Journal articleKöhler U, Marshall I, Robertson MB, et al., 2001,
MRI measurement of wall shear stress vectors in bifurcation models and comparison with CFD predictions.
, J Magn Reson Imaging, Vol: 14, Pages: 563-573, ISSN: 1053-1807Steady fluid flow was studied in a simple bifurcation model and in a physiologically realistic model of the human carotid bifurcation. Wall shear stress (WSS) vectors were calculated from phase-contrast (PC) magnetic resonance imaging (MRI) measurements of the velocity field. Velocity measurements in the inflow regions were also used as boundary conditions for computational fluid dynamics (CFD) calculations of WSS, which were compared with those derived from MRI alone. In regions of well-behaved flow, MRI and CFD estimates of WSS were in good general agreement. In regions of disturbed flow, for example near the bifurcation, the quality of the MRI measurements was sufficient for reliable calculation of WSS vectors when a sensitive surface coil was used. The combination of MRI and CFD would seem to be a powerful technique for the investigation of flow phenomena.

Journal articleXu XY, Long Q, Bourne M, et al., 1999,
On the geometrical and flow characteristics of the human aortic bifurcation
, American Society of Mechanical Engineers, Bioengineering Division (Publication) BED, Vol: 42, Pages: 725-726The effect of branching non-planarity on the local blood flow pattern and wall shear stress distribution was investigated using a combination of magnetic resistance (MR) imaging and computational fluid dynamics (CFD) techniques. MR measurements of the vascular geometry and velocities at selected sites of the aortic bifurcation of a healthy subject were made. Flow patterns at the bifurcation were reconstructed using a CFD solver. A comparison was also made with results obtained for the same bifurcation geometry but with a planar assumption.
