This is a small pilot study comparing a rapid method of
MRI measurement of amniotic fluid volume with standard
manual planimetric (MP) approaches. The rapid method
uses projection hydrography (PH) to compare amniotic
signal with a reference fluid volume. Comparison is made
with ultrasound as a gold standard modality. Results
show that PH shows strong correlation with MP, and they
both show moderate correlation with ultrasound. Further
development of this technique may prove useful in MRI
assessment of the fetus.
