Overview

• A study published in *Open Heart* confirms that 4D flow MRI outperforms traditional echocardiography in diagnosing aortic stenosis, a potentially fatal heart condition.
• The advanced imaging technique captures blood flow in three dimensions over time, providing a more comprehensive and reliable assessment of disease severity.
• The study involved 30 patients and validated 4D flow MRI findings against eight-month clinical outcomes, demonstrating its real-world diagnostic value.
• Traditional echocardiography often underestimates the severity of aortic stenosis, delaying critical surgical interventions, a gap addressed by 4D flow MRI.
• The research, funded by Wellcome and conducted across multiple UK and European institutions, highlights the potential to save thousands of lives with earlier and more accurate diagnoses.
