In order to evaluate the clinical usefulness of radionuclide methods measuring the magnitude of left-to-right cardiac shunts, a comparison has been made of the results obtained using these procedures with those estimated by cardiac catheterization. Seventy children in whom the presence or absence of a shunt had been established, were studied. Two methods for radionuclide shunt quantitation, the pulmonary to systemic blood flow ratio (Qp/Qs) of Maltz and Treves and their modified C2/C1, were evaluated. The former was found to be superior and showed a high correlation of shunt size with the catheter results. With attention to the performance of the investigation and in the data analysis, good discrimination can be achieved between normal patients and those with shunts. Because of the atraumatic nature of the investigation, it is concluded that the procedure is of value in the diagnosis of a cardiac murmur, the assessment of postoperative patients and the follow-up of patients known to have a small shunt.
为了评估放射性核素方法测量心脏左向右分流大小的临床实用性，已将使用这些程序获得的结果与通过心导管检查估计的结果进行了比较。研究了70名已确定有无分流的儿童。评估了两种放射性核素分流定量方法，即Maltz和Treves的肺循环与体循环血流量比（Qp/Qs）及其改良的C2/C1。发现前者更具优势，并且分流大小与导管检查结果具有高度相关性。关注检查的执行情况和数据分析，可以在正常患者和有分流的患者之间实现良好的区分。由于该检查具有无创性，得出的结论是该程序在心脏杂音的诊断、术后患者的评估以及已知有小分流患者的随访中具有价值。
