Infusion pump performance in an MR environment.

Area of Science:

• Medical Imaging
• Biomedical Engineering
• Critical Care Medicine

Background:

• Magnetic resonance imaging (MRI) is often contraindicated for critically ill patients due to life support equipment concerns.
• Limited availability of MRI-compatible medical devices restricts imaging for this vulnerable population.
• The IVAC P3000 infusion pump is commonly used in critical care settings.

Purpose of the Study:

• To evaluate the safety and performance of the IVAC P3000 infusion pump within a magnetic resonance imaging environment.
• To assess potential risks including device malfunction, patient safety, and magnetic field interference.
• To determine the feasibility of using the IVAC P3000 infusion pump during MRI scans of critically ill patients.

Main Methods:

• The IVAC P3000 infusion pump underwent rigorous testing to assess its compatibility with MRI.
• Safety evaluations included assessing the pump's performance under varying magnetic field strengths.
• Gravimetric tests were conducted to measure any physical effects of the magnetic field on the pump.

Main Results:

• The IVAC P3000 infusion pump operated within acceptable parameters at a static magnetic field of 10 mT.
• The study addressed and resolved issues related to image quality degradation caused by the pump.
• Specific measures, such as pump placement, were implemented to mitigate motion artifacts.

Conclusions:

• The IVAC P3000 infusion pump demonstrates suitability for use in magnetic resonance imaging environments.
• This research supports the expanded use of MRI for critically ill patients requiring infusion support.
• Further validation may enable broader application of MRI in critical care scenarios.
