Long‐term sequelae of hippocampal lesions in patients with transient global amnesia: A multiparametric MRI study

BACKGROUND MRI signal diffusion‐weighted imaging (DWI) hyperintensity in the hippocampus in patients with transient global amnesia (TGA) are resolved within several days after the onset of TGA. PURPOSE To use multiparametric MRI to unravel the sequelae of TGA. STUDY TYPE A prospective longitudinal study. POPULATION Eight TGA patients. FIELD STRENGTH/SEQUENCE A 3.0T Siemens Tim Trio MRI scanner with T 1 ‐weighted MPRAGE, diffusion‐weighted echo...
