Objective: To compare the accuracy of INTERGROWTH-21 (IG-21) versus Hadlock1 formulae for birth weight prediction on third-trimester ultrasound in a North American population.
Methods: This single-centre retrospective cohort study included all pregnant patients who had a third-trimester ultrasound between 34 and 36 weeks gestation and delivered a term singleton at our maternal-fetal medicine reference centre between April 1 and July 30, 2019. Estimated ultrasound fetal weight was calculated with both Hadlock1 and IG-21 formulae for each fetus, then reported on a centile curve to adjust for gestational age at delivery, and compared with the actual birth weight.
Background: Despite the common occurrence of syndesmotic injuries in ankle trauma, the distal tibiofibular relationship remains poorly understood. The aim of this study was to evaluate the anatomical impact of ankle sagittal positioning on the tibiofibular relationship in intact ankles by using a validated magnetic resonance imaging (MRI)-based measurement system.
Methods: In this radiologic study, 34 healthy volunteers underwent a series of ankle MRIs with the ankle stabilized in 3 positions: neutral position (NP), dorsiflexion (DF), and plantarflexion (PF).
