High Resolution Diffusion-Weighted Image of Magnetic Resonance Imaging Detects the Hippocampus Lesion with Excellent Sensitivity
Abstract
Transient global amnesia (TGA) is characterized by anterograde amnesia. It is presumed to be caused by hippocampal transient ischemia or metabolic dysregulation. Although diffusion-weighted imaging (DWI) on magnetic resonance imaging (MRI) can visualize the lesion, the diagnostic sensitivity is still under discussion.A 66-year-old female was diagnosed with TGA as indicated by clinical symptoms and radiological findings.In addition, high-resolution DWI clearly detected the hippocampal lesion than conventional DWI.High-resolution DWI is useful to detect the hippocampal lesion in TGA patient.Following to the previous reports, this result supports high-resolution DWI would be recommended to TGA diagnosis.
