Abstract

After repair work was performed on a magnetic resonance (MR) imager, images of the brain were obtained from a patient with an acoustic neuroma on the left side. On the images, the tumor appeared to be on the right side. The reversal occurred due to a reversal of gradient wire connections. To prevent such an event after MR imager repair, a phantom with side markers should be imaged.
