肺通气/灌注功能图像产生的方法和评价

The Generation of Lung Functional Image with Ventilation/Perfusion

介绍了一种用^99mTc-DTPA和^99mTc-MAA这两种临床常用的药物进行肺的通气/灌注显像，然后经过简单的处理，产生黑、蓝、绿、黄、红、白六种颜色的色阶，根据功能图像上局部肺组织的颜色差异。可以半定量地对肺的通气/血流情况进行评估，每个颜色的级差为20%，这种评估方法简便实用，值得探讨。

It is described that using 99mTc-DTPA and 99mTc-MAA to acquire a ventilation/perfusion ratio image of lungs from posterior. A color scale with black, blue, green, yellow, red and white was generated simply. According to the difference of regional color of tbe lungs, we can easily semid-quantitively evaluate the regional V/Q of the lungs. We conclude that this technique is very simple, but very useful for doctors to comment the fuction of the lungs.
