Radionuclide angiocardiography is a useful method in the evaluation of patients with congenital heart disease, safely and nontraumatically. Physiologic variables such as transit times, cardiac output, left ventricular ejection fraction, stroke volume, end-diastolic volume can be measured accurately with this technique. An important application of radionuclide angiocardiography in children with congenital heart disease is in the detection, localization and quantification (pulmonary to systemic flow ratio) of intracardiac shunts and shunts between the great vessels. This technique has been found useful in the evaluation of the newborn infant with cyanosis, the patient with a cardiac murmur and the patient who has had cardiovascular surgery. Newer mobile gamma camera-computer systems permit the performance of radionuclide angiocardiography in several ill premature and newborn infants and patients during the early postoperative period. Specially designed magnifying collimators and the development of ultrashort-lived radionuclides should result in an overall improvement in the diagnostic capabilities of this technique and in a further reduction in the radiation dose.
放射性核素心血管造影术是评估先天性心脏病患者的一种有用方法,安全且无创。通过该技术可以准确测量诸如通过时间、心输出量、左心室射血分数、每搏输出量、舒张末期容积等生理变量。放射性核素心血管造影术在先天性心脏病患儿中的一个重要应用是检测、定位和定量(肺循环与体循环血流比)心内分流以及大血管之间的分流。已发现该技术在评估发绀型新生儿、有心脏杂音的患者以及接受过心血管手术的患者中很有用。更新的移动伽马相机 - 计算机系统允许对一些患病的早产儿、新生儿以及术后早期的患者进行放射性核素心血管造影术。专门设计的放大准直器和超短寿命放射性核素的开发应会使该技术的诊断能力得到全面提高,并进一步降低辐射剂量。
