Abstract: Objective To compare the two methods of Color Doppler Ultrasonography and Multi-slice Computed Tomography scans in the diagnosis of cervical lymph node tuberculosis. Methods Forty patients diagnosed with cervical lymph node tuberculosis which confirmed by pathology from January 2014 to December 2016 in Shenzhen Center for Chronic Disease Control and Shenzhen third people's hospital were selected as the research objects. And the patients were both diagnosed with Color Doppler Ultrasonography and Multi-slice Computed Tomography scans at the same time. All patients' imaging features were retrospectively analyzed. Accuracy rate of cervical lymph node tuberculosis and imaging findings of the two methods were compared. The sensitivity, concordance rate and kappa value of the two methods were calculated. Results In 40 patients, 27 cases with cervical lymph node tuberculosis were diagnosed by the Color Doppler Ultrasonography, which accounted for 67.5% of all patient; and 28 cases were confirmed by Multi-slice Computed Tomography scans, which accounted for 70.0%. The difference of two methods showed no statistical significance（P﹥0.05). The accuracy rate of the two approaches combined method was 90.0%. Conclusion Color Doppler Ultrasonography and Multi-slice Computed Tomography scans show distinguishable characteristics in the detection of cervical lymph node tuberculosis. Contrast-enhanced CT scanning has higher accuracy than Color Doppler Ultrasonography. Ultrasounography combined with enhanced CT scan can improve the accuracy of diagnosis of cervical lymph node tuberculosis obviously.
