In vitro study of magnetic resonance imaging artefacts of six supraglottic airway devices

Summary We investigated the artefacts created during magnetic resonance imaging by five different laryngeal mask airways: the Classic (cLMA™); the LMA ProSeal™; the LMA Unique™; the Ambu ® Disposable Laryngeal Mask; the LMA Supreme™; and one other supraglottic airway device, the i‐gel supraglottic airway. The devices were placed on top of and inside a phantom simulator to resemble the position in vivo. The artefacts with the cLMA, Unique and...
