Computational workflow to parameterize and analyze the PAs. (a) Longitudinal path-lines of the PAs are segmented from MR images. (b) Segmented lines are applied to reconstruct the geometry of the PAs, which is meshed using triangular elements in the 3D space. (c) Material axes are generated in the PAs. (d) Diameter waveform is obtained from PC-MRI of the MPA. (e) Pressure waveform at the MPA is acquired from catheterization. (f) Instantaneous P-D relation is reconstructed from the pressure and diameter waveforms. By the FE developments (a-c) and the clinical measurements (d-f) the characterization was carried out.
