In the evaluation of pericardial disease, computed tomography (CT) and magnetic resonance (MR) imaging traditionally have been used as adjuncts to echocardiography. However, CT and MR imaging are particularly useful as sensitive and noninvasive methods for evaluating loculated or hemorrhagic pericardial effusion, constrictive pericarditis, and pericardial(More)
OBJECTIVE The objectives of our study were to determine the accuracy of single-detector helical CT (including coronal and sagittal reconstructions) for the diagnosis of traumatic diaphragmatic injury, establish measurements for the thickness of the normal diaphragmatic crus, and describe an additional sign of diaphragmatic injury: active arterial(More)
Relapse of prostate cancer after androgen ablation therapy is hormone-refractory, with continued tumor growth being dependent on the androgen receptor (AR). E2F-1, a regulator of cell proliferation and viability, reportedly plays a role in the development of hormone-refractory prostate cancer. Thymoquinone is a component of Nigella sativa, an herb used for(More)
PURPOSE To evaluate the usefulness of electron-beam computed tomography (CT) for identification of coronary artery stenoses. MATERIALS AND METHODS Coronary angiography and contrast material-enhanced, electrocardiographically triggered electron-beam CT of the heart were performed in 23 patients. With axial CT images and axial maximum intensity projection(More)
Imaging plays an essential role in the evaluation of malignant pleural mesothelioma (MPM). Computed tomography is the primary imaging modality used for the diagnosis and staging of MPM. Magnetic resonance (MR) imaging and, more recently, positron emission tomography (PET) have emerged as modalities that can provide additional important diagnostic and(More)
PURPOSE To compare the sensitivity and positive predictive value of magnetic resonance (MR) imaging and technetium 99m 2-methoxyisobutyl-isonitrile (MIBI) scintigraphy for the detection of hyperfunctioning parathyroid tissue when used alone and in combination in a large patient population with recurrent or persistent hyperparathyroidism (HPT). MATERIALS(More)
The diagnosis of patients with acute chest pain remains a challenging problem. There are approximately 6 million chest pain related emergency department (ED) visits annually in the US alone [1]. Approximately 5.3% of all ED patients are seen because of chest pain and reported admission rates are between 30% and 72% for these patients [2]. Only 15–25% of(More)
