Wearing a necktie is mandatory in several professions. However, the constant restriction of the veins (and potentially arteries) might lead to adverse side-effects, which could already be visualized regarding intraocular pressure. In this study, the effects of a tight necktie are investigated using Arterial Spin Labeling to measure brain perfusion and venous phase-contrast angiography to show changes in venous flow velocities.
