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 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)
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)
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)
PURPOSE The purpose of this study was to determine the lobar distribution and associated radiologic/clinical findings of partial anomalous pulmonary venous return (PAPVR) in the adult population using multidetector computed tomography (MDCT). MATERIALS AND METHODS The radiology information database was queried for patients with PAPVR diagnosed on chest(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 the relative frequency of radiographic findings in symptomatic children with vascular rings. MATERIALS AND METHODS Preoperative chest radiographs in 41 children (mean age, 21 months) with surgically proved vascular rings were retrospectively analyzed. There were 41 frontal and 39 lateral radiographs. Lateral views were evaluated for(More)
Thin-section, three-dimensional (3D) gradient-echo magnetic resonance imaging of the coronary arteries was performed without and with retrospective respiratory gating in 12 healthy volunteers and one patient. In all examinations, results were improved with gating. In five of seven volunteer examinations, coronary artery delineation on images reconstructed(More)
