Ultrasound diagnostic criteria in breast disease

The Kasumi-Kamio parameters (margins, peripheral echoes, internal echoes, posterior echoes, lateral shadow cones) and the ratio between the longitudinal and transverse diameter of the breast lump form the basis for a list of standardised diagnostic criteria on which to base an analysis of breast disease that assesses the specificity and sensitivity of ultrasonography as a valid, reliable initial step in the diagnosis of breast tumours. The study was based on a series of 129 tumour cases and produced correct diagnosis in 89.28% of benign, 83.33% of malignant cases.
