Medical diagnosis of<unk>  in utero may use imaging, usually ultrasound or MRI. The extent of<unk>  is a very important prognostic factor. One study of 147 fetuses (49 normal, 98 with abnormalities) found that a simple measurement, the ratio of chest length to trunk (torso) length, was a useful predictor of postnatal respiratory distress. In a study of 23 fetuses, subtle differences seen on MRIs of the lungs were informative. In a study of 29 fetuses with suspected<unk> , the group that responded to maternal oxygenation had a more favorable outcome.<unk>  is diagnosed also clinically.
