冠状动脉CT血管造影(CCTA)是一个无创的检测工具,它可用于鉴别心肌缺血和冠状动脉斑块。CCTA经常被误解为一个独立的冠状动脉疾病(CAD)诊断方法,事实上,它是现有多种检查手段的一个补充,这些检查办法如运动心电图、铊扫描、核灌注和心导管插入(或称有创冠脉造影)。严重的缺乏协调、对辐射的担心以及费用不能报销等因素一直阻碍着CCTA市场的增长。典型的心脏CT血管造影是通过向冠状动 Coronary CT angiography (CCTA) is a non-invasive detection tool that can be used to identify myocardial ischemia and coronary plaque. CCTA is often misinterpreted as a stand-alone method of diagnosing coronary artery disease (CAD). In fact, CCTA is a supplement to many existing tests such as electrocardiogram, thallium scan, nuclear perfusion, and cardiac catheterization Called invasive coronary angiography). Serious lack of coordination, radiation concerns and costs can not be reimbursed and other factors have hindered the CCTA market growth. A typical cardiac CT angiogram is through the coronaries
