Radiographic/MR Imaging Correlation of Paravertebral Ossifications in Ligaments and Bony Vertebral Outgrowths: Anatomy, Early Detection, and Clinical Impact.

This article focuses on the variety of imaging features of paravertebral ossifications that are of practical interest in the diagnosis of diseases. The spinal anatomy is reviewed and correlated to paravertebral ligamentous ossifications and their potential clinical impact. A vertebral bony outgrowth is secondary to inflammation or degeneration and can be characterized based on its origin and growth direction, in addition to appreciation of intervertebral disc space preservation or loss. Imaging in rheumatology patients is highlighted because early detection of disease is of increasing importance. A correlation between radiographs and MR imaging is made.
