Susceptibility weighted imaging (SWI), acquiring both magnitude and phase information for tissues using a 3D gradient-recalled echo sequence, is advantageous to detect microhemorrhages and microvasculature and useful in diagnosing small vessel diseases etc., but can be suffering from the long acquisition time. This study evaluated the effectiveness of brain SWI accelerated by compressed SENSE (CS-SENSE), and the CS-SENSE factor 4 is recommended in routine practice. Besides, the CS-SENSE factor 10 maybe a fast surrogate for distinguishing CMBs but sacrificing SN-RN visualizations.
