Comparative Study of Molybdenum Target Mammography and Color Doppler Ultrasound in Breast Cancer Diagnosis

Objective:To investigate the clinical value and limitation of Molybdenum Target Mammography(breast X-ray radiography) and Color Doppler ultrasound in the diagnosis of breast cancer. Methods:Breast cancer data from 55 patients was collected in our hospital from october 2009 to December 2012. The mammography report and color Doppler ultrasound result of these cases, which were confirmed by surgery and pathological analysis for breast cancer, were analyzed retrospectively. Statistical analysis was done according to the breast Imaging and reporting System(BI-RADS) classification standard. Results: ①The coincidence rate between Molybdenum Target Mammography and pathological diagnosis is 65%; the rate between ultrasonography and pathological diagnosis is 69%. There is no significant difference(P0.05) between the above rates. The diagnostic rate with two joint applications is 89%.② The display of Microcalcification by Molybdenum Target Mammography is better than Color Doppler Ultrasound; but Color Doppler Ultrasound is better than Molybdenum Target Mammography in detection of the abnormalities of local blood vessels and blood flow. Conclusion:Our results show that Molybdenum Target Mammography and Color Doppler Ultrasound have their own strengths and weaknesses in the diagnosis of breast cancer. The combination of two diagnostic methods can significantly improve the diagnostic accuracy of breast cancer.
