Comparison of AUC and PH parameters with and without pathlength correction (PC) in M1 – M4 for biplane views (V1, V2). Each colormap is scaled to the maximum value for each parameter, for each view. Note the lower bounds of each colormap for the pathlength-corrected parameters, which have been adjusted for clarity. Aneurysm ROIs are indicated by the yellow dotted line. The white arrows indicate regions of a greater discrepancy, corresponding to vessel overlap and foreshortening.
