Quantitative evaluation of chronic pulmonary thromboemboli by multislice CT compared with pulsed Tissue Doppler Imaging and its relationship with brain natriuretic peptide

TVOI was better correlated with RVSP (R = 0.401) than the other parameters (Sw, Ew, E/Ew, and BNP), and this was similar to the degree that BNP was correlated with RVSP (R = 0.390). TVOI can be a better indicator of RVSP than LVOI. CT VOI may be a useful parameter to assess CPATE morphologically.
