目的:观察并对比周围型肺癌患者的X线片与CT检查结果,对两种检查方式进行评定,并为今后临床治疗提供可靠依据。方法:选取中山大学附属东华医院自2015年2月至2016年3月收治的48例周围型肺癌患者,所有患者均分别进行X线片与CT检查,分析并对比2种检查结果。结果:CT检查在支气管气象征与空泡征、血管凝聚征、胸膜凹陷征、肺门与纵隔淋巴结肿大以及后壁空洞等的诊断率上明显优于采取X线片检查,差异具有统计学意义(P<0.05)。结论:采取X线检查具有操作方便、检查费用较低等优点,尤其适用于初步诊断以及普查阶段时期的周围型肺癌患者;采取CT检查具有密度分辨率高、空间分辨率低、检查过程中辐射大、扫描时间长以及费用较高等特征,因此,适用于进一步确诊周围型肺癌患者的检查中。而为了能够对周围型肺癌患者提供更准确的诊断依据,建议临床中将两种检查手段进行合理结合,以便为后续治疗提供更可靠的依据。
OBJECTIVE: To observe and compare the results of X-ray and CT in patients with peripheral lung cancer, evaluate the two methods of examination, and provide a reliable basis for future clinical treatment. Methods: Forty-eight patients with peripheral lung cancer were enrolled from Donghua Hospital Affiliated to Sun Yat-sen University from February 2015 to March 2016. All the patients were examined by X-ray and CT respectively. The results of two tests were analyzed and compared. Results: The diagnostic accuracy of CT examination in bronchial air sign and vacuole sign, vascular condensation sign, pleural indentation, hilar and mediastinal lymph node enlargement, and posterior wall cavity were significantly better than that of X-ray examination, the difference was statistically significant Significance (P <0.05). Conclusion: The X-ray examination has the advantages of convenient operation, low cost of examination and so on. It is especially suitable for patients with peripheral lung cancer during the initial diagnosis and census stage. CT scan has the advantages of high density resolution, low spatial resolution, Large, long scan time and high cost, so it is suitable for the further diagnosis of patients with peripheral lung cancer. In order to provide a more accurate diagnosis basis for patients with peripheral lung cancer, it is suggested that the two methods should be combined rationally in order to provide a more reliable basis for follow-up treatment.
