The proposed damage assessment procedure aims not only at detecting the occurrence of structural anomalies, but also at localising the damage in the investigated structure.

The study is titled "Whole-exome sequencing in the evaluation of fetal structural anomalies: A prospective cohort study of 234 patients with unselected fetal structural anomalies". The study was funded by the Columbia University Institute for Genomic Medicine.
Congenital fetal cardiac anomalies compromise the most common group of fetal structural anomalies.
Besides hygroma, associated sonographic detectable structural anomalies were observed in 17 cases (53.1%).
Modern high-resolution brain magnetic resonance imaging (MRI) has allowed detailed analysis of the cortical, white matter, and deep gray structural anomalies in HPE in living humans.
In the largest study to date, research sponsored by the National Institutes of Health in 1993 found that in 15,000 low-risk pregnancies, ultrasound detected only 17percentt of fetal structural anomalies before 24 weeks.
It is possible instead that prenatal diagnosis is selectively picking up T21 cases with serious heart or other structural anomalies with lower expected late fetal survival, thus depressing late FD proportions among those not PD.
The results as a whole support the hypothesis that movement analysis using image registration offers a possible method for detecting underlying structural anomalies and encourages further investigation.
Study design: Based on a series of 32 cases, we determined the sonographic morphology of the hygroma, associated structural anomalies, karyotypes and autopsy findings.
