Cardiovascular magnetic resonance elastography: A review

Area of Science:

• Cardiovascular research
• Biomedical engineering
• Medical imaging

Background:

• Cardiovascular diseases are a leading global cause of death.
• Altered myocardial and aortic stiffness is linked to various conditions, including hypertension, ischemia, and aneurysms.
• Tissue stiffness can serve as a crucial biomarker for conditions like preserved ejection fraction diastolic dysfunction and aortic aneurysm rupture potential.

Purpose of the Study:

• To review the technical aspects of magnetic resonance elastography (MRE).
• To highlight the applications of MRE in quantifying myocardial and aortic stiffness.
• To discuss the role of MRE in assessing various cardiovascular disease states.

Main Methods:

• Magnetic Resonance Elastography (MRE) is a non-invasive phase-contrast magnetic resonance imaging technique.
• MRE measures the mechanical properties of tissues, specifically stiffness.
• This review synthesizes existing literature on MRE's technical details and clinical applications.

Main Results:

• MRE enables non-invasive quantification of myocardial stiffness.
• MRE allows for non-invasive assessment of aortic stiffness.
• The technique provides valuable data for diagnosing and managing cardiovascular diseases.

Conclusions:

• Magnetic Resonance Elastography (MRE) is a promising non-invasive tool for assessing cardiovascular mechanical properties.
• Quantifying myocardial and aortic stiffness using MRE can aid in the diagnosis and management of various cardiovascular diseases.
• Further research and clinical integration of MRE are warranted to leverage its full potential in cardiovascular medicine.
