Fig 2. A 50-year-old woman (patient 3) with TGA. All initial DWIs (A) obtained at 4 hours 30 minutes after the onset of symptoms and follow-up DWIs (B) after 3 days at b = 1000/5 mm do not show the lesion. Follow-up DWIs at b = 1000/3 mm, b = 2000/3 mm, and b = 3000/3 mm show a bright lesion (arrows) in the right hippocampal body, though the signal intensity-to-noise ratio becomes poor by increasing the b-value.
