肺灌注断层显像和平面显像对肺栓塞诊断的价值研究
[摘要] 目的:评价肺灌注断层显像对肺栓塞(PE)的诊断价值。方法:对76例确诊为PE的患者进行肺灌注断层和平面显像,次日行肺通气显像,显像结果和CT肺动脉造影(CTPA)进行对比分析。结果:在76例PE患者中,肺灌注断层显像阳性72例,检出率为94.7%;肺灌注平面显像阳性64例,检出率为84.2%,两种方法PE检出率差异有统计学意义(P<0.05)。76例患者中,CTPA显示受累肺段为329个,肺灌注断层显像示314个肺段阳性,肺灌注断层显像与CTPA的符合率为95.4%;肺灌注平面显像示261个肺段阳性,两者符合率为79.3%,两符合率比较,差异有高度统计学意义(P<0.01)。结论:肺灌注断层显像能显著提高对PE的诊断率,可作为诊断PE的常规筛查方法。

[Abstract] Objective: To evaluate the clinical value of lung perfusion tomography in the diagnosis of pulmonary embolism (PE). Methods: Lung perfusion tomography and planar imaging were done in 76 patients with planar perfusion imaging of PE. The results were compared with those of spiral CT pulmonary arteriography (CTPA). Results: Among all the 76 patients with lung perfusion tomography and planar imaging, the detection rates of PE were 94.7% (72 cases) and 84.2% (64 cases) respectively. There was a significant difference between the two methods (P<0.05). There were 329 abnormal segments in the 76 patients with CTPA results. The lung perfusion tomography were 314 abnormal segments, with a 9...
