MR angiography (MRA) of fingers is challenging due to the small size of blood vessels. Though high-resolution MRA may be obtained with dedicated RF coils, the associated long scan time and limited coverage hinder applications. Therefore, we evaluated the feasibility of applying compressed sensing on high-resolution finger MRA to save scan time. Our results show that compressed sensing can significantly reduce scan time while preserving blood vessel information, facilitating the clinical application of high-resolution finger MRA. Accelerated high-resolution finger MRA with compressed sensing should be useful for the diagnostic evaluation and pathogenesis studies of systemic sclerosis and arthritis.
