The large amount of information from dynamic 99Tcm-DTPA lung can be simplified and rendered easily interpretable by the use of functional images. Eight such images have been devised: a maximum count image, a minimum count image, a time of maximum count image, a time of minimum count image, percentage maximum change image, a T50 image, a standard error image and a correlation coefficient image. These images enable the distribution of aerosol after inhalation, the reliability of the calculated T50 value and movement artefacts to be easily identified. They also allow rapid assessment of the distribution of T50 values in the lungs which may be particularly useful in segmental lung disease.
动态99锝-二乙三胺五乙酸肺显像所产生的大量信息,通过使用功能图像可得到简化并易于解读。现已设计出8种这样的图像:最大计数图像、最小计数图像、最大计数时间图像、最小计数时间图像、最大变化百分比图像、T50图像、标准误差图像和相关系数图像。这些图像能够使吸入后气溶胶的分布、计算所得T50值的可靠性以及运动伪影易于识别。它们还能快速评估肺部T50值的分布情况,这在节段性肺部疾病中可能特别有用。
