So far, magnetic resonance angiography (MRA) of rodents has only been performed by using time-of-flight (TOF) MRI techniques. This is because applications of first-passage contrast agents as in humans are hampered by pronounced physiologic differences (blood volume and heart beat rate). Here we describe the use of low-dose Gd-DOTA to enhance the performance of TOF MRA in rat brain. While no improvement in contrast was achieved, the measuring time could be reduced by almost a factor of three. This decrease in total acquisition time has been used to study the impact of a model of ligatured common carotid on the upper part of the blood system of the rat.
