Quantitative evaluation of cardiac ventricular and atrial chamber sizes, ventricular function, and left ventricular mass is important for prognosis and management. The most common methods for quantitative evaluation have been echocardiography and cardiac magnetic resonance imaging. Recently, multidetector cardiac computed tomography (CCT) technology has evolved to permit imaging of cardiac structure, function, volume, and mass. Potential advantages of CCT over existing methods include 3-dimensional volumetric assessment of cardiac chambers which are free of geometric assumptions and the ability to obtain true, on-axis imaging planes with double-oblique orientations.
定量评估心室和心房大小、心室功能以及左心室质量对于预后和治疗管理至关重要。定量评估最常用的方法是超声心动图和心脏磁共振成像。近年来，多排心脏计算机断层扫描（CCT）技术不断发展，能够对心脏结构、功能、容积和质量进行成像。与现有方法相比，CCT的潜在优势包括对心腔进行三维容积评估，无需几何假设，以及能够获得具有双斜位取向的真实轴上成像平面。
