Differentiating ante-mortem from post-mortem findings on fetal and pediatric post-mortem imaging

Interpreting fetal and pediatric post-mortem imaging remains challenging. One of the most important aspects of post-mortem computed tomography (PMCT) and post-mortem magnetic resonance imaging (PMMRI) image interpretation is to be able to confidently differentiate ante-mortem pathology from the range of normal post-mortem changes that occur. In this article, we discuss the normal post-mortem findings in fetal and pediatric imaging for the central nervous system, thorax, abdomen, and musculoskeletal system, and the limitations of computed tomography (CT) and magnetic resonance imaging (MRI) in post-mortem imaging.
