Method and Apparatus for the Biopsy and Diagnosis of Precancerous Inflammation and Crohn's Inflammatory Bowel Disease

摘要

A method and apparatus for determining a likelihood of Crohn's, quantifying a degree of Crohn's disease or determining a heightened cancer risk by analyzing a cell preparation of cell collected from a patient's GI tract. The GI tract cellular sample is fixed on a microscope slide and analyzed by a microscope combined with an image acquisition system and a computer having an image recognition system. The image recognition system detects inflammatory cells that are implicated in the body's inflammatory response and counts how many of such cells are on the slide. The computer generates an absolute number of such cells and percentage values for such cells out the total number of inflammatory cells classified. The computer then utilizes the absolute numbers, the ratios of inflammatory cells with respect to each other—or a combination of both to generate a score. The score represents a probabilistic determination of disease or a quantification of disease or pre-disease.

主权项

1. A method of determining a Crohn's condition comprising the steps of:
examining a slide comprising a cellular sample collected from a GI tract with a microscope combined with an image acquisition system; acquiring images of cells in said cellular sample; analyzing said images of said cells with an image recognition system to detect at least two types of inflammatory cells; counting individual cells of each of said at least two types of inflammatory cells; calculating a total number of inflammatory cells on said slide; generating a first percentage value, said first percentage value corresponding to a percentage of said first inflammatory cell type out of said total number of inflammatory cells; generating a second percentage value, said second percentage value corresponding to a percentage of said second inflammatory cell type out of said total number of inflammatory cells; comparing said first percentage value to a first expected value and comparing said second percentage value to said to a second expected percentage value; and generating a score based on said comparisons, said score indicating a likelihood of disease.
