【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。更多还原

【Abstract】 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, 2 radiologists evaluated the images of 84 patients 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.更多还原
