Four-dimensional flow MRI offers a comprehensive assessment of lung perfusion in hemi-Fontan patients, surpassing the capabilities of traditional two-dimensional flow imaging for evaluating systemic-to-pulmonary collateral blood flow.
Area of Science:
- Cardiovascular Imaging
- Medical Physics
Background:
- Accurate lung perfusion quantification is critical for managing patients post-hemi-Fontan surgery.
- Two-dimensional cardiac magnetic resonance phase contrast flow (2D Flow) is a non-invasive method to assess systemic-to-pulmonary collateral blood flow.
Observation:
- This case report highlights the application of advanced imaging techniques in a clinical setting.
- Comparison between 2D Flow and 4D Flow MRI was performed.
Findings:
- Four-dimensional flow MRI (4D Flow) provides a more comprehensive assessment of lung perfusion compared to 2D Flow.
- 4D Flow offers superior visualization and quantification of collateral blood flow in hemi-Fontan patients.
Implications:
- 4D Flow MRI may become a valuable tool for optimizing the management of hemi-Fontan patients.
- Enhanced non-invasive assessment can lead to improved clinical decision-making and patient outcomes.
