nerve roots, spinal cord) or disc tissue; while important, they’re not the primary soft tissue elements used to describe the spine’s soft tissue envelope and stability in this context.
