【摘要】：目的探讨CT肺血管造影(CTPA)和肺血管灌注成像(DEPI)对肺栓塞的诊断价值。方法回顾性分析31例经临床确诊为肺动脉栓塞患者的临床资料。所有患者均在双能量模式下行肺动脉造影检查,同时获得两组数据,即CTPA图像数据和DEPI图像数据。将CTPA图像数据设为A1组,DEPI图像数据设为A2组,分析A1组图像显示的肺动脉内有无血栓及栓塞程度;分析A2组图像显示的肺灌注缺损及缺损程度,并分析CTPA和DEPI结果的相关性。结果 A1组、A2组图像在显示肺动脉干(Ⅰ级)、肺叶肺动脉(Ⅱ级)的血栓及栓塞程度方面,差异无统计学意义(P0.05);在显示肺段肺动脉(Ⅲ级)及亚段肺动脉(Ⅳ级)方面有显著差异(P0.05)。结论 CTPA和DEPI关于肺栓塞的诊断指标有一定差异性,结合两种检查手段可提高肺栓塞的诊断准确性。
[Abstract]:Objective to evaluate the diagnostic value of CT pulmonary angiography (CTPA) and pulmonary perfusion imaging (DEPI) in pulmonary embolism. Methods the clinical data of 31 patients with pulmonary embolism were retrospectively analyzed. Two groups of data, CTPA image data and DEPI image data, were obtained in all patients under dual energy mode pulmonary angiography. The CTPA image data were divided into A 1 group and A 2 group to analyze the degree of thrombus and embolism in pulmonary artery of A 1 group, pulmonary perfusion defect and defect degree in A 2 group, and the correlation between CTPA and DEPI results. Results in group A1, group A _ 2 showed the degree of thrombus and embolism in pulmonary trunk (grade 鈪，
