Updates to Article Attributes
Modic type endplate changes represent a classification for vertebral body endplate MRI signal changes, 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: low signal
T2: high signal
T1 C+ (Gd): enhancement
-
Modic type II:
T1:high signal-
T2:iso to high signal - represents normal red haemopoietic bone marrow conversioninto yellow fatty marrowas a result of marrow ischaemia
T1: high signal
T2: iso to high signal
-
Modic type III:
T1:low signal-
T2:low signal - representssubchondral bony sclerosis
T1: low signal
T2: low signal
