[摘要] 目的 对多排螺旋CT技术在诊断和鉴别早期周围期小肺癌中的临床应用效果进行分析。 方法 方便选取2016年7月—2017年7月该院收治的早期周围型小肺癌111例患者的临床资料进行回顾性分析。对所有患者行多排螺旋CT技术扫描，对患者的影像学表现情况进行仔细观察，判定多排螺旋CT技术在诊断及鉴别早期周围型小肺癌的价值。 结果 经多排螺旋CT技术诊断，发现患者病灶多在左肺中集中，病灶大小集中在9～15 mm，結节内部表现为毛玻璃样密度小泡征，且呈密度不够均匀的小颗粒堆积状，患者病灶边缘具有较深的分叶。另外，18例患者病灶周围可见胸膜边缘呈磨玻璃样晕影，35例患者病灶周围可见有线影，45例患者为胸膜凹陷征，13例患者为支气管血管聚集征。45例患者病灶为均匀强化，66例患者病灶为不均匀强化，病灶时间密度曲线缓慢升高。 结论 在诊断和鉴别早期周围型小肺癌中采用多排螺旋CT可准确探查患者病灶情况，为临床诊断提供具体依据，可作为临床诊断鉴别早期周围型小肺癌的影像诊断首选方式。

[Abstract] Objective This paper tries to analyze the clinical effect of multislice spiral CT in the diagnosis and differential identifications of small early-stage lung cancer. Methods The clinical data of 111 patients with early-stage small lung cancer who were admitted to this hospital from July 2016 to July 2017 were convenient analyzed retrospectively. All patients were undergone multi-slice spiral CT scan，and the patient's imaging findings were carefully observed to judge the multi-detector row CT in the diagnosis and early diagnosis of peripheral small lung cancer value. Results After multi-slice CT diagnosis， it was found that most of the lesions were concentrated in the left lung. The size of the lesions was concentrated in 9 to 15 mm. The nodules showed small froth-like vesicles inside the nodules， and the edge of the lesion has deeper lobes. In addition， 18 cases of lesions around the pleural effusion showed a glass-like vignetting， 35 cases of lesions seen around the cable， 45 cases of pleural indentation， and 13 cases of bronchial blood vessels gathered signs. In 45 cases， the lesions were uniformly strengthened， the lesions in 66 cases were unevenly enhanced， and the time-density curve of the lesions increased slowly. Conclusion Multislice spiral CT can accurately detect the lesion in patients with early small peripheral lung cancer and it provide a specific basis for clinical diagnosis. It can be used as the first choice of imaging diagnosis in early diagnosis of peripheral small lung cancer.

早期周围型小肺癌的病灶部位在肺段支气管下段，在疾病早期时临床上发现较为困难。近年来，随着城市污染的不断加重，人们患有周围型小肺癌的概率也越来越高，患病后患者的生活质量得到降低，也使得社会及家庭承担的负担加重。……
