Study of Enhanced MRI Imaging to Detect Anterior Ischemic Optic Neuropathy in Adults

What this Trial Is About

This research focuses on patients suspected of having anterior ischemic optic neuropathy NOIA, a condition affecting the optic nerve and vision. It aims to evaluate the accuracy of an optimized diffusion-weighted imaging DWI technique added to routine brain and visual MRI scans. The study is observational and seeks to improve detection methods for NOIA by assessing specific MRI signals in the optic nerve. Participants undergo a brain and visual MRI that includes two additional diffusion sequences lasting about 8 minutes, which are added to their scheduled MRI scans for diagnostic purposes. This enhanced imaging is being studied to see if it better identifies signs of NOIA by detecting a hypersignal and hyposignal in the optic nerve. During the study, patients provide informed consent and have their MRI results analyzed for sensitivity in detecting NOIA. The main measurement is the ability of the high-resolution diffusion sequence to identify changes in the optic nerve. Participation involves undergoing MRI scans as planned in their medical care, with no extra treatment given. The study is expected to continue until March 2028.
