In this study, we demonstrated the feasibility of noninvasively quantifying stenosis grade and pressure differences in congential heart disease patients with aortic coarctations or pulmonary artery stenosis using a radially undersampled 4D PC-MRI sequence. Anatomical measurements were compared with CE-MRA and pressure measurements were compared with Doppler ultrasound.
