Purpose: Transient global amnesia (TGA) patients were retrospectively reviewed to determine the usefulness of high-field
strength MRI in detecting probable ischemic lesions in TGA. Materials and Methods: We investigated the lesion detection
rate in patients with TGA using 1.5T and 3.0T MRI. Acute probable ischemic lesions were defined as regions of high-signal
intensity in diffusion weighted image with corresponding low-signal intensity in apparent diffusion coefficient map.
Results: 3.0T MRI showed 11 out of 32 patients with probable ischemic lesions in the hippocampus with mean lesion size
of 2.8 ± 0.6 mm, whereas 1.5T MRI detected no lesion in any of 11 patients. There were no significant differences in clinical
characteristics between the groups of 1.5 and 3.0T MRI. Conclusion: High-field strength MRI has a higher detection rate of
probable ischemic lesions than low-field strength MRI in patients with TGA.
