B-Flow Sonography for Evaluation of Basal Cerebral Arteries in Newborns

Abstract

The aim of the study was to evaluate the B‑flow sonography (BFS) to image the basal cerebral arteries in newborn infants. For this purpose 34 newborns, who underwent standardized ultrasound of the brain including BFS, color Doppler (CDS) and power Doppler (PDS) techniques were retrospectively assessed. Delineation of the anterior communicating (Acom), the posterior communicating (Pcom), the middle cerebral (M1 and M2 segments), the anterior cerebral (A1 and A2 segments), and the posterior cerebral artery (P1 and P2 segments) were visually scored. Vessel delineation was better with BFS compared with CDS and PDS for the M2 segment (p = 0.0006 and p = 0.0136) and P2 segment (p = 0.0021 and p = 0.0014). Superior detectability was also noted for the Pcom with BFS compared with PDS (p = 0.0062). For all other vessel segments no significant differences were found. In conclusion BFS is feasible to image the basal cerebral arteries in newborns with an equal or better vessel delineation compared with standard vascular ultrasound methods.
