objective to study the X line each other as for the effect and the diagnostic value of clinical diagnosis of breast tumor. Methods select 82 cases of breast tumor patients of our hospital as the research object, using the X line each other like technology and X-ray photograph target photography technology to diagnosis of patients, and compare the imaging characteristics and diagnosis of efficient. Results X-ray mammography with X-ray photography each other like in the clinical examination of breast tumor detection rate of 100%, but in benign lesions and malignant lesions detection sensitivity specificity are different, the X line each other like technical detection sensitivity (91.6%) and specificity (94.6%) were significantly superior to X-ray mammography photography (sensitivity and specificity were 83.3% and 87.8%, respectively), and a significant difference, P < 0.05, has more significance. Conclusion X-ray each other like technology, high resolution, can be more clearly shows the internal structure of the tumor, breast microcalcification, high sensitivity, higher accuracy in the diagnosis of breast tumor, worthy of clinical popularization and application.
