[Imaging of the pericardium using magnetic resonance]

Area of Science:

• Cardiovascular Imaging
• Radiology
• Medical Diagnostics

Context:

• Advancements in sectional imaging, particularly magnetic resonance imaging (MRI), have renewed interest in pericardial evaluation.
• Improved image quality, faster acquisition, and cine display capabilities enhance MRI's utility in assessing the pericardium.
• This article draws upon extensive clinical experience with MRI of the pericardium in a large patient cohort.

Purpose:

• To review the anatomy of the normal pericardium and discuss various MRI techniques for its evaluation.
• To highlight the advantages of MRI in specific clinical scenarios involving the pericardium.
• To cover congenital anomalies and acquired pericardial diseases, including effusions, thickening, and tumors.

Summary:

• The review covers normal pericardial anatomy, MRI techniques, and congenital anomalies.
• Emphasis is placed on acquired conditions like pericardial effusions, characterizing fluid collections, and differentiating constrictive pericarditis from restrictive cardiomyopathy.
• Primary and metastatic pericardial tumors are also described.

Impact:

• MRI provides a comprehensive assessment of normal and abnormal pericardial structures.
• It aids in differentiating various pericardial conditions, including effusions, thickening, constrictive pericarditis, and tumors.
• This imaging modality is crucial for accurate diagnosis and management of pericardial diseases.
