“…However, we do not confirm literature data indicating that grey-level histograms may be helpful in differentiation between benign and malignant lesions. (6). In our group of patients these differences were not statistically significant.…”

Disadvantage of ultrasonography is its dependence on subjective assessment of displayed images. The way how to minimize both intraobserver and interobserver differences is creation of standard conditions for examination including a quantitative approach to evaluation of tissue reflectivity. The oldest mode of standardisation is standardised A- scan, used in ophthalmology. It enables differentiation of echoes, reflected from different ocular structures and is helpful in assessment of extraocular muscle thickness. Standardisation of B- scan depends on the type of diagnostic device and is based on quantification of image echogenicity. In our study reference values of grey-level histogram were established for some thyroid diseases using standard setting of imaging parameters. Results indicate that both standardised A- and B- scan should be helpful in differential diagnostics.

“…Although at least one study has reported that benign and malignant solid breast masses could be differentiated based on US alone (83), subsequent studies have not confirmed this hypothesis, and it is now generally believed that at the present time there are no US features that, by themselves, are sufficient evidence to forgo biopsy. Newer techniques being explored to improve the ability of US to differentiate benign and malignant masses include intensity histogram analysis (84) and disparity processing, in which the sonographer slightly varies the pressure of the probe on the breast surface, and the apparent displacement of the tissue is measured by analysis of the correlation between images obtained at different parts of this compression cycle (85). This measurement of the elastic properties of the lesion is similar to that employed in breast elastography (briefly described below).…”

“…For breast tumors, analysis of histograms based on reflected ultrasound may also have a role in distinguishing malignant tumors from benign masses. 10,11 Loren et al 12 reported that a computerassisted system for the analysis of lymph node metastasis in patients with esophageal carcinoma could increase the accuracy of EUS tumor staging. They assessed echogenicity, whole-node heterogeneity, and regional gray-scale variability.…”
