A resistive heating system for homeothermic maintenance in small animals.

Kersemans V, Gilchrist S, Allen PD, Beech JS, Kinchesh P, Vojnovic B, Smart SC - Magn Reson Imaging (2015)

Bottom Line: Fat-suppressed images and localized spectra were acquired with the twisted pair heater and a near-identical single strand heater during operation at maximum power.The efficacy of temperature maintenance was examined by measuring rectal temperature immediately following induction of general anesthesia and throughout and after the acquisition of a heater artifact-prone image series.The twisted pair wire heater does not interfere with MR image quality and maintains adequate thermal input to the animal to maintain body temperature.

Heat-loss recovery test. Temperature maintenance of 5 nude mice following induction of anesthesia and animal positioning using a DCE-MRI type scan as an additional heat source to the twisted pair heater wire. The red symbols indicate the time point at which the DCE-MRI type scan was stopped.

f0020: Heat-loss recovery test. Temperature maintenance of 5 nude mice following induction of anesthesia and animal positioning using a DCE-MRI type scan as an additional heat source to the twisted pair heater wire. The red symbols indicate the time point at which the DCE-MRI type scan was stopped.

Mentions: The results of the heat-loss recovery test, studying the recovery of the animal's heat loss upon anesthetic induction using a DCE-MRI type scan as an additional heat input, are presented in Fig. 4. The unpredictable temperature loss of up to 3 °C during induction of anesthesia, animal preparation and animal positioning was recovered within 15–25 minutes. Again, when the DCE-MRI type scan was stopped, the core temperature reached 36.3 °C for a target set to 37 °C.
