Upright Magnetic Resonance Imaging (MRI)
A method of Magnetic Resonance Imaging (MRI) that allows for scanning of the patients in the positions they experience their problems— standing, bending, sitting, leaning, as well as the standard lying down. With Chiari this can be an invaluable tool, much better than the standard supine (horizontal) MRI, because it allows images that include the effects gravity is having on herniation (tonsillar ectopia). Additionally, it can make certain comorbid conditions, such as Tethered Cord, more visible.
