Abstract:
Objective To investigate the diagnosis of diffusion-weighted imaging (DWI) in cervical lymph nodes lesions.Methods Twenty patients with metastatic lymph node,10 patients with tuberculosis lymph node and 10 volunteers were underwent both conventional MRI and DWI,and the ADC values of lymph nodes' solid components were measured.The difference of ADC values between three kinds of lymph nodes were analyzed.Results ADC values of metastatic lymph nodes was (0.842 ± 0.156) × 10-3 mm2/s,ADC values of tuberculosis lymph nodes was (1.249 ± 0.142) × 10-3 mm2/s,and ADC values of normal lymph nodes was (1.291 ± 0.176) × 10-3 mm2/s.There was significant difference between ADC values of metastatic lymph nodes and with the two later kinds of lymph nodes (P＜ 0.01),and no difference in the two later kinds of lymph nodes (P ＞ 0.05).Conclusion ADC values with features of conventional MR is helpful for differentiate metastatic lymph node,tuberculosis lymph node and normal lymph nodes.
