Figure 1From: Inflow-weighted pulmonary perfusion: comparison between dynamic contrast-enhanced MRI versus perfusion scintigraphy in complex pulmonary circulationSchematic plot of integration range for PBV and inflow-weighted analysis. Arrowhead indicates the upper bound of integration for rPBV. The arrow indicates tmax, time-to-peak for the normal lung parenchyma, which was defined as the upper bound of integration for inflow-weighted analysis.Back to article page
