DIFFERENTIAL DIAGNOSTIC TECHNIQUE FOR BENIGN AND MALIGNANT BREAST PATHOLOGIES Russian patent published in 2014 - IPC A61B5/01 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to oncology, to radiothermometric methods for examining breast cancer. The breast tissue temperature is measured by 9 symmetrical points on both sides by radiothermometry with measuring electromagnetic emission. That involves sequential measurement of the core and skin temperatures at 9 symmetrical points of each breast: the core temperature is first measured on the left and right breasts with the use a core temperature sensor, and then the skin temperature is measured on the left and right breasts by using a skin temperature sensor. Maximum core and skin temperatures for each breast are found by four computer analyser images comprising the presented core and skin temperatures in 9 symmetrical points of each breast and the average temperatures; a difference of the above and the respective average core and skin temperatures of each breast are determined. The derived differences are summed up for the right and left breasts respectively. The greatest Qmax of these values is stated. That is followed by calculating the maximum difference of the core temperatures and the maximum difference of the skin temperatures between the symmetrical points of the left and right breasts - Kcore and Kskin. If the symmetrical points with the maximum difference of the core temperatures and the maximum skin temperatures appear to be localised the same, the derived values are to be summed up to calculate the greatest value Rmax. If the symmetrical points with the maximum difference of the core temperatures and the skin temperatures are localised differently, the maximum difference of the core temperatures Kcore is added to the difference of the skin temperatures in the symmetrically localised points, while the maximum difference of the skin temperatures Kskin is added to the difference of the core temperatures in the symmetrically localised points; the greatest Lmax of the two values is preferred. The derived values are used to determine a degree of manifestation of local hyperthermia or the absence thereof and to diagnose a tumour nature. If Qmax is - 2.0°C and more, and Rmax is - 2.5°C and more, if the symmetrical points are localised the same or if Qmax is - 2.0°C and more, and Lmax is - 2.8°C and more with the symmetrical points localised differently, the manifested local hyperthermia is stated, and a malignant breast pathology is diagnosed; while if Qmax is less than 2.0°C and Rmax is less than 2.5°C or Lmax is less than 2.8°C, the absence of local hyperthermia is stated, and a benign breast pathology is diagnosed.

EFFECT: method enables differentiating the benign and malignant breast pathologies.
