Journal ArticleDOI
Three-Dimensional Power Doppler Ultrasonography for Diagnosing Abnormally Invasive Placenta and Quantifying the Risk.
Sally Collins,Gordon N. Stevenson,Abdulla Al-Khan,Nicholas P. Illsley,Lawrence Impey,Leigh Pappas,Stacy Zamudio +6 more
TL;DR: The marker Acon provides a quantitative means for diagnosing abnormally invasive placenta and assessing severity and, if further validated, subjectivity could be eliminated from the diagnosis of abnormalities.
Journal ArticleDOI
Fully automated, real-time 3D ultrasound segmentation to estimate first trimester placental volume using deep learning
Padraig T. Looney,Gordon N. Stevenson,Kypros H. Nicolaides,Walter Plasencia,Malid Molloholli,Stavros Natsis,Sally Collins +6 more
TL;DR: A new technique to fully automate the segmentation of an organ from 3D ultrasound (3D-US) volumes, using the placenta as the target organ, demonstrated good similarity to the ground-truth and almost identical clinical results for the prediction of SGA.
Journal ArticleDOI
Monitoring of Cerebrovascular Reactivity for Determination of Optimal Blood Pressure in Preterm Infants
Cristine Sortica da Costa,Marek Czosnyka,Marek Czosnyka,Peter Smielewski,Subhabrata Mitra,Gordon N. Stevenson,Topun Austin +6 more
TL;DR: Continuous monitoring of cerebrovascular reactivity allows the determination of MABPOPT in preterm neonates and correlates deviations from MABpOPT with mortality and intraventricular hemorrhage.
Journal ArticleDOI
Influence of power Doppler gain setting on Virtual Organ Computer-aided AnaLysis indices in vivo: can use of the individual sub-noise gain level optimize information?
TL;DR: To demonstrate the influence of gain setting on the calculated Virtual Organ Computer‐aided AnaLysis (VOCAL™) three‐dimensional indices and define a point, the sub‐noise gain (SNG), at which maximum information is available without noise artifact.
Journal ArticleDOI
Understanding abnormal uterine artery Doppler waveforms: A novel computational model to explore potential causes within the utero-placental vasculature.
TL;DR: A more anatomically complete computational model is presented, explicitly incorporating a structural description of each component of the uterine vasculature, and crucially including myometrial arterio-venous anastomoses as parallel pathways for blood-flow away from the placental bed, which suggests that to appropriately interpret UtA Doppler waveforms they must be considered to be reflecting changes in the entire system, rather than just the spiral arteries.
