Figure S1 T2-weighted magnetic resonance imaging of fetus with vein of Galen malformation at 28 weeks' gestation, showing significant hydrops. Skin edema, ascites and pleural effusion can be seen in the sagittal view (a) and skin edema and cardiomegaly can be seen in the axial view (b). Videoclip S1 Time-of-flight magnetic resonance imaging of fetal brain with vein of Galen malformation (VGM) at 28 weeks' gestation, showing internal carotid arteries and their connections with posterior and anterior cerebral arteries. Note the posterior arteries that connect to the VGM, as well as the hyperintense signal inside the VGM, indicating high-velocity blood flow. Videoclip S2 Three-dimensional reconstruction of magnetic resonance images of fetal brain with vein of Galen malformation (VGM), produced by segmentation and fusion of time-of-flight (TOF) and T2-weighted half-Fourier acquisition single-shot turbo spin-echo (T2-HASTE) imaging sequences. Main arteries of the brain, including internal carotid arteries, anterior cerebral arteries, posterior communicating arteries and posterior cerebral arteries, were segmented (shown in red). Fusion of the TOF and T2-HASTE signals in a common space of the VGM is shown in blue. Eyes (in white) were used as spatial references for fusion of the different sequences.
