BACKGROUND Admission rates among patients presenting to emergency departments with possible acute coronary syndromes are high, although for most of these patients, the symptoms are ultimately found not to have a cardiac cause. Coronary computed tomographic angiography (CCTA) has a very high negative predictive value for the detection of coronary disease,(More)
PURPOSE To compare the incidence and distribution of coronary artery disease after left-sided versus right-sided irradiation in patients treated with breast conservation for early-stage breast cancer who subsequently underwent cardiac stress testing and/or catheterization for cardiovascular symptoms. PATIENTS AND METHODS The medical records of 961 stage(More)
PURPOSE To evaluate the safety and feasibility of 3-T magnetic resonance (MR) imaging of the brain in patients with implanted cardiac pacemakers (PMs) by using a transmit-receive head coil. MATERIALS AND METHODS The study protocol was approved by the institutional review board. Signed informed consent was obtained from all subjects. In vitro testing at 3(More)
BACKGROUND AND OBJECTIVE Fibroblast growth factor 23 (FGF-23), a regulator of phosphorus metabolism, is a risk marker in CKD. FGF-23 has been associated with coronary arterial calcification (CAC), but it is not known whether FGF-23 predicts CAC progression in CKD. The aim of this study was to evaluate the association of FGF-23 with CAC progression in(More)
OBJECTIVES Our aim was to establish and evaluate a strategy for safe performance of magnetic resonance imaging (MRI) at 1.5-T in patients with implantable cardioverter-defibrillators (ICDs). BACKGROUND Expanding indications for ICD placement and MRI becoming the imaging modality of choice for many indications has created a growing demand for MRI in ICD(More)
There is a significant risk of complication following endovascular abdominal repair (EVAR), including endoleak, graft translocation, thrombosis, and infection. Surveillance imaging is important for detecting EVAR complication. Surveillance modalities include conventional X-ray, computed tomography, magnetic resonance imaging, ultrasound, and conventional(More)
Diagnostic imaging for aortic dissection has dramatically changed in recent years. Previously, imaging consisted of conventional X-ray radiography, followed by invasive catheter angiography. Now imaging of dissection is performed primarily with multidetector CT, and to a lesser extent, with ultrasound and MRI. Catheter angiography is used primarily as a(More)
There is an established sex difference in cardiovascular disease among pre-menopausal women and age-matched men, with men having greater susceptibility to cardiovascular and coronary artery disease. Cardiovascular calcification may be linked to the atherosclerotic process and resulting disease, but the sex difference regarding coronary artery disease(More)
BACKGROUND The purpose of the present study was to evaluate a strategy for safe performance of extrathoracic magnetic resonance imaging (MRI) in non-pacemaker-dependent patients with cardiac pacemakers. METHODS AND RESULTS Inclusion criteria were presence of a cardiac pacemaker and urgent clinical need for an MRI examination. Pacemaker-dependent patients(More)
