摘　　要：目的探讨PACS翻转窗宽和窗位床旁胸片在经外周静脉置入中心静脉导管(Peripherally Inserted Central Venous Catheters,PICC)末端定位中的价值。方法由2名放射科医生对84例PICC患者的床旁胸部平片,在PACS上分别用常规窗宽、窗位和翻转窗宽、窗位两种方法进行观察,并比较两种方法的差异。同时以PICC置管后1周内的胸部CT为标准,评价翻转窗宽、窗位床旁胸部平片对PICC末端定位的准确性。结果翻转窗宽、窗位法对PICC末端的观察效果优于常规窗宽、窗位法,一致性检验的统计学结果(P<0.001,Kappa<0.4);翻转窗宽、窗位床旁胸部平片对PICC末端的定位结果和胸部CT扫描的定位结果一致性好(P<0.001,Kappa>0.75)。结论 PACS翻转窗宽、窗位床旁胸片在PICC末端定位中有较大的应用价值。Objective To evaluate the value of bedside chest radiograph of PACS flip window width&window level in localizing the end of peripherally inserted central venous catheters(PICC).Methods With the methods of conventional window width&window level and flip window width&window level,2radiologists evaluated the images of84patients with PICC bedside chest radiography by conventional and flip window width&window methods.At the same time,the accuracy of PICC’s end localization was evaluated one week after placing of PICC by using chest CT as standard.Results The effect of flip window width&window level bedside chest radiography was better than that of conventional method in PICC’s end positioning(P<0.001,Kappa<0.4).Besides,the consistency of fip window width&window level bedside chest radiography to the chest CT was high(P<0.001,Kappa>0.75).Conclusion The flip window width&window level of the bedside chest radiograph on PACS has great value in PICC’s end localization.
