[Analysis of the performance of several technicians in the echographic evaluation of the uterus].

The reproducibility degree in echographic biometry of uterus, studied by three diameters (longitudinal, transverse and antero-posterior), is mainly influenced by the anatomic characteristics of the structures. Starting from this observation a study about if and how much the understanding difficulties can influence differently the evaluation by four operators has been performed. Data, obtained from ten women, have been elaborated for appraising precision and accuracy of the four operators. Results show an almost univocal interpretation of the images and also that the data inhomogeneity in the less reproducible diameters valuation is caused by real difficulty in the interpretation of the pictures.
