Tracheal collapse is a common disease in small, middle-aged dogs, and imaging tools are essential for its diagnosis. Radiography and fluoroscopy are the main diagnostic modalities used, but their agreement in different regions is not well documented. In this study, the agreement between thoracic radiography and fluoroscopy in tracheal collapse was investigated in 29 dogs. The results showed that radiography detected a lower degree of collapsing trachea compared to fluoroscopy at the carina region ( < 0.001). However, there was no significant difference observed between the degree of collapsing trachea detected by radiography and fluoroscopy at the cervical, thoracic inlet, and intra-thoracic regions ( = 0.780, 0.537, and 0.213, respectively). The kappa statistic indicated a slight agreement at the cervical region at a 16.4% cut-off (κ = 0.20), while the other regions showed a non-agreement. In conclusion, although radiography is useful for screening, fluoroscopy was able to detect the degree of the collapsing trachea greater than radiography in the carina region. Additionally, if a collapse in the cervical region is detected by radiography, it is prone to have a positive relationship with fluoroscopy as well.
气管塌陷是小型中年犬的常见疾病，影像学检查工具对其诊断至关重要。X线摄影和荧光透视是主要的诊断方式，但它们在不同部位的一致性尚无充分记录。本研究对29只犬的气管塌陷进行了胸部X线摄影和荧光透视的一致性研究。结果显示，在隆突部位，X线摄影检测到的气管塌陷程度低于荧光透视（<0.001）。然而，在颈部、胸廓入口和胸腔内区域，X线摄影和荧光透视检测到的气管塌陷程度无显著差异（分别为=0.780、0.537和0.213）。kappa统计量表明，在颈部区域，以16.4%为截断值时存在轻微一致性（κ=0.20），而其他区域则不一致。总之，虽然X线摄影对筛查有用，但荧光透视在隆突区域检测到的气管塌陷程度大于X线摄影。此外，如果X线摄影检测到颈部区域有塌陷，其与荧光透视也可能呈正相关。
