Fig 1 Anterior-posterior views of the optical flow method estimation of blood flow overlaid on digital subtraction angiography (DSA) images with color code. a and c, The red and green colors indicate high flows in feeding arteries, nidus, and draining veins of the arteriovenous malformation before embolization on (a) arterial and (c) venous phases. b and d, After embolization, the hemodynamics change toward normalization and fewer high-flow components are illustrated.
