Distinguishing a monitoring artifact requires expertise and adeptness. This can be practically challenging during the course of an anesthetic. We report a case, wherein we experienced episodes of aberrant pulse-oximeter values suggestive of desaturation with normal waveforms, occurring during a particular sequence of magnetic resonance imaging (MRI) performed under general anesthesia, which in fact was an artifact induced by the 3 T MRI during the diffusion tensor imaging sequence.
辨别监测伪像需要专业知识和熟练技能。在麻醉过程中，这实际上可能具有挑战性。我们报告了一例病例，在全身麻醉下进行的特定序列磁共振成像（MRI）过程中，我们遇到了脉搏血氧饱和度仪值异常提示血氧饱和度下降但波形正常的情况，而这实际上是3T MRI在扩散张量成像序列期间产生的伪像。
