目的探讨超声对腹部淋巴结肿大的诊断价值。方法对72例腹部淋巴结肿大患者分别进行超声和磁共振检查,以最终诊断为标准比较上述两种方法的准确性。结果超声检查转移性淋巴结准确率95.35%,原发性淋巴瘤准确率100.00%,炎性淋巴结肿大准确率95.24%,淋巴结结核准确率100.00%,总准确率为95.83%。磁共振检查转移性淋巴结准确率79.07%,原发性淋巴瘤准确率80.00%,炎性淋巴结肿大准确率80.95%,淋巴结结核准确率100.00%,总准确率为80.56%。超声检查准确率高于磁共振检查,差异有统计学意义(χ2=8.704,P=0.0045<0.05)。结论超声检查可综合反应腹部淋巴结多重信息,有利于不同疾病导致腹部淋巴结肿大的鉴别诊断。
Objective To investigate the diagnostic value of ultrasound in the diagnosis of abdominal lymph nodes. Methods Totally 72 patients with abdominal lymph node enlargement were examined by ultrasound and MRI respectively. The final diagnosis was used as a standard to compare the accuracy of the above two methods. Results The accuracy of ultrasonography was 95.35% in metastatic lymph nodes, 100.00% in primary lymphoma, 95.24% in inflammatory lymph nodes, 100.00% in lymph nodes and 95.83% in total. MRI accuracy of metastatic lymph nodes 79.07%, 80.00% accuracy of primary lymphoma, inflammatory lymph node enlargement accuracy 80.95%, lymph node tuberculosis accuracy 100.00%, the total accuracy of 80.56%. The accuracy of ultrasound examination was higher than that of MRI examination, the difference was statistically significant (χ2 = 8.704, P = 0.0045 <0.05). Conclusion Ultrasound examination can comprehensively reflect the multiple information of abdominal lymph nodes, which is beneficial to the differential diagnosis of abdominal ailments with different diseases.
