目的 探讨日本大耳白兔气管和主支气管解剖径线CT测量的窗位与窗宽选择,为气道支架动物实验奠定基础.方法 多层螺旋CT扫描30只成年健康日本大耳白兔的胸部,分别常规肺窗、纵隔窗和特殊的脂肪窗测量气管胸段前后径,左右径、左右主支气管前后径.比较不同窗宽窗位下气管壁显示以及测量数据与解剖数据之间的差异.结果 肺窗气管壁均清晰显示,但测量的结果偏小;纵隔窗气管壁显示模糊,测量的结果偏大;而脂肪窗气管壁显示均匀,测量的数据比较接近实际气管直径的解剖参数.结论 多层螺旋CT测定日本大耳白兔气管左右径和前后径应选择脂肪窗为佳.有助于为人相关气管和支气管定制气道支架确定最佳的窗宽和窗位.
目的 探討日本大耳白兔氣管和主支氣管解剖徑線CT測量的窗位與窗寬選擇,為氣道支架動物實驗奠定基礎.方法 多層螺鏇CT掃描30隻成年健康日本大耳白兔的胸部,分彆常規肺窗、縱隔窗和特殊的脂肪窗測量氣管胸段前後徑,左右徑、左右主支氣管前後徑.比較不同窗寬窗位下氣管壁顯示以及測量數據與解剖數據之間的差異.結果 肺窗氣管壁均清晰顯示,但測量的結果偏小;縱隔窗氣管壁顯示模糊,測量的結果偏大;而脂肪窗氣管壁顯示均勻,測量的數據比較接近實際氣管直徑的解剖參數.結論 多層螺鏇CT測定日本大耳白兔氣管左右徑和前後徑應選擇脂肪窗為佳.有助于為人相關氣管和支氣管定製氣道支架確定最佳的窗寬和窗位.

Objective To investigate the optimal window width and window level for measuring the airway dimensions with spiral CT scan in Japanese white big-ear rabbits so as to lay the foundation for airway stenting in animal experiments. Methods Multi-slice spiral CT scanning of cervico-thoracic region was performed in 30 healthy adult Japanese white big-ear rabbits, the anteroposterior and transversal diameter of the thoracic trachea, the anteroposterior diameter of the right and left bronchus were measured with lung window, mediastinum window and special fat window separately. The revealing rate of the tracheal wall and the measuring results in different windows and levels were recorded and compared with the anatomical data. The differences of the relevant data were statistically analyzed. Results With lung window, the tracheal wall was well demonstrated, but the relevant data were smaller than that with mediastinum window. With mediastinum window, the data were bigger and the tracheal wall border appeared blurred. The results obtained with fat window were close to the actual anatomical data. Conclusion For accurately measuring the anteroposterior and transversal diameter of the thoracic trachea in Japanese white big-ear rabbits with multi-slice spiral CT scan, fat window should be adopted, which is helpful for the preparation of tracheal and bronchial stents.
