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 4

A 49-year-old male patient with acute cerebral infarction showed increased specificity for high b-value. (a) On ss-DWI image with b1000, 6 subtle infarcts were found. With (b) ss-DWI image with b2000 and (c) ss-DWI image with b3000, only 4 lesions (black arrows) were confirmed and 2 lesions with white arrows were false positive at b1000.
