FIG 1. Case of a 62-year-old patient with aphasia and right hemiparesis. (A) CT scans obtained 100 minutes after symptom onset, (B) DW images obtained 120 minutes after symptom onset, and (C) follow-up FLAIR images. DW images were rated positive by all raters and show hyperintensity in the left MCA territory. CT scans were rated normal by five of the six raters. With the knowledge of the DW images, there might be a subtle hypoattenuation in the left insular ribbon region on CT scans. However, the follow-up FLAIR images reveal only small ischemic leasons of the left insular ribbon and parietal regions, with normalization of large parts of the former diffusion-restricted area.
