Modic type endplate changes

Dr Craig Hacking and Radswiki et al.

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.

  • Modic type I
    • T1: low signal
    • T2: high signal
    • represents bone marrow oedema and inflammation
    • T1+C: enhancement
  • Modic type II
    • T1: high signal
    • T2: iso to high signal
    • represents normal red haemopoietic bone marrow conversion into yellow fatty marrow as a result of marrow ischaemia
  • Modic type III
    • T1: low signal
    • T2: low signal
    • represents subchondral bony sclerosis
