Diagnostic value of multi-slice spiral computed tomography for acute pulmonary embolism
Objective To evaluate the value of multi-slice spiral computed tomography(CT)for diagnosing acute pulmon-ary embolism,and to provide a reference for the precise diagnosis of acute pulmonary embolism.Methods We enrolled a total of 102 patients pathologically diagnosed with acute pulmonary embolism from January 2019 to October 2023.All the patients underwent CT scanning of central and segmental pulmonary arteries with a GE 64-slice spiral CT scanner.The dia-gnostic efficacy of multi-slice CT scans for acute pulmonary embolism was evaluated with the pathological results as the gold standard.Results Of the 102 patients pathologically diagnosed with acute pulmonary embolism,multi-slice CT de-tected 92 cases,with an accuracy of 90.20%(92/102),including 17 cases(18.48%)of embolism in left pulmonary arteries,31 cases(33.70%)of embolism in right pulmonary arteries,and 44 cases(47.82%)of embolism in both pulmonary arteries.Multi-slice CT visualized a total of 9905 pulmonary artery branches,and 304 of them(3.07%)had embolism,with the highest embolism rate in lobar arteries(43.89%).Conclusion Multi-slice spiral CT has high accuracy for diagnosing acute pulmonary embolism by directly and clearly visualizing embolism in the arteries of the lungs,which deserves clinical promo-tion.
