Which material can help reduce artifacts in MR imaging?

Plastic is the correct choice for reducing artifacts in MR imaging due to its non-magnetic properties. Unlike metals, which can cause significant magnetic susceptibility artifacts by distorting the local magnetic field, plastics generally do not interfere with the magnetic field used in MRI. This characteristic makes plastic a favorable material for various components in MRI machines and for any items that may be in the MRI suite, as they do not create additional artifacts that compromise image quality.

In the context of MR imaging, materials that maintain neutrality in regards to the magnetic field are crucial for obtaining clear and accurate images. Metals can lead to severe artifacts due to their ferromagnetic properties, and even non-ferrous metals can cause issues related to signal loss or distortion. Wood and glass, while they are not ferromagnetic, do not have the inherent optimal characteristics that plastic provides for mitigating artifacts and ensuring clearer imaging outcomes in MRI scans.
