Fig. 1. Magnetic resonance images of patient 1. A. A T2-weighted fluid-attenuated inversion recovery (FLAIR) image, the axial plane. The image shows a periventricular lesion in the posterior horn of the left lateral ventricle (marked by the red oval). B. A susceptibility-weighted (SW) image, the axial plane. The image shows a central vein sign in the lesion near the posterior horn of the left ventricle (marked by the red oval). C. A susceptibility-weighted (SW) image; the sagittal plane, the central vein sign appears as a dot in the lesion (marked by the red oval). D. A susceptibility-weighted (SW) image, the coronal plane; the central vein sign appears as a thin line in the same lesion (marked by the red oval)
Fig. 2. Magnetic resonance images of patient 2. A. A T2-weighted fluid-attenuated inversion recovery (FLAIR) image, the axial plane. The image shows a round lesion in the deep white matter of the left frontal lobe (marked by the red oval). B. A susceptibility-weighted (SW) image, the axial plane. The image shows the same lesion, the central vein sign is not visualized (the red oval). C. A susceptibility-weighted (SW) image, the sagittal plane. The same lesion, the central vein sign is not visualized; a smaller lesion not suitable for the analysis is located in close proximity (the red oval). D. A susceptibility-weighted (SW) image, the coronal plane. The same lesion, the central vein sign is not visualized (the red oval)
