Witryna8 lis 2024 · Abstract. Objective. Cerebral magnetic resonance imaging with the magnet of the cochlear implant receiver/stimulator in place causes artifacts and hinders evaluation of intracerebral structures. The aim of this study was to evaluate the internal auditory canal and the labyrinth in a 1.5T MRI with the magnet in place. Study Design. WitrynaParallel imaging (PI) is beset by the same types of artifacts that affect "regular" MR imaging: noise, motion, aliasing, chemical shift, Gibbs, susceptibility, RF-interference, etc. However, these artifacts may have slightly different appearances because they are acted upon by the complex PI reconstruction process, including generation of coil ...
