【摘要】：目的探討CT肺血管造影(CTPA)和肺血管灌注成像(DEPI)對肺栓塞的診斷價值。方法回顧性分析31例經(jīng)臨床確診為肺動脈栓塞患者的臨床資料。所有患者均在雙能量模式下行肺動脈造影檢查,同時獲得兩組數(shù)據(jù),即CTPA圖像數(shù)據(jù)和DEPI圖像數(shù)據(jù)。將CTPA圖像數(shù)據(jù)設(shè)為A1組,DEPI圖像數(shù)據(jù)設(shè)為A2組,分析A1組圖像顯示的肺動脈內(nèi)有無血栓及栓塞程度;分析A2組圖像顯示的肺灌注缺損及缺損程度,并分析CTPA和DEPI結(jié)果的相關(guān)性。結(jié)果 A1組、A2組圖像在顯示肺動脈干(Ⅰ級)、肺葉肺動脈(Ⅱ級)的血栓及栓塞程度方面,差異無統(tǒng)計學(xué)意義(P0.05);在顯示肺段肺動脈(Ⅲ級)及亞段肺動脈(Ⅳ級)方面有顯著差異(P0.05)。結(jié)論 CTPA和DEPI關(guān)于肺栓塞的診斷指標(biāo)有一定差異性,結(jié)合兩種檢查手段可提高肺栓塞的診斷準(zhǔn)確性。
[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，
