多排螺旋CT在肺孤立性结节病灶诊断中的应用价值分析

The Value of Multi-Slice Spiral CT in the Diagnosis of Solitary Pulmonary Nodules

目的分析多排螺旋CT在肺孤立性结节病灶诊断中的应用价值。方法收集2016年2月-2017年7月本院诊治的肺孤立性的结节病灶90例的临床资料,所有患者均应用多排螺旋CT检查。结果于肺孤立性结节病灶90例患者中,其中恶性肺结节所占比例为60.00%,良性肺结节所占比例为40.00%,且两者于支气管充气征、胸膜凹陷征等CT征象上对比差异显(P<0.05)。多排螺旋CT在肺孤立性结节病灶的诊断准确率为99.00%;恶性肺结节者于净增强和增强峰CT值(47.84±4.67)HU和(80.24±10.50)HU均比良性肺结节高,两者差异显著,具统计意义(P<0.05)。结论对肺孤立性结节病灶患者应采用多排螺旋CT检查,有利于鉴别肺结节病灶的良、恶性,具较高推广价值。

Objective To observe and analyze the value of multi-slice spiral CT in the diagnosis of solitary pulmonary nodules. Methods The clinical data of 90 patients with solitary pulmonary nodules who had received treatment in the hospital between February 2016 and July 2017 were analyzed, and all the patients were diagnosed by multi-slice spiral CT, and the actual diagnostic value was observed. Results Among the 90 patients with solitary pulmonary nodules, patients with malignant pulmonary nodules accounted for 60.00%, benign pulmonary nodules accounted for 40.00%, with significant difference shown in air bronchogram and pleural indentation CT signs （P〈0.05）. The accuracy of multi slice spiral CT for solitary pulmonary nodule was 100.00%; net enhancement value and enhanced peak CT value in malignant pulmonary nodules were respectively （47.84±4.67） HU and （80.24±10.50） HU, both higher than those of benign pulmonary nodules, and the difference was statistically significant （P〈0.05）. Conclusion For patients with solitary pulmonary nodules, multi slice spiral CT is with higher diagnosis value and it is of significant value to be popularized in clinical application.
