Magnetic Particle Imaging for High Temporal Resolution Assessment of Aneurysm Hemodynamics
Fig 3
Cyclic repetition of the 4D pc-fq MRI (top) shows distinct pulsation and a much lower flow velocity inside the aneurysm.
Dynamic MRI (second top, cubic spline interpolated), MPI (second bottom), and DSA (bottom) also show distinct pulsation and delayed contrast agent dynamics inside the aneurysm. Regions were chosen in the corresponding image data as depicted in Fig 1. Pulsations and bolus injections did not perfectly match between the different methods, due to the resetting of the experiments.
