<unk>  (PC-MRI) is a specific type of magnetic<unk><unk>  used primarily to determine flow velocities. PC-MRI can be considered a method of Magnetic<unk>  Velocimetry. It also provides a method of magnetic<unk>  angiography. Since modern PC-MRI is typically time-resolved, it provides a means of 4D<unk>  (three spatial dimensions plus time).
