Abstract

Quantitative radionuclide angiocardiography (QRAC) was performed with and without deconvolution analysis (DA) in 87 children with various heart disorders. QRAC shunt quantitation was possible without DA in 70% of the cases and with DA in 95%. Among 21 patients with prolonged bolus injections, quantitation of the shunt was possible in 52% of the cases without DA an in all cases with DA. Correlation between oximetry and QRAC with DA was better than between oximetry and QRAC without DA. It is concluded that QRAC with DA is a more reliable, noninvasive means for detection and quantitation of left-to-right cardiac shunts than QRAC without DA.

摘要

对87例患有各种心脏疾病的儿童进行了定量放射性核素心血管造影（QRAC），分别采用了和未采用去卷积分析（DA）两种方法。在70%的病例中，不采用DA时QRAC分流定量是可行的，而采用DA时这一比例为95%。在21例推注时间延长的患者中，不采用DA时52%的病例能够进行分流定量，而采用DA时所有病例均可进行分流定量。采用DA的QRAC与血氧饱和度测定之间的相关性优于未采用DA的QRAC与血氧饱和度测定之间的相关性。得出的结论是，与未采用DA的QRAC相比，采用DA的QRAC是一种更可靠的、用于检测和定量左向右心脏分流的非侵入性方法。
