Ventilation perfusion scanning was safe and simple, the recognizable rate of disease was high; 核素灌注扫描安全、简单,病变检出率高;
Pulmonary interstitial fibrosis is a kind of pulmonary interstitial disease which manifested by progressing dyspnea, asthma, short breath, dry cough and characterized by limiting ventilation perfusion ratio, hypoxemia, chronic progressing diffused pulmonary interstitial fibrosis. 肺间质纤维化是以进行性呼吸困难、喘息、气短、干咳、喘憋为临床表现、以限制性通气功能障碍、低氧血症、慢性进行性弥漫性肺间质纤维化为特点的肺间质性疾病。
Objective To assess the value of radionuclide pulmonary ventilation perfusion imaging, helical CT pulmonary angiography ( HCTPA ) and D dimer assay in the diagnosis of pulmonary embolism ( PE ). 目的评价核素肺通气灌注(VQ)显像、螺旋CT肺动脉造影(HCTPA)及血浆D二聚体在诊断肺动脉血栓中的作用。
Methods The pig experimental models of pulmonary embolism and infarction were examined by X ray, ventilation perfusion scanning, helical CT, angiography. 方法以小型猪为肺栓塞、肺梗死实验动物模型,进行X线平片、核素灌注扫描、螺旋CT、血管造影检查。
Clinical value of radionuclide pulmonary ventilation / perfusion ratio imaging in pulmonary embolism 肺通气/灌注比值显像在肺血栓栓塞症诊断中的价值
