Notice of Removal: Biological and experimental factors affecting the assessment of cervical softening during pregnancy with shear wave elasticity imaging

Conference Paper

Spontaneous preterm birth, the foremost source of neonatal mortality, could potentially be prevented by objectively detecting abnormal changes in the uterine cervix. Shear Wave Elasticity Imaging (SWEI) biomarkers can quantify cervical softening that precedes vaginal delivery. This task can be complicated by biological (i.e., heterogeneity of cervical stiffness and pregnancy history) and experimental confounders (i.e., posture during scanning). Here we investigate how these confounders influence shear wave speed (SWS) as an objective biomarker of cervical softening during pregnancy. We apply SWEI longitudinally in pregnant Rhesus macaques and compare SWS estimates from supine transabdominal (TA) and prone inter-cavitary (IC) approaches.
