Easy to Use Patient Immobilizer for Stabilizing Limbs During MRI Imaging


MRI imaging sessions are often lengthy and uncomfortable for patients, taking an average of 45 minutes per session. As a result, patients naturally make voluntary and involuntary movements during scans. These movements blur the MRI image, reducing image quality and/or necessitating retakes. The reduction in image quality can impact the accuracy of diagnosis, and image retakes waste hospital time and money. Moreover, insurance carriers do not always cover image retakes; hospitals either pay the additional costs of retakes or simply do not re-image, which can further hinder diagnosis. Thus, there is a clear, unmet need for effective, inexpensive, time-efficient, and comfortable stabilization devices for MRI imaging.

Technology Description

Vanderbilt students have created a stabilization system for secure and stable MRI positioning of hands, wrists, knees, shoulders, and the lower back, using affordable, easy to use, and readily available materials. The system effectively reduces image blurring by inhibiting hand/wrist motion using a non-irritating film and a supportive frame with an adhesive surface. This device can simultaneously improve MRI diagnosis, enhance the patient experience, and minimize the time and financial burdens of image retakes.
