Figure 2.

Three punctate acute ischemic infarcts, two lesions in the postcentral gyrus (medial and lateral) and one lesion in the lateral part of the precuneus are depicted on the left hemisphere. The acute infarct in the medial postcentral gyrus (red arrow) shows better lesion conspicuity on the acq2000 and the syn1000, syn1500, syn2000 and syn2500 images compared to the acq1000 image. The lesion conspicuity of the acute infarcts in the lateral part of the postcentral gyrus and in the precuneus is comparable on acq1000, acq2000 (yellow arrows) and syn1000 image (yellow arrow), but slightly reduced on syn1500 (yellow arrows with white border) images. The lesion (white arrows) is not reliably identified on syn2000 and syn2500 due to similar appearance of hyperintensities of uncertain origin (green arrows) in the normal cortex thus also resulting in reduced lesion conspicuity.
