Case Selection
The investigated cohort for 2D vs. 3D TLV assessment included 8 cases
with abnormal lungs and 8 control cases from the iFIND project
[https://www.ifindproject.com] and clinical fetal cardiac MRI
databases. The abnormal cases included 6 cases of CDH (one with
concomitant BPS), and a further 2 cases of CLL (both CPAM). The eight
control cases were healthy control pregnancies and spanned approximately
the same gestational range as the abnormal cases (22-32 weeks
gestational age). In addition, 100 normal cases imaged as healthy
control participants for research purposes from 21-33 weeks gestational
age were used for the general assessment of 3D DSVR-derived fetal lung
volumetry growth chart. All datasets used in this research were
collected and processed subject to the informed consent of the
participants.
