- W1479955910 abstract "To develop and evaluate a new clinical tool to automatically measure fetal arm adipose tissue area in a transverse section at mid-humeral level on 2D ultrasound images across a range of gestational ages. Fetal arm adipose tissue was automatically measured on 20 cross-sectional ultrasound images at mid-humeral level from optimally healthy fetuses between 21 and 31 weeks of gestation using a novel image analysis measurement tool. The measurement tool is based on a feature-based strategy, which makes use of structural and edge information to delineate the tissue boundaries. A shape-based strategy is used to complete the missing information in the shadowed area under the humerus bone. The final estimation of the adipose tissue layer is obtained after a contour smoothing step. The new methodology was compared to manual delineations, measured twice by the same expert on each of the 20 images. The differences between automatic and the first set of manual measurements were assessed using a Bland-Altman plot obtaining a mean of − 39.27 mm2 (−20.46%) and a standard deviation of 32.32 mm2. Compared to the second set of manual measurements the mean error was − 25.85 mm2 (−10.24%) with a standard deviation of 28.70 mm2. Good correlation of the automatic method with respect to manual delineations was observed across gestation. This method has the potential as an automated quantitative tool for assessment of fetal arm fat thickness. Supporting information can be found in the online version of this abstract.
