Head position matters: Position‑dependent vestibular flow void artifacts in inner ear MRI and their clinical implications
Recent Publication
Researchers from Krems University Hospital and Johns Hopkins University have discovered that the position of the head during an MRI examination can influence the image of the inner ear. The study shows that even small changes in the head tilt angle lead to different artefacts in the MRI image, which are caused by magnetically triggered fluid movements in the inner ear. These so-called "flow voids" are dependent on the head position and can easily be mistaken for pathological changes. The results help radiologists to better interpret MRI images and optimise examination protocols.
