Purpose: To assess the impact of a blood-pool contrast agent (Gadofosveset) and water-selective excitation for high spatial resolution and high contrast visualization of brain arteries and veins. Materials and Methods: 48 patients (46±17 years old) scheduled for brain MRI including the assessment of the brain vessels (arteries and veins, i.e. prior to brain surgery etc) were included. 24 patients received standard extracellular Gd-DOTA (Dotarem®, 0.1mmol/kgBW) and 24 received the blood-pool contrast agent Gadofosveset (Vasovist®). All patients were investigated with two high spatial resolution gradient echo sequ…
