目的确定在不损失诊断质量或肾功能精确定量的前提下儿科病人肾动态显像所需99锝m(99Tcm)巯乙酰三甘氨酸(mercaptoacetyltriglycerine,MAG3)的最少剂量并调查适当减少噪声是否有助于减少所需的最少剂量。
Objectives To determine the minimum dose of 99 technetium m (99Tcm) mercaptoacetyltriglycerine (MAG3) required for renal dynamic imaging in pediatric patients without loss of diagnostic quality or accurate quantitation of renal function and to investigate whether appropriate reduction of noise contributes Reduce the minimum dose required.
