Description
Summary:Objective To compare radiographic and computed tomography (CT) measurements of tracheal size as would be made for the purpose of tracheal stent size selection. Study Design Cross‐over. Animals Dogs (n = 15). Methods Canine cadavers without evidence of tracheal or respiratory disease were used for CT and digital radiography of the neck and thorax. Three observers each made 3 independent measurements at each of 5 tracheal locations, and also measured tracheal length, on each radiograph and for each CT scan on each cadaver. Results CT tracheal measurements were on average 1.03 mm larger (P
