[Imaging of the pericardium using magnetic resonance]

Evaluation of the pericardium has been rediscovered with the advent of sectional imaging modalities such as magnetic resonance. Owing to the improved image quality, faster imaging and cine display, MRI has proved to have a useful role in assessment of the pericardium. This article illustrates the authors' wide experience with MRI of normal and abnormal pericardium in numerous patients. The anatomy of the normal pericardium is reviewed, as are the different MR imaging techniques used Advantages of MRI in specific situations are discussed. Congenital anomalies are covered but particular attention is paid to acquired diseases, such as pericardial effusions, with emphasis on the characterization of the different pericardiac fluid collections. Pericardial thickening and constrictive pericarditis, which are easily differentiated from restrictive cardiomyopathy, are also discussed. Finally, primary and metastatic tumors are described.
