METHOD OF DIAGNOSING THYROID GLAND TUMOURS BY MEANS OF MATHEMATICAL MODELLING Russian patent published in 2010 - IPC A61B5/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to surgery and is intended for diagnostics of thyroid gland tumours. Clinical-anamnestic, cytological and ultrasonic (USE) examinations of thyroid gland are carried out. During examination the following parametres are determined: ultrasonic - intranodular blood flow in nodular mass- X1, irregular contour of nodule - X2, hypoechgenecity of nodular mass - X3, calcinates in nodular mass - X4, heterogeneity of nodular mass - X5, absence of "halo: rim - X6, cytological - papillar structures - X7, intranuclear inclusions - X8, clinical-anamnestic - fast growth of nodule in thyroid gland - X9. If sign is present, value "1" is given, if it is absent - "0". On the basis of function data values Y1 and Y2 are calculated. Y1=-4.59+2.68*X1+2.66*X2+3.96*X3+1.66*X4+3.67*X5+3.97*X6+0.82*X7+1.41*X8+1.09*X9; Y2=-14.45+5.87*X1+5.36*X2+7.15*X3+3.32*X4+6_.15*X5+7.07*X6+1.69*X7+ 3.24*X8+2.51*X9, if value Y2 is greater than Y1 tumour of thyroid gland is diagnosed, if value Y1 is greater than Y2, diagnosis of thyroid gland tumour is eliminated.

EFFECT: method allows to diagnose thyroid gland tumours in pre-operation period in for selection of treatment method.
