Objective To investigate the value of spiral CT dynamic enhanced scan diagnosis of gland tumors and its strengthening characteristics. Methods 98 cases of parotid tumors(total 109 lesions) confirmed pathologically in the hospital seven years were retrospectively studied,all patients underwent spiral CT scan and enhanced examination,analysis and evaluate the CT morphology and distribution of observed lesions multi-phase dynamic enhanced liquidity feature(enhanced mode and degree of enhancement). Results 98 cases of parotid tumors by surgery pathology diagnosis of benign 84 cases(85.7%),including 56 cases of pleomorphic adenoma,adenolymphoma 24 cases,4 cases of basal cell carcinoma;14 cases of malignant tumors(14.3%),including 5cases of mucoepidermoid carcinoma,adenoid cystic carcinoma 4 cases,4 cases of acinar cell carcinoma,lymphoepithelial carcinoma 1case;CT scan shows CT values of various types of tumors of the parotid gland without significant difference(P 0.05);Enhanced features:Pleomorphic adenoma characterized by progressive strengthening,adenolymphoma liter downhill speed performance enhancement pattern,basal cell carcinoma showed rapid rise continued to strengthen,and malignant tumor characterized by gradual and delay to strengthen,adenolymphoma arterial phase CT was significantly higher than other types of tumors,the difference was statistically significant(P0.05);Lesion distribution location,edge,aggressive,it was also a significant differences. Conclusion observing parotid gland tumor lesions in different periods enhanced scanning strengthening characteristics by spiral CT and the combination of different parts of the lesion,shape,edge,aggressive,etc.,further can improve the accuracy of qualitative diagnosis of parotid gland tumors,and provide more scientific,objective basis for clinical reasonable treatment.
