Which tissue categories are routinely considered in interpreting an MRI scan of the spine?

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

Answer: (C)

The key idea is recognizing how spine MRI is organized around major tissue compartments, with the vertebral bodies and their bone marrow forming the fundamental category you routinely assess. Bone marrow signal is highly sensitive to a wide range of pathology—edema from acute fractures, osteomyelitis, marrow infiltration from tumors, or marrow-replacing processes—and the vertebral bodies themselves provide essential landmarks for alignment, height, and relationships to the discs and spinal canal. While discs, the spinal cord and nerve roots, ligaments, and other soft tissues are all important to evaluate, they are typically interpreted in the context of this bone/ marrow framework. Other structures like facet joints or vessels are considered as part of the broader assessment, but the vertebral bodies and bone marrow remain the primary tissue category you routinely examine.
