摘要
Abstract
Objective To discuss the effectiveness of application of CTPA (CT Pulmonary Angiography) and DEPI (Dual Energy Perfusion Imaging) in the diagnosis of pulmonary embolism. Methods A retrospective analysis of clinical data of 31 clinically-diagnosed patients with pulmonary embolism was made. All patients underwent pulmonary artery angiography under the mode of dual energy so as to obtain two groups of data (CTPA data and DEPI data). CTPA data and DEPI data were taken as Group A1 and Group A2 respectively. Analysis of A1 Group could display whether the pulmonary artery thrombus existed and the degree of embolization; while, analysis of Group A2 could determine the pulmonary perfusion defects, and the degree of defects. The correlation between CTPA and DEPI was analyzed. Results Images of A1 and A2 Group had no statistically signiifcant difference in displaying of embolus and thrombotic degree of pulmonary stem (Grade I) and lobar artery (Grade II) (P>0.05). While, statistically signiifcant difference was seen in displaying of pulmonary segmental artery (Grade III) and pulmonary sub-segment artery (Grade IV) (P<0.05). Conclusion CTPA and DEPI showed different indicators in diagnosis of pulmonary embolism, combination of these two methods could improve the accuracy in diagnosis of the disease.关键词
