摘要

Objective: To explore the diagnostic value of mammography and MRI in breast intraductal papillary carcinoma (IDPC) and compare the diagnostic value of the two methods. Methods: Collected 28 IDPC patients who underwent mammography and MRI from March 2011 to June 2019 and were confirmed by surgery and pathology. The imaging manifestations were analyzed and the accuracy of IDPC diagnosis was compared between the two methods. Results: Mammography of mammography: 24 cases showed masses, 3 cases showed asymmetric dense shadow with calcification, 1 case showed large duct dilation in the areola area, and 6 cases showed short burrs on the edge of the tumor. MRI scan: 28 cases of lesions had low signal intensity on T1WI and high signal on T2WI. 19 cases showed cystic solid masses with small nodules on the cyst wall. 25 cases showed obvious uneven enhancement lesions. The diagnostic accuracy of MRI was 89.3％. (25/28), the accuracy rate of mammography X-ray examination was 75.0％ (21/28). There was no statistical difference in the diagnostic accuracy between the two methods, and it was not statistically significant (P=0.29). The combined use of the two inspection methods has a diagnostic accuracy rate of 96.4％. The combined two methods are more valuable than relying solely on mammography (P=0.03). Conclusion: IDPC is characterized by lobular or round masses. Large cysts with small nodules may be a special MRI manifestation of this cancer. Combining mammography and MRI can further improve the diagnosis of IDPC.
