The impairment of microvessels can lead to neurologic diseases such as stroke and vascular dementia. The imaging of perforating arteries requires an extremely high resolution due to their small caliber size. In this study, we optimized the parameters of compressed sensing (CS) TOF-MRA to achieve isotropic 0.2 mm lenticulostriate artery (LSA) images within 10 minutes at 7T. More LSA stems and branches were delineated in CS TOF images compared with conventional TOF images. CS TOF-MRA can be a state-of-the-art method for detecting microvasculopathies of cerebral vascular diseases.
