Signs of Increased Intrapericardial Pressure on Chest Computed Tomography: Pictorial Review With Echocardiography, Cardiac Computed Tomography, and Cardiac Magnetic Resonance Imaging Correlation.

We sought to describe incidental imaging features of increased intrapericardial pressure due to pericardial effusion on chest computed tomography (CT) and correlate them with cardiac CT, cardiac magnetic resonance imaging, and echocardiography. It is important for the radiologist to become familiar with imaging findings of increased intrapericardial pressure in the setting of pericardial effusion when identified on chest CT. Recognizing the imaging findings of increased intrapericardial pressure can better guide the care of these patients.
