Abstract
? Objective To compared the divergence among physical palpation,mammography and ultrasonography.Methods 155 single breast tumors from September 1997 to February 1999 were analysed,including 30 benign cases and 125 malignant cases.Measuring the largest diameter of the three different methods and comparing to the largest diameter of pathology.Results The largest diameter of pathology was 0.5～8cm (mean 2.7cm),of physical palpation was 1.0～12cm (mean 3.7cm),of mammography was 0.5～7cm (mean 2.9cm) and 0.5～4cm (mean 2.4cm) of ultrasonography.The highest correlation coefficient(r=0.93)and the smallest standard error (0.21) were obtained in mammography.Conclusions There are different degree divergences between pathological examination and other measuring methods,among them the mammography is the most accurate. 〔
