Presentation transcript:

T1-weighted image (TR/TE, 550/14; signals acquired, 2; matrix, 205/256; section thickness, 5 mm; section gap, 0.5 mm; FOV, 16 cm) of a neonate from the HIE group (HIE grade 2) imaged at 3 days of age. T1-weighted image (TR/TE, 550/14; signals acquired, 2; matrix, 205/256; section thickness, 5 mm; section gap, 0.5 mm; FOV, 16 cm) of a neonate from the HIE group (HIE grade 2) imaged at 3 days of age. The image shows higher SI in the posterolateral putamen (arrow) than in the posterior limb of the internal capsule (arrowhead) and abnormal SI in the lateral thalami. The neonate was born at a gestational age of 40+4 weeks, the mother underwent an emergency cesarean delivery for fetal distress, and the neonate was resuscitated. The Apgar score was 0–4–5 (at 1, 5, and 10 minutes). At 5 years of age, this child has an abnormal development (outcome group 3). L. Liauw et al.
