Upper row: CTP shows abnormalities in the lentiform nuclei bilaterally (white arrows) in a 43-year-old patient with transient global amnesia at 2.5 hours from symptom onset. Bottom row: PWI shows abnormalities (white arrows) at 4.0 hours from symptom onset. NEI indicates negative enhancement integral (CBV equivalent); MSD, maximum slope of decrease (CBF equivalent); MTE, mean time to enhance (MTT equivalent).

Acute CTP and subacute DWI in 2 female patients presenting with classic TGA symptoms. All CTP map findings for both patients were normal, while punctate DWI lesions were detected in the lateral hippocampus, bilaterally at 45 hours (62-year-old patient, upper row), and unilaterally at 64 hours (61-year-old patient, lower row) after symptom onset, respectively.
