CONTRIBUTIONWhat are the novel findings of this work? The prevalence, clinical relevance and appropriateness of management of T-shaped uterus is not fully understood, due to the lack of objective criteria for its diagnosis. This study developed an objective definition of T-shaped uterus based on the diagnosis made most often by representative expert clinicians, surgeons and sonologists. We identified three uterine morphometric measurements in the coronal plane, with cut-offs (lateral internal indentation depth ≥ 7 mm, lateral indentation angle ≤ 130 • and T-angle ≤ 40 • ) that have good diagnostic test accuracy and fair-to-moderate reliability for the diagnosis of T-shaped uterus.What are the clinical implications of this work? These three measurements, with cut-offs, can be used to confirm the diagnosis when there is suspicion of T-shaped uterus on subjective assessment of the uterine cavity. When these CUME definitions and criteria are used, doctors and patients can be confident that the diagnosis Correspondence to: Prof. A. Ludwin, of T-shaped uterus has high probability of being correct. Using these criteria will allow elucidation in future studies of the prevalence, clinical relevance and management of T-shaped uterus. ABSTRACT Objectives To identify uterine measurements that are reliable and accurate to distinguish between T-shaped and normal/arcuate uterus, and define T-shaped uterus, using Congenital Uterine Malformation by Experts (CUME) methodology, which uses as reference standard the decision made most often by several independent experts.Methods This was a prospectively planned multirater reliability/agreement and diagnostic accuracy study, performed between November 2017 and December 2018, using a sample of 100 three-dimensional (3D) datasets of different uteri with lateral uterine cavity indentations, acquired from consecutive women between 2014 and 2016. Fifteen representative experts (five clinicians, five
