Occlusion of lenticulostriate arteries (LSAs) were reported to lead to lacunar infarction. Currently, the major technique to image LSAs is digital subtraction angiography (DSA) for its high resolution and good definition of small vessels. For MRI, qualified images of LSAs can only be acquired from 7T scanners in recent studies. In this abstract, we optimized a technique independent of in-flow effect called flow-sensitive black-blood (FSBB). With this optimized method, qualified images of LSAs can be achieved on a 3T scanner, which makes it more practical for imaging LSAs using MRI in clinical applications.
