In magnetic resonance imaging (MRI) examinations for dogs, general anesthesia or sedation is required for immobilization. It is difficult to prevent hypothermia induced by general anesthesia or sedation due to limitations in body temperature management methods, such as lack of force-warming equipment, including magnetic materials. A hot water bottle (HWB) is one of the few tools that can be brought into an MRI examination room, and can contribute to the prevention Citation: Shimizu, Y.; Kanda, T.; Kutara, K.; Ohnishi, A.; Saeki, K.; Miyabe, M.; Asanuma, T.; Ishioka, K.

In this study, we aimed to retrospectively investigate the effects of HWBonbodytemperature during MRI examinations in dogs under general anesthesia. We obtained validated data from 100 dogs who underwent MRI under general anesthesia. The decrease in rectal temperature 15 min after intubation was significantly smaller in the group using HWB than in the group not using HWB. Our results suggested that the use of hot water bottles might be one of the methods to attenuate hypothermia in the early period but should not be expected for complete prevention of hypothermia, anditwasnotrecommendablenecessarilyforbodytemperature management during MRI examinations in dogs under general anesthesia.
