Fig. 1

 A right lateral thoracic radiograph of a healthy Shorthaired Chihuahua demonstrating the radiographic measurement of the absolute vertical tracheal diameter (VTD) at each of the caudal cervical, thoracic-inlet, and intra-thoracic tracheal regions. The figure also illustrates the radiographic measurements of the manubrium length (ML), thoracic inlet distance (Ti-D), and proximal 3rd rib-width (PR3-W) for calculating the manubrium- and thoracic inlet-tracheal indices (M-TI and Ti-TI) and proximal R3-tracheal score (PR3-TS).
