A new image morphometric method of nuclear grading is described and assessed in the context of the evaluation of histological samples from ductal carcinoma in situ of the breast and cervical intraepithelial neoplasia. The method results in a continuous scaled variable, or nuclear grading scale, expressed in SD units from measured normal nuclei from breast(More)
Our objective was to grade, by computer-assisted quantitative image tile analysis, the intraepithelial neoplasia (also called dysplasia) that develops in esophagi of rats given N-nitrosomethybenzylamine (NMBA) for 5 weeks. To perform image tile analysis, the computer divides the video image of the neoplastic epithelium into a row of contiguous small(More)
