Pulmonary hypertension is a rare progressive disorder characterised by elevated pulmonary artery pressure leading to right ventricular failure and death. Native T1 mapping is a CMR technique for myocardial tissue characterisation that does not require MRI contrast administration1. We investigated whether native T1 values relate to invasive pressure measurements and markers of RV dysfunction in patients with pulmonary hypertension.
