OS-CMR and native T1 mapping can identify in-vivo microvascular right ventricular dysfunction in patients with pulmonary artery hypertension.
Blunted OS-CMR SI suggests the presence of in-vivo microvascular RV dysfunction in PAH patients. The native T1 in the inferior RV segments is significantly increased in the PAH patients, particularly among the systemic sclerosis associated PAH group.
Raman et al. (Mon,) studied this question.
