Initial (A-B) and follow-up (C-D) sagittal magnetic resonance images of one patient. Type I Modic changes (arrows; high signal on T2-weigthed image A, low signal on T1-weighted image B) alters to type II (high signal on T2- and T1-weighted images C and D; images not shown revealed alteration to type II/I).Back to article page
