Gas Anesthesia & Animal Monitoring
Facilities for inhalation anesthetics during imaging are available on both the 8.5T and 4.7T systems.
A nose cone is used for anesthetic inhalation. Respiratory monitoring is available through the use of a pressure transducer placed on the abdominal area of the animal, and ECG monitoring is available through ECG leads. The resulting signals are displayed on a Bruker Physiogard unit (Figure 1), and can be used for triggering of the MRI sequences. Triggering can be respiratory, cardiac, or a combination.
