FIG. 1.

TMI⁺ versus TMI^– scans. Example of magnetic resonance imaging obtained from 2 paitents in the study, with and without evidence of TMI. Shown are the GRE which is sensitive to blood, and DWI which is sentitive to ischemia, and pre- and post contrast FLAIR used to detect TMI. Red arrows indicated abnormal enhancment of meningese seen on post-contrast FLAIR in the falx cerebri and along the anterior convexity of the frontal lobe. DWI, diffusion weighted image; FLAIR, fluid-attenuated inversion recovery; GRE, gradient recalled echo; TMI, traumatic meningeal injury.
