MR Imaging of Wallenberg Syndrome Using Accelerated 3D-FLAIR with T2 Preparation and Magnetization Transfer Contrast:...

We report a case of Wallenberg syndrome associated with vertebral artery occlusion and suspected atherosclerotic changes. The patient was evaluated using accelerated 3D fluid-attenuated inversion recovery MRI incorporating T2 preparation and magnetization transfer contrast pulses. This technique enabled a shortened acquisition time while preserving high image contrast, allowing clear visualization of the lateral medullary infarction. This approach provides a non-contrast, high-resolution method for assessing brainstem infarcts and may contribute to improved diagnostic accuracy in the acute setting.
