Corrected MRI Pulmonary Transit Time for Identification of Combined Precapillary and Postcapillary Pulmonary Hypertension in Patients With Left Heart Disease.BACKGROUND
 To investigate the diagnostic value of MRI-derived corrected pulmonary transit time (PTTc) in PH-LHD sub-grouped according to hemodynamic phenotypes.


 In patients, right heart catheterization (RHC) and MRI were performed within 30 days. 
MRI
In patients, right heart catheterization (RHC) and MRI were performed within 30 days.  Our findings have potential to improve selection for invasive RHC for PH-LHD patients.
