SWI is a technique that utilizes the magnetic susceptibility differences between tissues to highlight small blood vessels. Its clinical use for high spatial resolution is challenged by scan time. This work proposes the use of a displaced UFLARE for susceptibility weighted imaging that affords high spatial resolution and scan time reduction. UFLARE acquires a train of refocused echoes that are independently phase encoded. SWI contrast is accomplished by using an extra evolution time between the initial excitation pulse and the first refocusing pulse. Its applicability for high spatial resolution was examined in volunteer studies at a 3.0 and 7.0 T.
