METHOD FOR DETERMINING THE DEGREE OF CERVICAL DYSPLASIA Russian patent published in 2021 - IPC A61B1/303 A61B5/107 A61B5/1455 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely obstetrics and gynecology, and can be used to determine the degree of cervical dysplasia. In patients during a clinical examination using a video colposcope, a video examination of the vagina and uterine cervix is recorded in Full HD resolution. A snapshot is obtained that displays the anatomical structure, the affected areas of the surface of the uterine cervix and the outer portion of the cervical canal. The image is processed using ImageJ software. With the help of software tools, the amount of affected tissue per unit area of the entire surface of the uterine cervix is calculated with the introduction of diagnostic intensity indices of the affected area, assessing the severity of cervical dysplasia, according to the proposed formula: where IndGV is a uniform intensity index; IndInt is the intensity index of the affected area; dGV is the range of change in the gray color of the affected area. where Area is the total surface area of the uterine cervix, % area is the percentage of the affected area on the surface of the uterine cervix. CIN1 corresponds to IndGV = 4.75. CIN2 corresponds to IndGV = 6.99. CIN3 corresponds to IndGV = 8.46. In this case, CIN I is a mild degree of dysplasia, CIN 2 is a moderate degree of dysplasia, CIN 3 is a severe degree of dysplasia.

EFFECT: method provides determination of the degree of dysplasia due to a quantitative indicator of the intensity of the affected area.
