The IETA (International Endometrial Tumour Analysis group) statement is a consensus statement on terms, definitions and measurements that may be used to describe the sonographic features of the endometrium and uterine cavity on grey-scale sonography, colour flow imaging and sonohysterography. The relationship between the ultrasound features described and the presence or absence of pathology is not yet known. However, the IETA terms and definitions form the basis for prospective studies to predict the risk of different endometrial pathologies based on their ultrasound appearance.
