Abstract
Objective To explore the value of CT perfusion(CTP) in differentiating cervical lymph nodes (CLN)reactive hyper-plasia,tuberculosis and metastatic carcinoma. Methods CTP was performed in 51 patients with CLN lesions,including reactive hy-perplasia 8 cases,tuberculosis 13 cases and metastasis 30cases. The data of time-density curve(TDC)and perfusion parameters were analyzed. Results The shapes and features of time-density curve(TDC) of these three type lesions were different. The average of blood flow(BF) and blood volume(BV) of lymph nodes metastases were significantly higher than those of lymph nodes tuberculosis and reactive hyperplasia. The average of blood flow(BF) and blood volume(BV) of lymph nodes reactive hyperplasia were significantly higher those of lymph nodes tuberculosis(P<0. 05). The average of mean transit time(MTT) and permeability surface(PS) among three type CLN were not significantly different(P>0. 05). Conclusion TDC and CT perfusion parameters BF and BV were useful in differentiating cervical lymph nodes CLN)reactive hyperplasia,tuberculosis and metastatic carcinoma.关键词
