Abstract:
Objective To evaluate the value of multi-slice spiral computed tomography (CT) for diagnosing acute pulmonary 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 diagnostic 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 detected 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 promotion.
