摘要
目的:探讨低剂量螺旋CT对孤立性肺结节良恶性病变的鉴别诊断价值。方法:对常规剂量(255mA)螺旋CT发现有孤立性肺结节的42例患者,再行一次低剂量(70mA)螺旋CT扫描,比较两种剂量螺旋CT扫描孤立性肺结节在形态学特征、定性诊断方面是否有差异。结果:低剂量组在孤立性肺结节的形态学特征、定性诊断方面与常规剂量组比较,差异无统计学意义(P>0.05)。结论:低剂量螺旋CT扫描和常规剂量螺旋CT扫描对孤立性肺结节良恶性病变的鉴别诊断无差异,而低剂量螺旋CT扫描具有明显减少X射线辐射量的优势,对于青少年、孕妇、免疫力低下患者等X射线敏感人群更有其特殊的意义。
Objective:To investigate the value of low-dose CT in the differential diagnosis of benign and malignant lesions of solitary pulmonary nodules.Methods:42patients with solitary pulmonary nodules were found with conventional dose(255mA)spiral CT,and a low-dose(70mA)spiral CT scan was performed again,and the differences were compared between the two kinds dose of spiral CT scanning solitary pulmonary nodules in the morphological characteristics and qualitative diagnosis.Results:The morphological characteristics and qualitative diagnosis of solitary pulmonary nodules in low-dose group were compared with that of conventional dose group,and the difference was not statistically significant(P〉0.05).Conclusion:The differential diagnosis of benign and malignant lesions of solitary pulmonary nodules is not different from low-dose spiral CT scanning and conventional dose spiral CT scanning,and low-dose spiral CT scanning has obvious advantages in reducing the radiation dose of X-ray,and For X-ray sensitive people such as young people,pregnant women,patients with low immunity have special significance.
