Abstract:
OBJECTIVE:To explore the value of flow imaging with contrast-enhanced ultrasound for residual neck lymph nodes in nasopharyngeal carcinoma after radiotherapy.
METHODS:Blood flow imaging of 50 residual cervical lymph nodes in 36 patients with nasopharyngeal carcinoma after radiotherapy was observed and compared by color doppler ultrasound and contrast-enhanced ultrasonography.
RESULTS:In the 50 remaining lymph nodes in the neck, 40 blood flow signals were increased, 10 did not significant change by contrast-enhanced ultrasonography. The blood flow in residual lymph nodes by contrast-enhanced ultrasonography was richer than that by color doppler ultrasound. There was a significant difference in the blood flow signals between contrast-enhanced ultrasonography and color doppler ultrasound (chi(2)=49.172, P<0.01).
CONCLUSION:Contrast-enhanced ultrasonography can help blood flow imaging of the residual lymph nodes in nasopharyngeal carcinoma after radiotherapy, which may provide the imaging basis for clinical diagnosis and treatment.
