Qualitative phase analysis of radionuclide angiocardiograms has been applied in pediatric nuclear cardiology. The technique involves the static and dynamic display of phase images. Qualitative phase analysis is valuable in two major images: (a) delineating borders of adjacent cardiac chambers such as the AV valve planes and the borders of the right ventricular outflow tract, for accurate selection of regions of interest, and (b) identifying and evaluating patterns of asynchronous contraction. Radionuclide angiography with phase analysis is a safe, noninvasive, and easily repeatable assessment of cardiac function well suited to patients with congenital heart disease.
放射性核素心血管造影的定性相位分析已应用于儿科核心脏病学。该技术涉及相位图像的静态和动态显示。定性相位分析在两个主要方面具有价值：(a) 描绘相邻心腔的边界，如房室瓣平面和右心室流出道的边界，以便准确选择感兴趣区域；(b) 识别和评估异步收缩模式。带有相位分析的放射性核素血管造影是一种安全、无创且易于重复的心脏功能评估方法，非常适合先天性心脏病患者。
