Tracheal diameter can be assessed from a thoracic radiograph, with assessment of tracheal diameter in dogs based on ratios between tracheal diameter and a skeletal measurement. Reference intervals are not, however, available for the cat. Tracheal narrowing may cause significant clinical problems, although tracheal hypoplasia in dogs may be clinically silent, and is rarely reported in cats (both mesati- and brachycephalic). The tracheal diameter and trachea:thoracic inlet and trachea:rib ratios were calculated for populations of domestic shorthair (DSH) (n = 68) and Persian (n = 40) cats. This gave reference intervals for radiographic tracheal measurements in these breeds. It is proposed that the tracheal diameter in a normal DSH cat should be 18% of the diameter of the thoracic inlet, and compared to 20% in Persian cats.
气管直径可通过胸部X光片进行评估，犬类气管直径的评估基于气管直径与骨骼测量值之间的比率。然而，猫的参考区间尚无定论。气管狭窄可能会导致严重的临床问题，尽管犬类气管发育不全在临床上可能没有症状，且在猫（包括中头型和短头型）中很少有报道。对家养短毛猫（DSH）（n = 68）和波斯猫（n = 40）群体计算了气管直径以及气管与胸廓入口和气管与肋骨的比率。这得出了这些品种猫的X光气管测量参考区间。建议正常家养短毛猫的气管直径应为胸廓入口直径的18%，而波斯猫为20%。
