Diagnostic accuracy of fetal ultrasound and fetal magnetic resonance relative to the postnatal diagnosis or autopsy and concordance (n = 623).

Indication	Diagnostic accuracy relative to postnatal diagnosis					Concordance between fetal ultrasounsd and MRI n (%)
	Of fetal ultrasound n (%)		Of fetal MRI n (%)		-value

-value of the Chi-squared test for the differences in diagnostic accuracy of fetal ultrasound (US) and fetal magnetic resonance imaging (MRI) for all indications and for each indication. The asterisk () indicates a statistically significant difference (Chi-squared test or Fischer’s exact test, ) in the concordance between fetal US and fetal MRI for the different indications.
