Contrast - in cardiac magnetic resonance imaging

Area of Science:

• Cardiovascular Imaging
• Radiology
• Cardiology

Background:

• Cardiac magnetic resonance (CMR) is a recognized non-invasive diagnostic tool for cardiovascular disease.
• Late gadolinium enhancement (LGE) significantly improves CMR's capability to provide structural, functional, and prognostic data.

Purpose of the Study:

• To review the applications of gadolinium-based contrast agents in CMR.
• To highlight how LGE patterns aid in non-invasive diagnosis and management of cardiovascular conditions.

Main Methods:

• Utilizing gadolinium as an extracellular contrast agent for myocardial tissue characterization.
• Analyzing LGE patterns to differentiate various cardiomyopathies and cardiac masses.
• Evaluating the role of LGE-CMR in risk stratification for sudden cardiac death.

Main Results:

• Gadolinium distribution detects myocardial edema, fibrosis, and infiltration.
• LGE patterns allow for non-invasive differentiation of cardiomyopathies.
• LGE-CMR assists in decisions regarding implantable cardioverter-defibrillator therapy in hypertrophic cardiomyopathy.

Conclusions:

• LGE-CMR is crucial for diagnosing and characterizing diverse cardiovascular pathologies.
• This technique enhances diagnostic accuracy for cardiac masses, distinguishing neoplastic from non-neoplastic conditions.
• Gadolinium-based contrast agents are integral to advanced CMR applications.
