13Detection of wooden foreign bodies in dogs can be challenging. A retrospective, cross-sectional study 14 was done to describe computed tomographic (CT) signs associated with wooden foreign bodies, and to 15 estimate the accuracy of CT for detection of wooden foreign bodies. Patient records and CT images were 16 reviewed of 72 dogs that had a history of suspected stick injury and CT of the affected body part, or 17 possible wooden foreign object reported on CT, and had surgical exploration during the same period of 18 hospitalization. Duration of clinical signs was acute in 48 (67%) dogs and chronic in 24 (33%). Wood was 19 removed from 55 dogs, including a piece of a tree or shrub in 33 (60%) instances, kebab stick in 8 (15%), 20 piece of bamboo garden cane in 2 (4%), cocktail stick in 2 (4%), thorn in 1 (2%), and unidentified wood in 21 the remaining 9 instances. Based on review of CT images with knowledge of the surgical findings, 22 sensitivity of CT for wooden foreign bodies was 79% (95% CI 65-89%), specificity 93% (78-98%), positive 23 likelihood ratio 11.5 (2.9-44.1), and negative likelihood ratio 0.23 (0.13-0.41). Wooden foreign bodies 24 were predominantly rectangular or linear, with median length 48mm (range 2-270mm), median 25 thickness 3mm (range 1-22mm), and median attenuation 111HU (range -
