摘　　要：目的探讨多层螺旋CT(MSCT)超薄层扫描小间隔层面重建对周围性肺癌的诊断价值。方法选取2018年2月至2021年2月间西安医学院附属宝鸡医院收治的80例非小细胞肺癌患者,病理诊断为周围型肺癌55例患者纳入周围组,病理诊断为中央型肺癌的25例患者纳入中央组。所有患者都给予MSCT超薄层扫描小间隔层面重建,记录CT征象与病灶形态,判断诊断价值。结果周围组的性别、年龄、病理类型、体质量指数及组织学分化与中央组比较,差异无统计学意义(P> 0.05)。周围组的CT毛刺征、凹陷征、空泡征和分叶征等发生率显著低于中央组,差异均有统计学意义(均P <0.05)。周围组的CT病灶形态学分型多为Ⅰ型与Ⅱ型,与中央组对比,差异有统计学意义(P <0.05)。周围组的肿瘤直径、壁厚和含气腔隙大小显著低于中央组,差异有统计学意义(P <0.05)。CT诊断为中央型肺癌23例,周围型肺癌57例,CT鉴别诊断中央型肺癌与周围型肺癌的敏感性与特异性分别为92.0%和98.2%。结论 MSCT超薄层扫描小间隔层面重建能清晰显示周围性肺癌的CT征象与病灶形态,鉴别诊断的敏感性与特异性高,有很高的应用价值。Objective To investigate the diagnostic value of multislice spiral computed tomography( MSCT) ultrathin layer scanning with small reconstruction interval for peripheral lung cancer. Methods From February 2018 to February 2021,80 patients with non-small cell lung cancer( NSCLC) were selected at Baoji Hospital Affiliated to Xi’an Medical College. Fifty-five patients who were pathologically diagnosed with peripheral lung cancer were included in a peripheral lung cancer group and 25 patients who were pathologically diagnosed with central type lung cancer were included in a central type lung cancer group. All patients received MSCT ultrathin layer scanning with small reconstruction interval. The signs and lesion morphology on CT were recorded,and the diagnostic value was analyzed. Results There were no significant differences in gender,age,pathological type,body mass index,histological differentiation between the two groups( P > 0. 05). The incidence of signs of burr,depression,vacuole and lobulation on CT was significantly lower in the peripheral lung cancer group than in the central type lung cancer group( all P < 0. 05).The morphological classification of lesions on CT were mostly type I and type II in the peripheral lung cancer group,and the difference were statistically significant compared with the central type lung cancer group( all P < 0. 05). The lesion size,wall thickness and gas-bearing cavity size were significantly lower in the peripheral lung cancer group than in the central type lung cancer group( all P < 0. 05). Twenty-three patients were diagnosed with central type lung cancer and 57 patients were diagnosed with peripheral lung cancer on CT scan. The sensitivity and specificity of CT for the diagnosis of central lung cancer and peripheral lung cancer were 92. 0% and 98. 2%,respectively. Conclusion The MSCT ultrathin layer scanning with small reconstruction interval can clearly show the signs and lesion morphology of peripheral lung cancer. The sensitivity and specificity of differential diagnosis ar
