Abstract：Objective To comparatively analyze the accuracy of MRI, ultrasound and mammography
in the measurement of lump size in patients with breast cancer. Methods 51 cases of breast tumor
patients (53 lesions) who underwent diagnosis and treatment for breast tumors from January 2014
to June 2014 in our hospital were selected as research objects. All the selected patients underwent
preoperative mammography, ultrasound, and MRI examination to measure the size of breast lumps. The
corresponding data was recorded and compared with postoperative pathological results. The accuracy
of the three methods in determining the lump size was compared. Results The difference between
the maximum cross-sectional diameter of breast lumps obtained from mammography, ultrasound, and
MRI measurements and the results obtained by actual measurement of pathological specimens was ≤1
cm in 10 cases ( 27.8% ), 20 cases ( 55.6% ) , and 24 cases ( 66.7% ) respectively. Conclusion The
accuracy of MRI in the measurement of breast lump size was higher than the accuracy of ultrasound and
mammography. MRI is a realiable examination method in the preoperative assessment of breast tumor size.
