摘要
目的探讨CT增强扫描对周围型肺癌淋巴结转移的临床诊断价值。方法选取我院2013年1月-2015年12月入院治疗的周围型肺癌患者69例作为研究对象,均进行CT平扫和CT增强扫描,观察病灶的大小、形态、位置,并结合有无淋巴结转移瘤的特征对其进行分析。结果 69例周围型肺癌患者中发生淋巴结转移的有42例(约占60.8%),其中小细胞淋巴结20例(约占28.9%),腺癌淋巴结16例(约占23.2%),鳞癌淋巴结6例(约占8.7%),而未发生淋巴结转移的有2 7例(约占39.1%),CT增强扫描未检测出病灶的有1例(约占1.5%);周围型肺癌患者中,转移性淋巴结的CT净增强程度略低于非转移性淋巴结,差异具有统计学意义(P<0.05);周围型肺癌患者的肺窗与纵隔窗胸部CT图以及动脉期、静脉期和延迟期CT增强扫描图,能清楚地显示病灶大小与位置。结论CT增强扫描具有较高的检出率,提高了对病灶的定性能力,为肺癌的早期发现与治疗提供了科学的理论依据。对于早期症状不明显的周围型肺癌淋巴转移瘤,CT增强扫描应用更为广泛,具有较高的临床价值。
Objective To evaluate the clinical diagnostic value of enhanced CT scanning of peripheral lung cancer lymph node metastasis. Methods A hospital in March 2014- December 2015 patients with peripheral lung cancer in 69 patients admitted to hospital as the research object, underwent CT scan and CT scan, observe the lesion size, shape, location, and presence or absence of binding lymph node metastases feature analyze. Results 69 cases of peripheral lung cancer patients with lymph node metastasis in 42 cases (approximately 60.8%), of which 20 cases of small celt lymph node (about 28.9%), 16 cases of adenocarcinoma lymph node (about 23.2%), squamous cell carcinoma 6 cases of lymph node (about 8.7%), without lymph node metastasis 27 cases (approximately 39.1%), CT enhanced scan lesions not detected one case (about 1.5%), peripheral lung cancer patients, net degree of enhancement CT was slightly lower than non-metastatic lymph node metastatic lymph nodes, the difference was statistically significant (P〈0.05), peripheral lung cancer patients with lung window and mediastinal window view and chest CT arterial phase, venous phase and delayed phase CT enhanced scan can clearly draw the lesion size and location. Conclusion Contrast-enhanced CT scan has a high detection rate, improved lesion characterization capabilities for early lung cancer detection and treatment provide a scientific theory. For the early symptoms of peripheral hmg cancer lymph nude metastases, CT enhanced scan applied more widely, with a high clinical value.
