Figure 2

4D flow MRI complex difference (CD) maximum intensity projections and centerlines (CLs) used to assess distal arterial (red) and internal carotid artery (ICA; blue) pulsatility. The waveforms represent group-averaged ICA and distal flows after interpolation and normalization (division by the means). The schematic shows how the CD, CLs, and velocities (\({\text{V}}_{x}\), \({\text{V}}_{y}\), \({\text{V}}_{\text{z}}\)) were used for automatic distal arterial waveform extraction and manual seed-point based waveform extraction in ICA and middle/posterior cerebral arteries (MCA/PCA).
