【摘要】：目的探讨CEUS参数成像在颈部淋巴结不同病变中的诊断价值。方法 111例诊断为颈部肿大淋巴结的患者均接受CEUS参数成像。根据病理结果将患者分为反应性增生组、结核组、转移组及淋巴瘤组,比较4组灌注时相(动脉相灌注、动脉相及实质相灌注)与灌注均匀度(均匀灌注、不均匀灌注)。根据病理结果将反应性增生组与结核组合并为良性组、转移组与淋巴瘤组合并为恶性组;以动脉相灌注为良性,动脉相及实质相灌注为恶性,比较2组参数成像与病理结果的一致性。结果 4组灌注时相与灌注均匀度差异均有统计学意义(P均0.05),其中反应性增生组与转移组、淋巴瘤组,结核组与转移组灌注时相比较差异均有统计学意义(P均0.008);反应性增生组与结核组、转移瘤组,淋巴瘤组与结核组、转移组灌注均匀度比较差异均有统计学意义(P均0.008)。良性组与恶性组CEUS参数成像的灌注时相比较差异有统计学意义(P0.05),灌注均匀度比较差异无统计学意义(P0.05)。CEUS参数成像诊断的良、恶性淋巴结与病理结果的一致性尚可。结论 CEUS参数成像可为常规超声难以判定性质的淋巴结诊断提供有价值的诊断信息。
[Abstract]:Objective to evaluate the diagnostic value of CEUs parameter imaging in different lesions of cervical lymph nodes. Methods 111 patients with cervical lymph nodes were examined by CEUs. According to the pathological results, the patients were divided into reactive hyperplasia group, tuberculosis group, metastatic group and lymphoma group. The perfusion phase (arterial phase perfusion, arterial phase and parenchymal phase perfusion) and perfusion uniformity (uniform perfusion, uneven perfusion) were compared among the four groups. According to the pathological results, the reactive hyperplasia group was combined with tuberculosis as benign group, metastasis group was combined with lymphoma group and malignant group, arterial perfusion was benign, arterial phase and parenchymal phase perfusion was malignant, To compare the consistency of parameter imaging and pathological results in two groups. Results there were significant differences in phase and perfusion uniformity among the four groups (P 0.05), including reactive hyperplasia group, metastasis group, lymphoma group. There were significant differences in perfusion uniformity between the reactive hyperplasia group and the tuberculosis group, the metastatic tumor group, the lymphoma group and the metastatic group (all P 0.008). There was significant difference in perfusion time between benign group and malignant group (P0.05). There was no significant difference in perfusion uniformity between benign group and malignant group (P0.05). Conclusion CEUs parameter imaging can provide valuable diagnostic information for lymph node diagnosis which is difficult to determine by conventional ultrasound.
