gelatin, agar, polyvinyl alcohol, silicone, polyacrylamide, or agarose; organic dopped gells; paramagnetically dopped jells; and reverse micelle solutions. It is used by the radiologists to check the MRI machine). The PLMA was not attracted by the MRI but interfered with the MRI images (Figure).Finally in this case we used a LMA-C, total iv anesthesia and mechanical ventilation. The case was performed without problems.We conclude that the PLMA interferes with head and neck MRI images but that it could be used for other imaging locations since it is not attracted by the magnetic field of the MRI machine.
