摘要
目的探析CT定量分析肺动脉栓塞病情严重等级的准确性。方法回顾性分析经临床及CTPA证实的APE患者,均行CT检查,总结患者CT征象、明确PE患者病情严重等级并以临床及CTPA结果为基准计算分级准确率。结果 PE患者平扫征象以局限性密度增高、局限性密度减低、肺动脉异常扩张、两肺后部胸膜下斑片、索条影等为主,大部分患者栓塞区碘基值显著低于对照区,病情严重程度分级准确性为93.0%(40/43)。结论平扫结合相关病史可及时确定PE发生风险,CT定量分析可明确患者病情严重程度,准确性高,CT检查在PE中应用临床价值显著。
Objective To explore the accuracy of CT quantitative analysis of the severity level of pulmonary embolism. Methods Patients with APE confirmed by clinic and CTPA were retrospectively analyzed. All underwent CT examination. The CT findings of patients were summarized and the severity level of PE was defned. The clinical and CTPA results were taken as the standard to calcnlate the accuracy rate of classification.Results The findings of plain scan of PE patients mainly were increase of local density, decrease of local density, abnormal dilatation of pulmonary arteries, posterior subpleural patches in the two lungs and strip shadows, etc.. The iodo-values of embolization areas were significantly lower than those of the control areas in most patients and the accuracy of classification ofseverity level was 93.0% （40/43）.Conclusion Plain scan combined with related history can timely determine the risk ofPE. CT quantitative analysis can determine the severity of the patient＇s pathogenetic condition and the accuracy is high. The clinical value of CT examination in PE is significant.
