低剂量MSCT扫描诊断周围型肺癌的临床价值

Clinical value of low-dose MSCT scan in the diagnosis of peripheral lung cancer

目的:探讨周围型肺癌诊断中低剂量多层螺旋CT(MSCT)扫描的临床价值。方法:选取疑似周围型肺癌患者198例,按照随机数表法分为低剂量组和常规剂量组各99例。低剂量组采用低剂量MSCT检查,常规剂量组采用常规剂量MSCT检查,并均以病理诊断结果为标准,比较两组诊断结果及诊断价值。结果:两组周围型肺癌的组织分型比较;两组诊断周围型肺癌的准确性、敏感性、特异性、阴性预测值及阳性预测值比较;两组的血管集束征、空泡征、胸膜凹陷征、毛刺征及肿瘤分叶征的检出率比较,差异均无统计学意义(P>0.05)。结论:低剂量MSCT诊断周围型肺癌可满足临床诊断要求,易被临床接受。

Objective:To investigate the clinical value of low-dose multi-slice spiral computed tomography(MSCT)scan in the diagnosis of peripheral lung cancer.Methods:One hundred and ninety-eight patients with suspected peripheral lung cancer were divided into a low-dose group and a routine-dose group with 99 cases each according to random number table,in which the former was given low-dose MSCT examination and the later routine-dose MSCT examination.The diagnostic results and diagnostic value were compared between the two groups by taking pathological diagnosis results as the standard.Results:There were no statistical differences between two groups in the tissue typing of peripheral lung cancer,the diagnostic accuracy,sensitivity,specificity,negative predictive value and positive predictive value and the detection rate of vessel convergence sign,vocule sign,pleural indentation sign,spicule sign and tumor lobulation sign(P>0.05).Conclusion:Low-dose MSCT for the diagnosis of peripheral lung cancer can meet the diagnostic requirements and is easily accepted by the clinic.
