Vascular imaging acquisition techniques to extract veins and arteries are not impervious to flaws: venography by susceptibility weighted imaging is prone to blooming effects and false-negatives, and angiography from time-of-flight imaging is affected by veins detection and false-negatives. They also fail to provide quantitative measures of vascular physiology such as flow and susceptibility important for understanding the origin of vascular-based biases. Thus, we aimed to employ multi-orientation quantitative susceptibility mapping, multi-echo time-of-flight and quantitative phase-contrast to more accurately detect and quantify the susceptibility and flow along the vascular tree, paving the way for a joint anatomical/physiological vascular atlas at 7T.
