The Diagnostic Ability of rs-DWI to Detect Subtle Acute Infarction Lesion in the Different Regions of the Brain and the Comparison between Different b-Values

Figure 5

A 47-year-old male patient with acute cerebral infarctions. (a), (b), and (c) were the ss-DWI image with b-values 1000, 2000, and 3000. Two lesions were found at b1000 image. The parietal lesion (black arrow) kept the signal while the b-value was increasing, which should be an infarction lesion. However the frontal lesion (white arrow) decreased the signal while the b-value was increasing, which should be a demyelinating lesion. Noise looked more pronounced in b3000 than b2000.
