Practical Guide to Evaluating Myocardial Disease by Cardiac MRI

Area of Science:

• Cardiology
• Medical Imaging
• Biomedical Engineering

Background:

• Myocardial disorders arise from diverse causes like ischemia, genetic factors, and systemic diseases.
• Cardiac MRI (CMR) is crucial for identifying, assessing prognosis, and guiding therapy for myocardial conditions.
• CMR offers functional assessment and tissue characterization without ionizing radiation, distinguishing it from other modalities.

Purpose of the Study:

• To review the role of cardiac MRI in diagnosing and managing myocardial disorders.
• To highlight the advantages of CMR over other imaging techniques.
• To discuss emerging CMR techniques and their potential impact on understanding myocardial pathophysiology.

Main Methods:

• Review of current cardiac MRI sequences including balanced steady-state free precession and late gadolinium enhancement.
• Evaluation of advanced techniques such as mapping, MR spectroscopy, and fingerprinting.
• Discussion of specific sequences like perfusion imaging, T2*, real-time cine, and T2-weighted imaging for clinical scenarios.

Main Results:

• Standard CMR sequences are vital for diagnosis, prognosis, and therapeutic management of ischemic and non-ischemic myocardial diseases.
• Newer techniques like mapping provide additional diagnostic information beyond conventional methods.
• Emerging technologies like MR spectroscopy and fingerprinting are expected to significantly advance the understanding of myocardial disorder mechanisms.

Conclusions:

• Cardiac MRI is indispensable for comprehensive evaluation of myocardial disorders.
• Conventional and advanced CMR sequences are essential for clinical decision-making.
• Novel and emerging CMR techniques hold significant potential to revolutionize the understanding and diagnosis of heart muscle diseases.
