Brain MR venograpy based on phase-contrast technique (MRV) contributes in the diagnosis of venous sinus thrombosis and helps to clarify venous anatomy before brain operations. However, MRV is not commonly taken in routine brain MRI examinations because it requires a longer acquisition time. Recently, Compressed SENSE, which is a combination of compressed sensing and parallel imaging technique: SENSE, has been developed, and can shorten acquisition times with minimum image quality deterioration. Therefore, we investigated the optimization of 1 minute MRV, which the acquisition time was 1 minute, using Compressed SENSE at 3T.
