Abstract:
Purpose:To discuss the relationship between the extent of red pseudocolor of pseudocolor CT image and MVD in lung carcinoma.Materials and Methods: The CT angiography was performed by using 16-slices spiral CT in 25 cases with pulmonary carcinoma,proved by pathology.Pseudocolor VR of tumor lesions of pulmonary carcinoma was performed.The immunohistochemical test of MVD of tumor lesion of pulmonary carcinoma was performed in 25 cases.The relation between the extent of red color on pseudo color VR and MVD of tumor lesion of pulmonary carcinoma were analyzed.Results: The extents of red pseudocolor of tumor lesion on VR pseudocolor Imaging were divided to four types: heavy ( n = 5 ),moderate ( n - 8 ),light (n = 9 ),no color( n = 3 ).The add CT values of tumor lesion after enhanced CT were 26.32 ±9.17Hu in 13 cases with heavy or moderate group,10.87 ±4.257Hu in 12 cases with light or no red color group.The numbers of MVD of tumor lesion of pulmonary carcinoma were 57 ±6.43 in 13 cases with heavy or moderate group,19 ±5.29 in 12 cases with light or no red color group.The numbers of MVD of pulmonary carcinoma had statistical significant between heavy or moderate group and light or no red color group.Conclusion:It has a significantly direct correlation between the extent of red pseudocolor of tumor lesion on pseudocolor image and MVD of tumor lesion in pulmonary carcinoma.
