Objective: To compare the diagnostic value of color Doppler ultrasonography, mammography and magnetic resonance imaging (MRI) in the diagnosis of negative breast cancer.Methods: From September 2011 to December 2017, 91 patients with nonpalpable breast cancer due to breast pain, breast lumps and other symptoms in our hospital were selected, including 30 patients with malignant tumors (malignant group) and 61 patients of benign lesions (benign group), their diagnostic features of all patients with color Doppler ultrasound, mammography and MRI were recorded.Results: Compared with the benign group, mammography in the malignant group mostly showed dense glands, tiny calcification, marginal edge burr and mass image (P<0.05). In the malignant group, 1 patient had MRI BI-RADS, 2 patients type Ⅱ curve, 8 patients type Ⅲ curve, 19 patients type Ⅳ curve. while correspondingly 30 patientshad typeⅠcurve, 27 patients type Ⅱ curve, 2 patients type Ⅲ curve and 2 patients type Ⅳ curve in the benign group, and the difference between the two groups being statistically significant (P<0.05). Mammography turned out 33 patients of malignant lesions, 58 benign lesions; color Doppler ultrasounddetermined in 35 malignant lesions, 56 benign lesions; MRIdetermined32 patients with malignant lesions, 59 benign lesions, The sensitivity and specificity of color Doppler ultrasound, mammography and MRI in the diagnosis of breast cancer were 88.5%,93.3%,88.5%,86.7%,96.7% and 100.0%.Conclusion: Color Doppler ultrasound, mammography and MRI in the diagnosis of nonpalpable breast cancer have relatively good effect, however a Combined use of the three methods can improve the effect of diagnosis of breast cancer. |
