Key result
Velocity-encoded cine MR imaging demonstrated that patients with pulmonary hypertension have lower peak systolic velocity and greater retrograde flow compared to healthy subjects.
Why the study?
Can velocity-encoded cine MR imaging accurately assess pulmonary flow patterns and estimate pulmonary vascular resistance in patients with pulmonary hypertension?
Cross-Sectional (n=21)
Can velocity-encoded cine MR imaging accurately assess pulmonary flow patterns and estimate pulmonary vascular resistance in patients with pulmonary hypertension?
Velocity-encoded cine MR imaging can noninvasively demonstrate inhomogeneous flow profiles and estimate pulmonary vascular resistance in patients with pulmonary hypertension.
No takes yet. Share an insight, caveat, or question.
May support noninvasive MR assessment of pulmonary flow in PH; leaves open validation for PVR estimation.
Kondo et al. (1992) conducted a cross-sectional in Pulmonary hypertension (n=21). Velocity-encoded cine MR imaging vs. Doppler echocardiography and healthy subjects was evaluated on Pulmonary flow and flow patterns (peak systolic velocity, retrograde flow). Velocity-encoded cine MR imaging demonstrated that patients with pulmonary hypertension have lower peak systolic velocity and greater retrograde flow compared to healthy subjects.
