Figure 2

Apparent diffusion coefficient map with colour shades (A), diffusion-weighted imaging (B) and T2-weighted image (C) from one representative patient at seven hours after cardiac arrest. Regions of low apparent diffusion coefficient (ADC) showed a blue colour; in contrast, regions of high ADC showed a white colour. The colour shades on the ADC maps identified the pixel showing the minimum ADC value in each brain region. A 3D cursor (arrow) was used to select the predefined spot (right thalamus) simultaneously in the three different sequences, and it can be easy to mark the area with the minimum ADC on the ADC maps based on the T2-weighted image (T2WI) and diffusion-weighted imaging (DWI). The circular region-of-interest (ROI) cursors were positioned on the areas with the minimum ADC in each brain region. Severely restricted diffusion within the ROIs was shown in the caudate nucleus (0.238 × 10-3mm2/sec), putamen (0.299 × 10-3mm2/sec), thalamus (0.290 × 10-3mm2/sec), and occipital grey matter (0.184 × 10-3mm2/sec) but not in the occipital white matter (0.712 × 10-3mm2/sec).
