Modic type endplate changes

Modic type endplate changes represent a classification for vertebral body end-plate MRI signal, first described in 1988 1. It is widely recognised by radiologists and clinicians and is a useful shorthand for reporting MRIs of the spine.

Recently Modic type I has received renewed attention due to the possibility of it representing low grade indolent infection. It is thus discussed separately here.
