Magnetic Resonance Angiography of the neck area in the mouse:

A time-of-flight 3D image of the large arteries in the neck area of the mouse is shown. The two parallel carotid arteries that branch off the aorta and bring blood to the brain can be seen. The bifurcation in each of the carotid arteries is easily identifiable. This MRI method is based on fast flowing protons therefore only arterial blood is detected.
