1 T1-weighted image obtained 2 months after exposure to carbon monoxide (A) shows slightly high-signal-intensity lesions in the bilateral substantia nigra. T1-weighted image obtained 2 months after exposure to carbon monoxide (A) shows slightly high-signal-intensity lesions in the bilateral substantia nigra. T2-weighted image (B) shows confluent high-signal-intensity lesions in the bilateral periventricular deep white matter. Diffusion-weighted image (C) reveals diffuse high-signal-intensity lesions in the bilateral periventricular deep white matter. Corresponding ADC map (D) demonstrates low-signal-intensity in the bilateral periventricular deep white matter. Toshibumi Kinoshita et al.
