Recommended post-mortem imaging flowchart for non-invasive investigation of perinatal loss. Small foetuses present a challenge for post-mortem imaging, and care should be taken when interpreting imaging results in this cohort. A foetus weighing over 500 g provides the greatest likelihood for a diagnostic quality 1.5 T MRI study [14], and those weighing < 300 g are best suited for micro-CT or high-field MRI [32]. Where neither MRI nor micro-CT is available, ultrasound may be attempted but there is a higher likelihood of a false or non-diagnostic result [26, 58]. Foetuses weighing between 300 and 500 g have been reported to take > 7 days to iodinate and therefore delay micro-CT imaging. If available, 3 T MRI could be attempted for this foetal cohort [22]
