METHOD FOR PREDICTION OF THYROID GLAND NODE MALIGNANCY PROBABILITY

摘要

FIELD: medicine.;SUBSTANCE: method refers to medicine, namely to ultrasonic diagnostics, and can be used for prediction of thyroid gland malignancy probability including ultrasonography of thyroid gland node. Thyroid ultrasonography is performed. Type of echostructure of the node (EN), the presence or absence of macrocalcinates in the node (MN), the presence or absence of the rim of the Halo node (OH), the intensity of blood flow in the node (BL), the shape of the node (SN) are determined. Derived data are used to calculate a prognostic coefficient of malignancy of thyroid gland node (PC_MTGN) by the formula: PC_MTGN=Con-EN× ZnP1-MN×ZnP2-OH×ZnP3+BL×ZnP4-SN×ZnP5, where ZnP1 – (-4.3094); ZnP2 – (-4.0393); ZnP3 – (-1.9071); ZnP4 – 0.4867; ZnP5 – (-1.9915); Con – 1192.0931; Con is constant for given set; EN – type of echostructure of the node: 101 is hypoechoic, 102 is hyperechoic; MC – macrocalcinates in node: 101 – presence, 102 – absence; OH is Halo rim: 101 – absence, 102 – availability; BL is blood flow intensity in the node: 101 – high, 102 – medium, 103 – low, 104 – is absent; SN – shape of the node: 101 is incorrect, 102 is correct. If PC_MTGN is more than or equal to 0.6671, a high probability of the malignancy of the thyroid gland is predicted. If the PC_MTGN derived value is less than 0.6671, a high probability of benign of the thyroid gland nodule is predicted.;EFFECT: method provides determining the thyroid gland malignancy risk by using multidimensional modeling.;1 cl, 1 dwg, 1 tbl, 2 ex
