Abstract
Objective:To investigate the value of low‐dose CT in the differential diagnosis of benign and malignant lesions of solitary pulmonary nodules .Methods :42 patients with solitary pulmonary nodules were found with conventional dose(255 mA) spiral CT ,and a low‐dose(70 mA) 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 mor‐phological characteristics and qualitative diagnosis .Results :The morphological characteristics and qualitative diagno‐sis 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 signifi‐cance .关键词
