RESUMO
Objective:To investigate the comparison of diagnostic value between multi-slice spiral CT (MSCT) and MR pulmonary angiographies in the diagnosis of acute pulmonary embolism.Methods: 86 patients with acute pulmonary embolism who underwent imaging examination were randomly divided into control group (43 cases) and observation group (43 cases) according to random number table method. The patients in the control group were analyzed with MSCT for enhanced scan under pulmonary angiography. The patients in the observation group were analyzed with MR for pulmonary artery imaging and pulmonary embolism. These results were compared depended on above data.Results: The differences of sensitivity and Youden index between control group and observation group were statistically significant (x2=10.052,x2=10.052,P0.05). For the diagnosis of various indirect symptom, the accuracy of observation group was higher than control group. For the comparison of diagnostic accuracy of pulmonary segments infarct between the two groups, the difference of them was significant (x2=5.630,P0.05).Conclusion: For patients with acute pulmonary embolism, the diagnosis by using MR imaging technology has series advantages, such as convenient operation and higher diagnostic accuracy, and it can accurately determine the severe degree of the disease.
