Human African Trypanosomiasis is a parasitic disease that causes progressive blood brain barrier breakdown. We have developed a non-invasive high SNR ASL technique (mbASL) combined with bipolar diffusion gradients to determine the ratio of intravascular to extravascular signal from the brain. The ratio of this signal will change in a mouse brain infected with HAT due to the barrier breakdown. We have imaged this changing brain along with producing CBF maps, thus using a novel method in imaging a HAT infected mouse.
