Intraobserver and interobserver variability were calculated for the measurement of cerebral artery pulsatility indices by five observers who made two recordings on each of 12 stable preterm infants. Variations in pulsatility indices of up to 0.21 were found; no measurement was below 0.55.
由五名观察者对12名稳定的早产儿中的每一名进行两次记录,以计算脑动脉搏动指数测量中的观察者内和观察者间变异性。发现搏动指数的变化高达0.21;没有测量值低于0.55。
