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.

肺部占位性病變臨床診斷難度較高，由于癥狀不典型且呈多樣性，特別是對于肺部微小病灶，臨床診斷難度較高，但因肺部惡性病變病情進展速度較快，預后較差，為改善患者預后、延長生存時間，盡早明確肺部病變良惡性診斷顯得尤為重要[1，2]目前，病理學檢查結果為鑒別診斷肺部病變良惡性的“金標準”，但該方法對患者造成創(chuàng)傷較大，部分患者接受度較低[3]。（剩余6354字）
