目的探讨螺旋CT对腹腔淋巴结病变的诊断价值及在临床治疗及预后方面的意义。方法回顾性分析我院收治的腹腔淋巴结病变患者62例的影像学资料,与手术病理结果进行对照研究。结果螺旋CT腹部增强扫描30例淋巴结转移者,诊断正确27例,漏诊3例。螺旋CT诊断腹腔淋巴结转移与否的准确率为87.09%,并发现淋巴结直径≥10mm者,病理转移的阳性率高(P<0.001)。淋巴瘤组及转移性淋巴结组的长短径、平扫CT值、增强后双期期CT值均高于炎症性肿大组,差异均有统计学意义(P<0.05)。结论治疗前使用螺旋CT增强扫描可以明确腹腔淋巴结的病变性质,有利于肿瘤分期及治疗方案的选择。
Objective To investigate the diagnostic value of spiral CT in the diagnosis of celiac lymph nodes and its significance in clinical treatment and prognosis. Methods Retrospective analysis of 62 cases of celiac lymph node lesions in our hospital imaging data, and surgical pathology results were compared. Results Thirty cases of lymph node metastasis were scans enhanced by helical CT. There were 27 cases diagnosed correctly and 3 cases missed diagnosis. The accuracy of spiral CT in diagnosing celiac lymph node metastasis was 87.09%. The positive rate of lymph node metastasis was higher (P <0.001). Lymphoma group and metastatic lymph node length and short diameter, CT scan value, double phase CT value were higher than the inflammatory enlargement group, the difference was statistically significant (P <0.05). Conclusion The enhancement of the lesions of the abdominal lymph nodes can be confirmed by the enhanced spiral CT before treatment, which is helpful for the selection of the tumor staging and treatment options.
