螺旋CT在胃癌淋巴结转移中的临床价值

The clinic value of metastatic lymph nodes in gastric cancer with spiral computed tomography

目的分析人胃癌淋巴结转移的螺旋CT的影像学特征。方法对经手术病理证实的42例胃癌淋巴结的螺旋CT影像特征进行回顾性分析,并与术后病理结果进行对照研究。结果螺旋CT共检出淋巴结326个,其中阳性淋巴结有224个(阳性率68.7%)。长径≥8 mm淋巴结阳性率达76.1%。结论螺旋CT影像学特征对判断胃癌淋巴结转移有重要意义,根据淋巴结长径≥8 mm,结合淋巴结平扫CT值≥25 Hu为诊断阳性淋巴结标准,将大大提高对胃癌淋巴结转移的诊断水平。

Objective To enclosure the characteristics of SCT in the diagnosis of lymph nodes metastases in gastric cancer, it provide the evidence for clinicians. Methods The characteristics of SCT of metastatic lymph nodes in 42 gastric cancer patients compared with operation and pathology and were retrospectively analyzed. Results A total amount of positive 229 lymph nodes were detected by SCT and confirmed by pathology in with metastasis or without metastasis patients. The positive rate of lymph nodes more than or equal to 8mm with diameter was 76.1%. Conclu- sion The reference of diameter more than or equal to 8 ram, combining with the application of attenuation values more than or equal to 25Hu in plain scan can improve the diagnosis for lymph node metastasis in gastric cancer.
