Abstract
Objective To evaluate the differential diagnosis value of multi-slice spiral CT in lymphoma and metastatic lymph nodes on mediastinum.Methods The CT findings of 42 cases of lymph nodes on mediastinum(lymphoma 21 cases,metastatic lymph nodes 21 cases)were observed by the size,shape,CT value,enhancement style and distribution of lymph nodes.Results The plain scan CT value of lymphoma was higher than that of metastatic lymph nodes(t=3.880,P﹤0.01),andthe diameter was also larger(t=4.323,P﹤0.01).Lymphoma was homogeneous enhancement(13/21,61.9%).The metastatic lymph nodes were peripheral enhancement(12/21,57.1%)more.Conclusions MSCT is quite helpful for the differential diagnosis of lymphoma and metastatic lymph nodes on mediastinum. Key words: Lymphoma; Lymph node metastasis; Multi-slice spiral CT
