A transmission-emission method for the absolute quantitation of Tc-99m in the lungs with a computerized gamma camera is described. The method requires no measurements of the linear attenuation coefficients of the lung and chest wall, or of their thickness. It yields results of acceptable accuracy for everyday clinical use and offers the great advantage of avoiding the use of a phantom. The method could be extended for the absolute quantification of Tc-99m agents in soft tissue and bone with errors of less than 10%.
描述了一种使用计算机伽马相机对肺中Tc-99m进行绝对定量的发射-透射方法。该方法无需测量肺和胸壁的线性衰减系数或其厚度。它产生的结果对于日常临床使用具有可接受的准确性,并具有避免使用体模的巨大优势。该方法可扩展用于软组织和骨骼中Tc-99m制剂的绝对定量,误差小于10%。
