Comparison of MRI scans across different time-points after exposition. 30 and 45 days after initial event, FLAIR sequences show a diffuse and confluent hyperintensity involving predominantly the periventricular and deep white matter. Follow-up MRI scans (60, 150, 180, and 540 days after initial event) show gradual regression of the FLAIR hyperintensity.

T2 and Fluid Attenuated Inversion Recovery (FLAIR) sequences (Figure 2). The hematologic, biochemical, and serological studies as well as HbCO levels were unremarkable. The results of this processing pipeline are presented in Figure 2.
