Objective: To evaluate the clinical capability of ventilation-perfusion (V-P) scintigraphy and spiral ct angiography (SCTA) in the diagnosis of pulmonary embolism (PE).
目的：比较通气蛐灌注(V - P)显像和螺旋ct血管成像(SCTA)对肺栓塞(PE)诊断的临床价值。
An altered level of consciousness indicates the need for immediate reevaluation of the patient's oxygenation, ventilation, and perfusion status.
意识水平的改变意味着要对患者的氧和作用，通气和灌注状况进行重新评估。
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。
