Abstract    Objective    To investigate the value of elastosonography and molybdenum X-ray photography in the diagnosis of breast diseases. Methods    From March 2009 to August 2010, 65 female patients with 72 lesions in breast were examined with elastosonography and molybdenum X-ray photography in Zouping Family Planning Maternal and Child Health Service of Binzhou City of Shandong Province.Pathology was used as the golden diagnosing criterion. The accuracy of elastosonography and molybdenum X-ray photography for diagnosing breast diseases was compared. Results Pathological examination showed 53 nodules were benign and 19 nodules were malignant.The sensitivity, specificity and Youden index of elastosonography were 84.2%,96.2% and 0.804 respectively.Those of molybdenum X-ray photography were 68.4%,92.4% and 0.608 respectively. Conclusion    The accuracy of elastosonography is much higher than that of molybdenum X-ray photography.The combinative use of elastosonography and molybdenum X-ray photography can elevate the accuracy for differentiating the benign from malignant breast tumours.
