BACKGROUND Noncontrast cardiac computed tomography allows calculation of coronary artery calcium score (CACS) and measurement of epicardial adipose tissue (EATv) and intrathoracic fat (ITFv) volumes. It is unclear whether fat volume information contributes to risk stratification. METHODS AND RESULTS Cardiac computed tomography was performed in 760(More)
UNLABELLED The purpose of this study was to determine whether stress myocardial perfusion (SPECT) optimized with stress-only (SO) imaging is comparable to cardiac CT angiography (CTA) for evaluating patients with acute chest pain (ACP). METHODS This was a prospective randomized observational study in 598 ACP patients who underwent CTA versus SPECT. The(More)
From the Department of Internal Medicine, The Methodist Hospital, Houston, Texas. Manuscript received July 5, 2011; accepted July 15, 2011. A75-year-old female patient presented to our hospital with worsening shortness of breath 2 months after undergoing a coronary artery bypass graft procedure. Chest x-ray showed marked elevation of the left hemidiaphragm,(More)
Clonal abnormalities are identified by standard cytogenetic analysis of bone marrow cells in 40–50% of individuals with acquired idiopathic sideroblastic anemia/refractory anemia with ringed sideroblasts, a distinctive hematologic illness which is also classified as a form of myelodysplasia. Certain recurring chromosomal abnormalities, including 5q-, 7q-,(More)

Background Graft dysfunction after lung transplantation is typically attributable to infection or rejection. In the absence of these entities, structural cardiovascular (CV) abnormalities need to be sought. At our center this evaluation typically includes a myriad of diagnostic tests: echocardiography, chest computed tomographic angiography, nuclear(More)
Iatrogenic aortic dissection during percutaneous coronary intervention is a rare but serious complication. Both conservative and surgical approaches have been proposed as management strategies. We describe a case of an 87-year-old female who presented with an acute coronary syndrome complicated by the development of an ascending aortic dissection during(More)
BACKGROUND It is unknown whether axial non-gated CT can distinguish World Health Organization Group 2 pulmonary hypertension (pulmonary hypertension due to left heart disease) from non-Group 2 pulmonary hypertension. OBJECTIVE The study was performed to identity imaging parameters in non-gated chest CT that differentiate Group 2 from non-Group 2 pulmonary(More)
A 77 year-old male presented to our institution for evaluation of lower extremity edema. An inferior vena cava filter (IVC) was placed 8 years earlier due to the presence of unilateral deep vein thrombosis (DVT). Duplex ultrasound revealed chronic bilateral DVT of the lower extremities. Physical examination revealed grossly dilated superficial veins of the(More)
