放射性核素肺显象是一种方便、有效、无损伤的检查方法。它以观察两侧肺脏的形态、血流分布变化为特点,通过核素示踪原理,获取肺脏生理某些方面的信息。有时当胸部X线照片不能显示时,校素显象能较早地反映肺血流方面的改变,有助于某些肺部疾病的诊断和鉴别。实践表明,如能与其它检查配合应用,可获得更好的临床效果。肺显象根据所用显象剂的特性和引入人体的方式
Radionuclide lung imaging is a convenient, effective, non-invasive method of examination. It observes both sides of the lung morphology, changes in blood flow distribution is characterized by nuclide tracing principle, access to some aspects of lung physiology information. Sometimes, when the chest radiography can not be displayed, the stereographic imaging can reflect earlier changes in pulmonary blood flow, contribute to the diagnosis and identification of some lung diseases. Practice shows that, if used in conjunction with other tests, get better clinical results. Lung imaging is based on the characteristics of the developer used and the way it is introduced into the body
