    Assessment of fetal lung volumes and liver
    herniation with magnetic resonance imaging in
    congenital diaphragmatic hernia.


    Am J Obstet Gynecol, Nov.2000; 183: 1067-9
     


    Objective
    : Authors evaluated the use of fetal magnetic
    resonance imaging in predicting outcomes after
    ultrasonographic diagnosis of left-sided congenital
    diaphragmatic hernia.



    Study
    Design: Forty-one pregnant women carrying fetuses
    with congenital diaphragmatic hernia underwent 43
    magnetic resonance imaging scans. 
    Lung volumes were calculated by summing the
    areas on 6-mm axial sections. 
    The presence or absence of liver herniation
    was noted.  A
    liver/diaphragm ratio was obtained by using the
    distances from the superior aspect of the liver 
    and the diaphragmatic remnant to the apex of
    the chest.



    Results: Mean gestational age was 26 weeks and
    overall survival was 59%. 
    Neither right, left, nor total lung volume
    measurements were predictive of survival. 
    Liver herniation into the left side of the
    chest was predictive of outcome at P <.05.  The
    liver/diaphragm ratio was predictive of outcome at P=.03.



    Conclusion:
    Fetal magnetic resonance imaging permits calculation
    of lung volumes, but these volumes are not
    predictive of outcome. 
    However, both the presence of liver
    herniation and the volume of liver within the chest,
    as reflected by the liver/diaphragm ratio, help
    predict outcome in left-sided congenital
    diaphragmatic hernia.
