Breast Radiation Protection in Coronary Angiography
Introduction: Coronary angiography (CA) is an interventional diagnostic procedure to assess cardiovascular disease. CA is performed using dedicated fluoroscopic systems equipped with either flat detector or image intensifier. There is an increase in the number of CA annually. Reducing the radiation exposure in the CA is essential, especially due to high fluoroscopy time. In ord...
متن کاملStaff dose assessment from coronary angiography
Background: Interventional cardiology procedures such as coronary angiography (CA) and percutaneous transluminal coronary angiography (PTCA) has been increased recent years. The purpose of this study was to measurement of effective dose to cardiology staffs who operate near the patient and are exposed to non-uniform radiation field due to patient scattered radiation. Materials and Methods: This...
متن کاملCan coronary computed tomography angiography replace invasive angiography? Coronary computed tomography angiography cannot replace invasive angiography.
O ne million patients undergo invasive coronary angiogra-phy (CA) in the United States every year. 1 In view of its invasive nature and related costs, noninvasive imaging of coronary imaging has the theoretical appeal to improve comfort for patients, reduce cost, and refine patient selection to limit invasive procedures to patients requiring treatment for ischemic coronary artery disease (CAD)....
متن کاملCORONARY ANGIOGRAPHY Potential intrinsic error of noninvasive coronary angiography
Purpose. With current noninvasive techniques compromises have to be accepted for coronary imaging, e.g., partial coverage of the coronary artery tree. The aim of the study was to estimate the potential intrinsic error of partial coverage from a database of invasive angiograms. Methods and Results. The localization and severity of coronary artery stenoses and, if percutaneous coronary interventi...
متن کاملCT coronary angiography vs. invasive coronary angiography in CHD
SCIENTIFIC BACKGROUND Various diagnostic tests including conventional invasive coronary angiography and non-invasive computed tomography (CT) coronary angiography are used in the diagnosis of coronary heart disease (CHD). RESEARCH QUESTIONS The present report aims to evaluate the clinical efficacy, diagnostic accuracy, prognostic value cost-effectiveness as well as the ethical, social and leg...
