Myocardial Perfusion Imaging by Cardiovascular Magnetic Resonance: Research Progress and Current Implementation

Area of Science:

• Cardiology
• Medical Imaging

Background:

• Cardiovascular diseases, particularly coronary artery disease, represent a major global health and economic burden.
• Risk factors like hypertension, diabetes, and obesity contribute to vascular abnormalities and myocardial damage.
• Coronary artery stenosis impairs myocardial perfusion, potentially causing irreversible tissue damage.

Purpose of the Study:

• To review the principles of cardiovascular magnetic resonance (CMR) myocardial perfusion imaging.
• To summarize research progress in CMR myocardial perfusion imaging acquisition and analysis.
• To discuss the clinical implementation of CMR myocardial perfusion imaging.

Main Methods:

• Review of existing literature on CMR myocardial perfusion imaging.
• Focus on principles, acquisition techniques, and analytical methods.
• Examination of clinical applications and diagnostic capabilities.

Main Results:

• CMR myocardial perfusion imaging is a powerful tool for detecting myocardial ischemia.
• Advancements in technology have improved accuracy in evaluating myocardial microcirculation.
• The technique aids in assessing perfusion abnormalities in patients with cardiovascular risk factors.

Conclusions:

• Accurate evaluation of myocardial perfusion is critical for managing cardiovascular disease.
• CMR myocardial perfusion imaging offers a non-invasive method to assess myocardial blood flow and detect ischemia.
• This review highlights the growing role and potential of CMR in clinical cardiology.
