A and B, Integral rendered CTCVI scans show detailed cortical venous anatomy, including the anastomotic veins of Trolard (small closed arrows), the superior sagittal sinus (large straight arrow), and the transverse (open arrows) and occipital (curved arrow) sinus.
C, The same data can be segmented to isolate the circle of Willis.
D, Integral rendering with sagittal cut planes reveals the patent sylvian aqueduct (arrow) and corpus callosum (asterisk), again from the same 60-second scan. Note the deep cerebral artery and venous detail.
