Metastases to the heart and pericardium are much more common than primary cardiac tumors and are generally associated with a poor prognosis. Tumors that are most likely to involve the heart and pericardium include cancers of the lung and breast, melanoma, and lymphoma. Tumor may involve the heart and pericardium by one of four pathways: retrograde lymphatic(More)
BACKGROUND Prediction of perioperative cardiac complications is important in the medical management of patients undergoing noncardiac surgery. However, these patients frequently die as a consequence of primary or secondary multiple organ failure (MOF), often as a result of sepsis. We investigated the early perioperative risk factors for in-hospital death(More)
PURPOSE To compare computed tomographic (CT) window settings selected by radiologists with those determined by using two alternative approaches for depiction of pulmonary emboli (PE). MATERIALS AND METHODS Institutional review board approval was obtained; informed consent was not required. This study was compliant with the Health Insurance Portability and(More)
Naive Bayesian learning has been popular in data mining applications. However, the performance of naive Bayesian learning is sometimes poor due to the unrealistic assumption that all features are equally important and independent given the class value. Therefore, it is widely known that the performance of naive Bayesian learning can be improved by(More)
The purpose of this prospective, pilot study was to determine whether differences in myocardial T2 relaxivity can be identified among active systemic lupus erythematosus (SLE) patients with clinically suspected SLE myocarditis, other active SLE patients, inactive SLE patients and age and gender matched controls. Eleven consecutive female patients (six with(More)
OBJECTIVE This study sought to determine the transesophageal echocardiographic features and natural history of patients with aortic intramural hematoma. METHODS The transesophageal echocardiograms of all patients who had symptoms indicative of aortic dissection over 6 years were reviewed. Measurements were made of the involved aortic segment in the study(More)
OBJECTIVE The objective of our study was to compare accuracies of axial, multiplanar, and 3D volume-rendered images in the diagnosis of thoracic aortic anomalies in pediatric patients and young adults. MATERIALS AND METHODS Fourteen patients, 17 days to 20 years old, with thoracic aortic anomalies underwent MDCT using axial, multiplanar, and 3D(More)
PURPOSE To determine how often emboli detected angiographically in peripheral pulmonary arterial branches would be missed with cross-sectional imaging. MATERIALS AND METHODS Seventy-nine of 88 consecutive pulmonary angiograms interpreted as positive for pulmonary emboli were reviewed retrospectively to detect pulmonary emboli. Three angiograms interpreted(More)
OBJECTIVE Our objective was to study the ability of three-dimensional MR angiography with retrospective respiratory gating to reveal stenoses in proximal coronary arteries on source and projection images. CONCLUSION Proximal coronary artery stenoses can be identified using three-dimensional MR angiography with retrospective respiratory gating, both with(More)
