肺栓塞与肺梗死的影像学检查的实验研究

Experimental Study on Imaging Examination of Pulmonary Embolism and Infarction

目的 比较研究不同影像学检查方法对肺栓塞、肺梗死的诊断价值。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。结果 X线平片是一种初步的检查方法 ;核素灌注扫描安全、简单 ,病变检出率高 ;增强螺旋CT是目前较理想的诊断、复查及追随方法 ;血管造影在病变检出等方面无明显优势。结论 考虑以“X线平片→核素灌注扫描→增强螺旋CT→血管造影”

Objective To compare the diagnosis value of different methods of imaging examination on pulmonary embolism and infarction. Methods The pig experimental models of pulmonary embolism and infarction were examined by X ray, ventilation perfusion scanning, helical CT, angiography. Results X ray was a initial examinatorial method; Ventilation perfusion scanning was safe and simple, the recognizable rate of disease was high; Helical CT was a more satisfied method; Angiography was not superior to helical CT. Conclusion 'X ray→ventilation perfusion scanning→helical CT→angiography' is the best examination program.
