Coronary CT angiography for acute chest pain.
Each year, more than 6 million people in the United States go to emergency departments because of acute chest pain. Some of them have coronary artery disease, but most have diseases that are unrelated to the heart or they have no discernible physiological conditions. The vast majority will undergo various diagnostic tests, and many will be held for observation and may be admitted to the hospita...
متن کاملLeft Ventricular Diastolic Dysfunction Assessment with Dual-Source CT
PURPOSE To assess the impact of left ventricular (LV) diastolic dysfunction on left atrial (LA) phasic volume and function using dual-source CT (DSCT) and to find a viable alternative prognostic parameter of CT for LV diastolic dysfunction through quantitative evaluation of LA phasic volume and function in patients with LV diastolic dysfunction. MATERIALS AND METHODS Seventy-seven patients we...
متن کاملSingle-source chest-abdomen-pelvis cancer staging on a third generation dual-source CT system: comparison of automated tube potential selection to second generation dual-source CT
BACKGROUND Evaluation of latest generation automated attenuation-based tube potential selection (ATPS) impact on image quality and radiation dose in contrast-enhanced chest-abdomen-pelvis computed tomography examinations for gynaecologic cancer staging. METHODS This IRB approved single-centre, observer-blinded retrospective study with a waiver for informed consent included a total of 100 pati...
متن کاملDual-energy CT in the Chest
Dual-energy CT (DECT) is accomplished by near simultaneous imaging at two energy levels, typically 80 kV and 140 kV, using scanners that either employ rapid kV switching or have two orthogonal sets of X-ray tunes and detectors mounted in the gantry. Attenuation properties differ at the two energy levels, which allow the DECT to differentiate and quantify certain substances such as water, calciu...
متن کاملChest pain: a clinical assessment.
Chest pain is one of the most common presentations in emergency medicine. The initial evaluation should always consider life-threatening causes such as aortic dissection, pulmonary embolism, pneumothorax, pneumomediastinum, pericarditis, and esophageal perforation. Radiographic imaging is performed in tandem with the initial clinical assessment and stabilization of the patient. Radiologic findi...
