title: [Reproducibility of the sonographic determination of the size of intra-abdominal space-occupying lesions].
abstract: The reproducibility of sonographic measurements was checked using 255 measurements on 57 intra-abdominal masses. It was shown that differences of measurements carried out independently by two observers increased in a linear manner with tumour diameter. Relative differences in measurement averaged 10%, but in 5% of cases they reached 30%. Somewhat better results were obtained with small tumours and for measurements lying strictly in the axis of the body. The significance of these findings in clinical practice, particularly for tumour follow-up, is discussed.
