Applicationvalue of multi-slice spiral CTguided lung biopsypuncture in the diferential diagnosisof benign and malignantlung lesionsGuiRunxiao.Imaging Department，Ruzhou People's Hospital，Henan4675oo，China
【Abstract】 ObjectiveTo explore the application value of multi-slice spiral CT （MSCT） guided lung biopsy punctureinthe diffrential diagnosisof benign and malignant lung lesions.MethodsSeventy-six patients with lung lesionswho visitedour hospital from July2O2Oto August2O23were includedasthestudysubjects.All patients underwent chest MSCT examination and lung biopsy guided by MSCT.The results of chest MSCT examination，the results and successrateof lung biopsy guided by MSCT，the detection of complications inthe diagnosisof benign and malignantlung lesionsbychest MSCT guided lung biopsy，and the influencing factorson theoccurrenceof postoperative complications after MSCT guided lung biopsy were analyzed.ResultsAll76 patients completed MSCT - guided lung biopsyand puncture examinations.Pathological examination after punctureconfirmed 58 cases with malignant lesionsand18 cases with benign lesions in the lungs.Another successul puncture was performed in70 cases，with a success rate of 92% . Six cases were successfully punctured twice，with a success rate of 8% .After
MSCT-guided lung biopsy，there were 5 cases with local minor bleeding，11 cases with pneumothorax，and 3cases with pulmonary infection.The detection rate of patients withcomplications aged 6O years or older was higher than thatof patientswithout complications，theaveragediameter of lesions wassmaller than that of patientswithout complications，and the distance between lesionsand thechest wallwas greater than that of patients without complications，with statistical differences （ P <0.05）.Logistic regression analysis showed that patient age，lesion diameter，and distance betweenthelesionand chestwallwere independentrisk factors for theoccurrenceof postoperative complications after MSCT-guided lung biopsy （P<0.05） .ConclusionMSCT-guided lung biopsy can effctively diferentiate benign and malignant lung lesions，improve the success rateofone-time punctureof lesions， reduce the risk of complications after puncture，be safe and reliable，and have high promotion and application value.

肺部占位性病变临床诊断难度较高，由于症状不典型且呈多样性，特别是对于肺部微小病灶，临床诊断难度较高，但因肺部恶性病变病情进展速度较快，预后较差，为改善患者预后、延长生存时间，尽早明确肺部病变良恶性诊断显得尤为重要[1，2]目前，病理学检查结果为鉴别诊断肺部病变良恶性的“金标准”，但该方法对患者造成创伤较大，部分患者接受度较低[3]。（剩余6354字）
