Magnetic resonance imaging of XXXX .

@entity1 @entity32 @entity3255 @entity730 @entity358 @entity85
Gated magnetic resonance imaging of 5 @entity1 with suspected @entity3255 was performed using a superconducting magnet operating at 0.35 Tesla. Results were compared with those of echocardiography and hemodynamic measurements in all @entity1 , with chest films in 5, computerized tomography in 2 and with histologic findings in 3. Pericardial thickness exceeded 5 mm in 4 @entity1 and was 5 mm in 1 @entity1 . Absence of magnetic resonance signal from the thickened pericardium was observed with extensive @entity730 , and increased intensity of the thickened pericardium was associated with @entity32 . Dilatation of the right atrium, venae cavae and hepatic veins, and right ventricular narrowing was observed in all @entity1 . The ventricular septum was straight in all @entity1 . Magnetic resonance imaging allows both measurement of pericardial thickness and depicts internal cardiac anatomy without exposure to radiation or use of contrast medium. Satisfactory imaging with a large field of view can be performed in the presence of @entity358 , @entity85 or surgical "hardware"--conditions that limit echocardiography and computerized tomography. The inherently 3-dimensional data permit imaging in any plane without loss of resolution. Thus, magnetic resonance appears to be the noninvasive method of choice for the diagnosis of @entity3255 .
