Summary
Four-dimensional phase contrast MRI (4D flow) offers advanced cardiovascular blood flow assessment. Streamlined acquisition and processing now make 4D flow a practical tool for pediatric cardiovascular imaging.
Area of Science:
- Cardiovascular Imaging
- Medical Physics
- Pediatric Cardiology
Background:
- Four-dimensional phase contrast MRI (4D flow) is a powerful tool for assessing cardiovascular blood flow.
- Historically, long scan times and complex processing limited its clinical use.
- Recent advancements have improved acquisition speed and post-processing efficiency.
Purpose of the Study:
- To promote wider adoption of 4D flow in clinical practice.
- To detail the clinical utility, acquisition, optimization, and post-processing of 4D flow.
- Focus on its application in pediatric cardiovascular imaging.
Main Methods:
- Utilizing time-resolved, three-dimensional MRI acquisitions.
- Gating scans to the cardiac cycle for accurate flow dynamics.
- Employing advanced post-processing techniques for hemodynamic parameter extraction.
Main Results:
- 4D flow provides comprehensive visualization of blood flow.
- Enables both qualitative and quantitative assessment of hemodynamics.
- Facilitates evaluation of cardiovascular disease impact on flow.
Conclusions:
- 4D flow is increasingly clinically useful due to improved efficiency.
- It guides management in congenital and acquired heart disease.
- This communication serves as a guide for its implementation in pediatric settings.
