目的探讨周围性小肺癌的薄层螺旋CT图像特点及临床价值。方法 54例周围性小肺癌患者,随机分为研究组和对照组,各27例,研究组采用薄层螺旋CT扫描方式,对照组采用常规CT扫描方式,对比两组患者的CT扫描和诊断结果。结果研究组的诊断准确率为88.89%,对照组的诊断准确率为51.85%,两组结果对比差异具有统计学意义(P<0.05)。结论薄层螺旋CT扫描方式对于诊断周围性小肺癌患者有着较高的诊断准确率,能够更加具体清晰的将患者的内部结构特征等准确的呈现,有助于做出对周围性小肺癌疾病的正确诊断结果 ,从而做好提早治疗工作。 Objective To investigate the characteristics and clinical value of thin-slice spiral CT in peripheral small lung cancer. Methods Fifty-four patients with peripheral small lung cancer were randomly divided into study group and control group, with 27 cases in each group. The study group was treated with thin-slice spiral CT scan and the control group was treated with conventional CT scan. CT scan and diagnosis results were compared between the two groups . Results The diagnostic accuracy of the study group was 88.89%, and the diagnostic accuracy rate of the control group was 51.85%. The difference between the two groups was statistically significant (P <0.05). Conclusion The thin-slice spiral CT scan has high diagnostic accuracy for the diagnosis of peripheral small lung cancer patients, and can accurately present the internal structural features of the patients accurately and help to make a diagnosis of peripheral small lung cancer Correct diagnosis of the results, so early treatment work.
