As an ECG-gated non-contrast MRA technique, FBI enables
the visualization of peripheral arterials by utilizing
the physiological signal differences between two cardiac
phases: systolic and diastolic phases. It is desirable
to depict the vascular inflow effects and to obtain more
insightful information on vascular physiology by the
time-resolved FBI technique. In this work, we
demonstrate the feasibility of an accelerated
time-resolved non-contrast FBI MRA technique using
compressed sensing, besides, the image reconstruction
time was significantly reduced using coil compression.
