摘要目的确定先天性心脏病(CHD)三维(3D)全心影像检查时哪个静息时相(舒张期或收缩期)对评价或测量心脏结构效果最佳。材料与方法研究由学院审查委员会批准,并取得病人的知情同意书。50例儿童(男26例,女24例)接受3D双时相全心成像。分析心脏结构的对比噪声比(CNR)与影像质量
Abstract Objective To determine which resting phase (diastolic or systolic) in congenital heart disease (CHD) three-dimensional (3D) total cardiac imaging is best for evaluating or measuring cardiac structures. Material and methodological studies were approved by the College Board of Review and informed consent was obtained from patients. Fifty children (26 males and 24 females) underwent 3D bi-phase heart imaging. Analysis of cardiac structure contrast to noise ratio (CNR) and image quality
