Paired coronal postmortem ultrasound images (obtained in the water bath) and T2-weighted postmortem MRI at 1.5 T in the same 20-week gestational-aged foetus. The images were obtained 4 days after death, demonstrating normal anatomy. Images through the frontal horns (a, b) and the posterior horns (c, d) of the lateral ventricles demonstrate how detailed anatomy of the brain, including sulcation and appearances of the ventricles can be adequately reviewed by ultrasound, and not necessarily require further cross-sectional imaging
