The simultaneous depiction of both arterial and venous vasculature has recently been demonstrated by using multi-echo sequences. We quantitatively and qualitatively assessed the simultaneous representation of intracranial arteries and veins at a higher resolution than previously reported using a customized 3D spoiled gradient multi-echo sequence at 7T. Such custom sequence had an overall better capability of depicting the arterial vasculature compared to conventional time-of-flight (TOF) arteriography. On the contrary, veins were in general better depicted by conventional susceptibility-weighted venography, however the custom multi-echo sequence provided superior quality images of the superficial veins.
