本文旨在探讨放射性核素法在评价肺心病中的价值,选择一组慢阻肺病人用~(201)Tl(铊)心肌灌注单光子发射计算机断层摄影(SPECT),定量评估右心室肥大,并用多门平衡放射性核素~(81m)Kr(氪)心室摄影法测定右室射血分数(RVEF),以观察上二项指标与肺动脉压的关系,以及右室肥厚和右室功能间的相互关系。受试者为15例处于稳定期和代偿期的慢阻肺病人,根据~(201)Tl 心肌SPECT 影象,测
This paper aims to explore the value of radionuclide in the evaluation of pulmonary heart disease, select a group of COPD patients with ~ (201) Tl (thallium) myocardial perfusion single photon emission computed tomography (SPECT) quantitative assessment of right ventricular hypertrophy, The right ventricular ejection fraction (RVEF) was measured by multi-gate balanced radionuclide ~ (81m) Kr (krypton) ventriculography to observe the relationship between the above two indexes and pulmonary arterial pressure and the relationship between right ventricular hypertrophy and right ventricular function Interrelationship. The subjects were 15 COPD patients in stable and compensatory phase. According to ~ (201) Tl myocardial SPECT images,
