Abstract:
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,P<0.05), and the sensitivity of observation group was higher than that of control group, and both the diagnostic specificity of the two groups were 100%. For embolism of different part, the accuracy of observation group was higher than that of control group. And for the comparison of left multiple between the two groups, the difference were significant (x2=4.168,P<0.05). While for the comparisons of single, bilateral and multiple for right side, the differences between the two groups were no significant (x2=2.355, x2=0.917,x2=2.912,P>0.05). 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,P<0.05). While the comparisons of pericardial effusion, pleural effusion and pulmonary artery hypertension, the differences of them between the two groups were no significant (x2=3.214,x2=3.733,x2=3.281;P>0.05).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.
