Diagnostic accuracy and limitations of post-mortem MRI for neurological abnormalities in fetuses and children

•Post mortem MRI (PMMRI) has a sensitivity of >87% for detecting cerebral malformations, intracranial bleeds and neurological cause of death.•PMMRI provides important diagnostic information in >50% of fetuses where conventional brain autopsy is non-diagnostic.•PMMRI is currently poor at reliably identifying ischaemic brain injury, especially in fetuses.
