Inclusion Criteria Patients: - Clinical referral for cMRI in the absence of any contraindication to cMRI - Flow measurements are part of the clinical cMRI protocol - Signed informed consent of participants and/or legal representatives according to current ethical rules and regulations for children and adults - For females in reproductive age, exclusion of pregnancy by a pregnancy test conducted before the cMRI Exclusion Criteria Patients: - Any contraindication for undergoing a cMRI examination or for receiving gadolinium contrast media (renal failure, allergy) per internal institutional policy of University Children's Hospital Zurich - Any intrathoracic device causing imaging artifacts - Medical condition at time of examination that would make additional study-related MR scans an unjustified burden or risk. - Inability or unwillingness to provide informed consent. Inclusion Criteria Healthy Controls: - Absence of any contraindication to cMRI - Signed informed consent of participants according to current ethical rules and regulations - For females in reproductive age, exclusion of pregnancy by a pregnancy test conducted before the cMRI. Exclusion Criteria Healthy Controls: - Any contraindication for undergoing a cMRI examination per internal institutional policy of University Children's Hospital Zurich |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Feasibility of data processing | Comparison of flow velocities and blood flow measured by 4D flow cMRI pulse sequences against phantom corrected 2D cMRI data. | Within 72 hours after completion of exam | |
Secondary | Image quality | Qualitative grading of 4D flow cMRI anatomical images for image quality using a numerical scale. | Within 72 hours after completion of exam | |
Secondary | Comparability | Qualitative grading of comparability of anatomical findings in 4D flow cMRI anatomical images with contrast-enhanced MR angiography images, if these have been acquired during the clinical examination of patients, using a numerical scale. | Within 72 hours after completion of exam | |
Secondary | Clinical value | Qualitative grading of clinical and diagnostic value of visualizations of flow dynamics using a numerical scale. | Within 72 hours after completion of exam |
