Especially due to its long acquisition times, 4D Flow MRI often remains compromised in a clinical routine setting. Scan acceleration techniques have been proposed to alleviate this issue. In the present work we demonstrate the potential of using highly undersampled 4D Flow MRI reconstructed using k-t PCA in imaging of congenital heart disease patients (CHD). Patients with different pathologies were scanned and initial results prove that volume flow compares well with fully sampled 2D Flow MRI and that particle tracking exhibits additional clinically valuable information.
