Measurements and pulmonary blood volume (PBV) results from one patient. A Measurement of pulmonary transit time (PTT) from the pulmonary transit time pulmonary artery-left atrium (CoG(PA-LA)). B First-pass perfusion (FPP) method from the PROVE-HF study [4] using pulmonary transit beats (PTB(FPP)). Panel C shows the FPP peak-peak method (peak-peak(FPP)). D FPP center-of-gravity (CoG(FPP)) method. The blue lines indicate contrast intensity measurement in the pulmonary artery (A) or basal right ventricle (B, C and D); red lines indicate measurement in the left atrium (A) or basal left ventricle (B, C and D). CO cardiac output; RVSV right ventricular stroke volume
