Three-dimensional, time-resolved (4D) relative pressure mapping using magnetic resonance imaging

J Magn Reson Imaging. 2000 Aug;12(2):321-9. doi: 10.1002/1522-2586(200008)12:2<321::aid-jmri15>;2-2.


We describe here a method for generating relative pressure maps from magnetic resonance velocity data in three spatial and one temporal dimension (4D). The relative pressure map calculated for pulsatile flow in a compliant phantom was shown to be consistent with independent pressure transducer measurements. The feasibility of performing 4D pressure mapping in vivo is also demonstrated.
