摘要
目的:研究并探讨螺旋CT在胸部结节病诊断中的应用效果。方法:于2014年1月~2017年2月期间,将该阶段内我院收治的60例胸部结节病确诊患者纳入研究,所有患者均先后进行螺旋CT常规剂量扫描、螺旋CT低剂量扫描,分别作为常规剂量组、低剂量组,比较两种扫描剂量螺旋CT检查对胸部结节病的检出情况、定性诊断结果以及图像质量。结果:常规剂量组与低剂量组对胸部结节病患者的结节检出个数比较无统计学差异(P>0.05),且两种扫描剂量螺旋CT检查对各结节CT征象的检出率比较也无统计学差异(P>0.05)。在定性诊断结果中,两种扫描剂量螺旋CT检查对肺癌、肺转移瘤、炎性结节的诊断符合率比较,差异无统计学意义(P>0.0.5),且二者的定性不明比例比较也无统计学差异(P>0.05)。在图像质量方面,低剂量组的图像质量优良率为90.00%,常规剂量组的图像质量优良率则为93.33%,二者比较,差异无统计学意义(P>0.05)。结论:在胸部结节病诊断中,采用螺旋CT检查可对结节予以有效检出,对结节良恶性进行准确鉴别诊断,尤其是螺旋CT低剂量扫描,可在减少扫描剂量的同时,保证图像质量。
Objective： to study and explore the effect of spiral CT in the diagnosis of chest sarcoidosis. Methods： in from January 2014 to February 2014, during the period of 60 patients with chest sareoidosis confirmed our hospital into the study, all patients underwent conventional dose spiral CT scan and spiral CT low - dose scan, as a regular dose group, low dose group, respectively, comparing two scanning dose spiral CT examination of chest sarcoidosis detection, qualitative diag- nosis and image quality. Results ： routine dose group and low dose group of chest nodules patients nodule number detection is no statistical difference （ P 〉 0. 05 ） , and two kinds of scanning dose spiral CT examination of the nodules CT signs of detec- tion is also no statistical difference （ P 〉 0. 05 ）. In qualitative diagnosis results, two kinds of scanning dose spiral CT exami- nation of lung cancer, lung metastases, the diagnostic accordance rate of inflammatory nodules, there was no statistically sig- nificant difference （ P 〉 0. 0. 5 ） , and the qualitative unknown proportion of the two factors is also no statistical difference （ P 〉 0. 05）. In terms of image quality, the image quality of low dose group was 90. 00% , the conventional dose group of the image quality was 93.33% , the comparison, there was no statistically significant difference （P 〉 0. 05 ）. Conclusion： for diagnosis of chest sareoidosis, the spiral CT examination can effectively to nodules detection, accurate differential diagnosis of benign and malignant nodules, especially spiral CT low - dose scan, but at the same time of reducing scanning dose, ensure the quality of the image.
