“…Tracheal length was reported to be proportional to a range of BM 0.27 to BM 0.34 7 .

“…7 In a computed tomography (CT) study in dogs, there was a strong correlation between the inner transverse and vertical diameters of the trachea and the cross-sectional area of the lumen to bodyweight, except at the level of the intrathoracic trachea. 9 It is generally recommended to make respiratory thoracic radiographs at full inspiration. However, additional expiratory radiographs are required to evaluate the effect of respiration on tracheal diameter or for evaluation of restrictive lung disease.…”

Radiographic measurement of tracheal dimensions in the horse may be useful in evaluating upper and lower respiratory tract conditions due to the gradient of pressure changes between these areas. Lateral radiographs of the trachea of 15 normal sedated Thoroughbred horses were made at inspiration and expiration and magnification-corrected mean airway heights measured were, respectively: larynx: 5.89 and 5.86 cm; trachea at the third cervical vertebra (C3): 4.17 and 4.04cm; at the fifth cervical vertebra (C5): 3.62 and 3.59 cm; at the first thoracic vertebra (T1): 3.4 and 3.23cm; and carina: 3.85 and 4.12 cm. The ratio of airway height to nearby vertebral body lengths, at inspiration and expiration were, respectively: laryngeal height at C3: 0.56 and 0.56; tracheal height at C3: 0.4 and 0.39; at C5: 0.37 and 0.37; at T1: 0.59 and 0.59; and carina height: 0.91 and 0.94. The ratio of tracheal height to the thoracic inlet at inspiration and expiration was, respectively, 0.15 and 0.15. There was not a statistically significant association between airway diameter and phase of respiration. No association was found between tracheal height and body mass or height at the withers. Radiographic tracheal height can be measured independent of respiratory phase in sedated horses. It is suggested that the ratio of tracheal height to an adjacent bony landmark is more reliable for comparison between horses and tracheal height measurement should be made at C5, due to a lower standard deviation. If only thoracic radiographs are made, measurements of tracheal height at the thoracic inlet may be valuable.

“…There is a paucity of published veterinary data on CT evaluation of tracheal disease. [6][7][8] Our purpose was (1) to compare tracheal lumen diameter and length measurements obtained by CT and radiography and (2) to assess inter-observer variability. Measurements obtained from lateral and oblique radiographs (15°and 45°) were evaluated to determine which body position provides the most accurate tracheal measurements compared with CT.…”

“…[11][12][13][14] Moreover, there is some evidence, albeit limited, showing the success of these models in clinical applications. 4,16 FIG. These changes were visualised using direct endoscopy and computerised axial tomography, as these allow higher precision and versatility than standard radiological methods.…”
