Abstract：Objective To explore the application low dose scanning technology of MSCT guided percutaneous lung punc-ture biopsy in clinic .Methods 56 patients with indications were randomly divided into two groups ,i .e .,the conventional dose group (CDG) and low dose group (LDG) ,with 28 cases in each group .The percutaneous lung puncture biopsy was performed under the guidance of 16 row spiral CT .Results The success rate for puncture was 100% and the correct rate was 96 .4% .Pathological examination confirmed that there were 49 cases of malignant tumor ,2 cases of benign tumor , and 2 cases of false negative lesion .The X-ray radiation dose of patients in Low dose group was considerably decreased than that in patients in the conventional dose group ,accounting for 25% ~30% of doses in normal group .Conclusion Low dose scanning technique does not affect the MSCT guided percutaneous lung puncture biopsy and greatly reduces the radiation dose ,thereby being worth popularizing in clinic .
