Key result
Noncontrast electron beam tomography visualized at least one pericardial sinus or recess in 97.2% of patients without known pericardial disease, with a mean total volume of 3.3 +/- 2.2 mL.
Why the study?
Does noncontrast electron beam tomography accurately evaluate the attenuation, size, and volume of pericardial sinuses and recesses in patients without known pericardial disease?
Observational (n=213)
Does noncontrast electron beam tomography accurately evaluate the attenuation, size, and volume of pericardial sinuses and recesses in patients without known pericardial disease?
Noncontrast EBT frequently and clearly depicts physiological fluid collections in pericardial sinuses and recesses, aiding in differentiating them from pericardial effusions and mediastinal lymph nodes.
No takes yet. Share an insight, caveat, or question.
Noncontrast EBT depiction of normal pericardial sinuses may prevent misinterpretation as effusion; leaves open validation against other modalities in prospective studies.
Budoff et al. (2000) conducted an observational in Without known pericardial disease (n=213). Electrocardiographically triggered noncontrast-enhanced electron beam tomography (EBT) was evaluated on Visibility, attenuation, and volume of the pericardial sinuses and recesses. Noncontrast electron beam tomography visualized at least one pericardial sinus or recess in 97.2% of patients without known pericardial disease, with a mean total volume of 3.3 +/- 2.2 mL.
