Figure 2From: Inflow-weighted pulmonary perfusion: comparison between dynamic contrast-enhanced MRI versus perfusion scintigraphy in complex pulmonary circulationInfluence of integration range ti on rPBViw. Correlation coefficient between PBViw L% (ti) and PS L% reached maximum value of 0.981 at ti − 0.3sec, which is almost the time-to-peak (ti =0). We used time-to-peak tmax as the upper bound for inflow-weighted analysis of DCE-MRI.Back to article page
