Parametric imaging of CEUS for blood perfusion in cervical lymphadenopathy / 中国医学影像技术

ABSTRACT

Objective To explore the diagnostic value of parametric imaging of CEUS in different cervical lymphatic diseases.Methods One hundred eleven patients diagnosed with cervical lymphadenopathy were included.All of the patients underwent parametric imaging of CEUS.According to the pathological results,all patients were divided into reactive hyperplasia group,tuberculosis group,metastasis group and lymphoma group.The features of perfusion phases (perfusion during the artery phase,or perfusion during the artery and parenchymal phase) and perfusion uniformity (homogeneous perfusion or heterogeneous perfusion) were compared among four groups.According to the pathological results,the reactive hyperplasia group and the tuberculosis group were merged into a benign group,and the metastasis group and the lymphoma group were merged into a malignant group.Then,the artery perfusion phase was regarded as benign,and the artery and parenchymal perfusion phase was regarded as malignant.The consistency between parametric imaging of CEUS and the pathological results was compared in two groups.Results The difference of perfusion phase and perfusion uniformity within the four groups had a statistical significance (all P＜0.05).The differences of perfusion phase between the reactive hyperplasia group and the metastasis group,the reactive hyperplasia group and the lymphoma group,the tuberculosis group and the metastasis group were statistical significant respectively (all P＜0.008).The differences of perfusion uniformity between the reactive hyperplasia group and the tuberculosis group,the reactive hyperplasia group and the lymphoma group,the lymphoma group and the tuberculosis group,the lymphoma group and the metastasis group were statistical significant respectively (all P＜0.008).The perfusion phase between the benign group and the malignant group had a statistical significance (P＜0.005),but the perfusion uniformity had no statistical significance in two groups.The consistency was good between the parametric imaging and the pathological results.Conclusion The parametric imaging of CEUS can offer valuable diagnostic information for the cervical lymph nodes underdetermined by conventional ultrasound.
