Contrast-enhanced cardiovascular magnetic resonance imaging

Area of Science:

• Cardiovascular Imaging
• Radiology
• Medical Diagnostics

Background:

• Contrast-enhanced (CE) cardiac magnetic resonance imaging (MRI) and CE-magnetic resonance angiography (MRA) have become essential tools since the early 1990s.
• These techniques are crucial for evaluating cardiac pathologies like ischemic heart disease and inflammatory conditions, as well as the thoracic vasculature.

Purpose of the Study:

• To review the current applications of extracellular gadolinium-based agents in CE cardiovascular imaging.
• To focus on the use of CE-MRI for ischemic heart disease and inflammatory myocardial conditions.
• To highlight the role of CE-MRA in imaging the pulmonary and aortic vasculature.

Main Methods:

• Utilizes recent advances in fast and ultrafast MRI sequences.
• Employs extracellular contrast media for enhanced imaging.
• Focuses on noninvasive measurements of cardiovascular parameters.

Main Results:

• CE cardiac MRI provides detailed assessment of left ventricular function, morphology, myocardial perfusion, microvascular integrity, and viability.
• MRI's high spatial resolution excels in differentiating transmural from nontransmural pathologies.
• CE-MRA offers a safe, noninvasive method for evaluating thoracic vasculature with a large field of view and 3D visualization capabilities.

Conclusions:

• CE cardiovascular imaging, particularly with MRI and MRA, provides comprehensive, noninvasive evaluation of cardiac and vascular diseases.
• These techniques offer superior diagnostic information compared to other modalities, aiding in accurate diagnosis and management.
• The safety profile and detailed anatomical and functional insights make CE-MRI and CE-MRA indispensable in modern cardiovascular diagnostics.
