The MRI Compatible Concentric Masks Package provides anesthesia delivery for rodent research in magnetic resonance environments. The concentric tubing mask design offers enhanced positioning flexibility compared to traditional cone masks, providing a wider field of view around the animal's head while maintaining secure anesthesia delivery. The integrated scavenging system effectively removes waste gas from around the animal's nose, improving safety and reducing environmental contamination.
Constructed entirely from non-metallic materials, the system is fully compatible with MRI, PET, and SPECT imaging environments. The height-adjustable design accommodates various experimental setups and can be fixed using either a mounting bracket or platform system. Multiple configuration options are available including single-channel, dual-channel, and five-channel configurations to support different experimental requirements.
How It Works
The concentric tubing mask system delivers anesthetic gas through a central supply tube while simultaneously removing waste gases through an outer concentric scavenging pathway. This design creates a continuous flow pattern that maintains consistent anesthetic concentration at the animal's nose while preventing accumulation of expired gases. The non-metallic construction eliminates magnetic susceptibility artifacts that could interfere with image quality in MRI environments.
The height-adjustable mounting system allows precise positioning of the mask relative to the animal's head, accommodating different body sizes and experimental orientations. The scavenging system operates on passive flow principles, drawing waste gases away from the breathing zone through the outer tube while fresh anesthetic gas is supplied through the central pathway. This configuration maintains a stable anesthetic environment while minimizing environmental contamination in the imaging suite.

Practical Tips
Position the mask 2-3mm from the animal's nose and monitor respiratory rate to ensure adequate anesthetic delivery without restricting natural breathing.
Why: Proper positioning maintains effective anesthesia while preventing respiratory compromise.
Inspect all tubing connections before each use and replace tubing that shows signs of cracking or gas permeability loss.
Why: Compromised tubing can lead to anesthetic leaks and inconsistent delivery.
Verify scavenging system function at the start of each session by confirming waste gas flow through the outer tube.
Why: Effective scavenging prevents accumulation of anesthetic gases in the imaging environment.
Calibrate gas flow rates based on animal weight and anesthetic protocol, adjusting for changes in respiratory patterns during imaging.
Why: Proper flow calibration ensures consistent anesthetic depth throughout the imaging session.
If anesthetic depth appears inadequate, check for leaks in the delivery system and verify proper mask positioning before increasing gas flow rates.
Why: System leaks are a common cause of apparent anesthetic insufficiency and should be addressed before protocol adjustments.
Perform test scans with the anesthesia system in place to verify absence of imaging artifacts before beginning data collection protocols.
Why: MRI compatibility verification ensures that the anesthesia system does not compromise image quality or experimental data.
Use separate tubing sets for different anesthetic agents to prevent cross-contamination and maintain protocol consistency.
Why: Anesthetic cross-contamination can affect experimental reproducibility and animal safety.

Compliance
What gas flow rates are recommended for different animal weights?
Consult product datasheet for specific flow rate recommendations. Generally, flow rates are adjusted based on animal size with mice requiring lower rates than rats, but specific protocols depend on anesthetic agent and experimental duration.
How does the scavenging system prevent waste gas accumulation?
The concentric tube design creates continuous waste gas removal through the outer tube while delivering fresh anesthetic through the central tube, maintaining a clean breathing environment around the animal's nose.
Can this system be used with different anesthetic agents?
The system is compatible with standard volatile anesthetics used in rodent research. Gas compatibility depends on tubing materials and system specifications - consult product datasheet for approved anesthetic agents.
What maintenance is required for the scavenging system?
Regular inspection of tubing connections for leaks, cleaning of gas pathways, and verification of scavenging flow rates. Replace tubing according to usage frequency and manufacturer recommendations.
How is the mask positioned for optimal anesthetic delivery?
Position the mask opening 2-3mm from the animal's nose using the height adjustment mechanism. Too close restricts breathing, too far reduces anesthetic efficiency.
What imaging artifacts should I check for during MRI compatibility testing?
Verify absence of signal dropout, distortion, or noise artifacts in critical imaging regions. Perform test scans with and without the anesthesia system to confirm compatibility.
Can multiple animals be anesthetized simultaneously with multi-channel configurations?
Multi-channel configurations allow independent anesthetic delivery to multiple animals, but each channel requires separate gas flow control and monitoring for proper anesthetic depth management.
