Diagnosis Significance Of Single High Frequency Ultrasonography And Mammography And Their Combined Examination On Breast Cancer

Objective: to evaluate the diagnosis significance of single high frequency ultrasonography and mammography and their combined examination on breast cancer. Methods: 352 female patients diagnosed with breast cancer were selected in this study from The First Affiliated Hospital of Zhengzhou University from January 2012 to December 2014. Among them, 124 cases only received high-frequency ultrasonography examination, 102 cases only mammography, and the rest 126 patients received both. Results: the patients with single mammography examination had the coincidence rate of 79.4%, misdiagnosis rate of 10.8%, and missed diagnosis rate of 9.8%; the patients with single high frequency ultrasonography examination had the coincidence rate of 83.9%, misdiagnosis rate of 9.7%, and missed diagnosis rate of 6.5%; and patients with combined examination had the coincidence rate of 89.7%, misdiagnosis rate of 6.3%, and missed diagnosis rate of 4.0%. The differences of the detection rate and missed diagnosis rate between the combination diagnosis and single examinations had statistical significance, but the misdiagnosis rate had not. Conclusion: Mammography and high frequency ultrasonography have their own advantages, and it is complementary to adopt both in the diagnosis of breast cancer, which can significantly improve the detection and accuracy rate, and also decrease the misdiagnosis and missed diagnosis rate.
