Question

Which of the following statements is correct?

A) The anesthesia gas machine which is used in the out-of-OR environment should also be appropriate for use in the MRI scan room.
B) Standard portable infusion pumps can be used in zone 4 of the MRI suite as long as they are outside the 5 G line.
C) Standard patient monitoring systems may be used in the MRI scan room as long as they are firmly fixed to the MRI-compatible anesthesia machine and as close to the 5 G line as possible.
D) The anesthesia cart used in an MRI suite must be constructed from MRI-compatible materials and must contain only MRI-approved supplies and anesthesia equipment.

Answer 1

The correct statement is that the anesthesia cart used in an MRI suite must be made from MRI-compatible materials and contain only MRI-approved equipment, due to the strong magnetic fields present in MRI environments.

Step-by-step explanation:

The correct statement is: The anesthesia cart used in an MRI suite must be constructed from MRI-compatible materials and must contain only MRI-approved supplies and anesthesia equipment. This is because MRI suites have strong magnetic fields that can attract ferromagnetic objects, potentially causing injury or affecting the MRI image quality. Anesthesia equipment and any other materials used in an MRI environment must be specifically designed to be MRI-compatible to prevent such hazards.

MRI scanners use a powerful magnetic field to produce images, and the environment around an MRI scanner is divided into different zones, with Zone 4 being the area inside the scanner room itself. It is critical that any equipment used in this area is not affected by the magnetic field and does not contain ferromagnetic materials.

Devices and equipment labeled as MRI-safe or MRI-compatible have been tested to be safe in the MRI environment, meaning that they are not magnetic and will not be attracted to the MRI magnet. The use of standard equipment not specified as MRI-compatible can lead to serious safety issues and operational problems within the MRI suite.
