Abstract: To evaluate the agreement among experts for distinguishing between normal/arcuate and septate uterus by assessing the coronal plane of the uterus obtained by 3D ultrasound. We included 100 women evaluated between Jun-2016 and Jul-2016 with suspected uterine anomaly, using a single 3D data-set of each uterus. Two observers not involved with data acquisition, each one with 3-year experience with 3D-ultrasound, prepared the images using four different ultrasound techniques after training: standard coronal view using multiplanar mode (MP), a rendered view of the coronal plane (volume contrast imaging, VCI), a curved rendered mode (OmniView), and a curved rendered mode using HDlive. The four images for each uterus were combined in a single image, and the 100 combined images (one for each uterus) were anonymised and submitted to 15 experts (5 clinicians, 5 surgeons and 5 sonologists). These experts were asked to distinguish between normal/arcuate and septate uterus using the following definitions: normal/arcuate = normal uterine morphology or degree of distortion caused by the internal indentation is not clinically relevant; or septate uterus = the degree of distortion caused by the internal indentation is clinically relevant. Agreement across experts was assessed by kappa statistics. Considering all the experts, 357/1500 (24%) of the votes were for septate uterus with a good overall agreement (kappa = 0.62). Considering the three groups separately, the sonologists were more likely to consider the uteri as being normal and had a better inter-observer agreement (septate=92/500=18%; kappa=0.74) than both clinicians (septate=138/500=28%; kappa = 0.53) and surgeons (septate=127/500=25%; kappa=0.56). Experts, particularly sonologsits, have a good agreement to distinguish between normal/arcuate and septate uterus just by assessing the coronal plane of the uterus obtained by 3D ultrasound.
