MRI prenatal diagnosis for vasa previa when inconclusive ultrasonography
results come, cons and pros?
Abstract
[Abstract] Objective To explore the MRI assistance in diagnosing of
vasa previa when inconclusive ultrasonography results come. Methods From
January 2018 to December 2021, 12 patients with suspected vasa previa
but inconclusive ultrasonography diagnoses at 23-25w or 31-33w were
enrolled into the study group. 51 patients diagnosed by ultrasonography
as mild ventriculomegaly with no vasa previa were enrolled into the
control group. Both groups had taken MRI scanning during the 3rd
trimester to check the existence of vasa previa. Placentas from both
groups were checked to confirm the existences of vasa previa immediately
at delivery, and postoperatively by pathology. Results In the 12
patients from the study group, MRI demonstrated vasa previa in 11
patients. The rest one was excluded of vasa previa by MRI. In all the 51
patients from the control group, MRI had excluded vasa previa. Pathology
examination after delivery had confirmed these MRI diagnoses. Conclusion
When inconclusive ultrasonography interpretations on vasa previa come,
MRI may offer some assistance in diagnosis.
