From: Perinatal post mortem ultrasound (PMUS): a practical approach
Images of delivery and maceration related changes that degrade postmortem ultrasound image quality in a 22-week gestational-aged foetus. Sagittal T2-weighted postmortem MRI at 1.5 T (a) through the midline shows soft tissue oedema of the scalp, overlapping cranial sutures and underlying brain maceration. On the corresponding left trans-temporal view of the brain at postmortem ultrasound (b) and at axial postmortem MRI (c) at the level of the midbrain, it is difficult to delineate normal brain parenchymal architecture. In such cases, the imaging is described as ‘non-diagnostic’ and useful information cannot be gleaned by either imaging modality
