Key result
Supine cross-table lateral chest roentgenograms demonstrated greater sensitivity for detecting pericardial effusions compared to conventional lateral chest roentgenograms (51% vs 31%).

Does supine cross-table lateral chest roentgenogram improve the detection of pericardial effusion compared to conventional lateral chest roentgenogram in patients with suspected pericardial effusion?
Absolute Event Rate: 51% vs 31%
Supine cross-table lateral chest roentgenograms offer higher sensitivity than conventional lateral films for detecting pericardial effusions, particularly large ones.
James A. Heinsimer (1987) conducted an observational in Suspected pericardial effusion. Supine cross-table lateral chest roentgenogram vs. Conventional lateral chest roentgenogram was evaluated on Sensitivity for the detection of pericardial effusion. Supine cross-table lateral chest roentgenograms demonstrated greater sensitivity for detecting pericardial effusions compared to conventional lateral chest roentgenograms (51% vs 31%).
