Description
Summary:Objective To evaluate the acquisition‐related factors influencing the quality of the brain volumes for further study of advanced neurosonography. Methods This was a prospective multicentre study. Five centres were asked to include five cases each, acquiring two volumes per case, at different gestational ages. Ten operators performed an advanced neurosonography per case. The potential influence of the following factors on the number of evaluable structures was assessed: vaginal/ abdominal acquisition, position of the head, gestational age, subjective quality of the volume and the acquiring operator itself. Results Four hundred and thirty‐two evaluations were included in the study. A total of 80% of the structures were evaluated satisfactorily in the axial plane, 67.1% and 55.1% in the coronal and sagittal plane, respectively. Sagittal volumes acquired transvaginally had a better quality than those acquired transabdominally. Gestational age affected the quality of axial and sagittal volumes (p
