Diagnostic value of MRI and mammography in ductal carcinoma in situ of the breast

Abstract

Objective To investigate the diagnostic value of MRI and molybdenum target in ductal carcinoma in situ (DCIS). Methods From June 2014 to June 2018, 58 patients diagnosed as DCIS in Heji Hospital Affiliated to Changzhi Medical College were chosen.MRI and mammography were performed, and the diagnostic potency of the two methods was observed. Results The coincidence degree of molybdenum target X-ray and MRI diagnosis: the coincidence coefficient kappa=0.452 of molybdenum target X ray and MRI showed that the two diagnostic methods were in general anastomosis.The diagnostic consistency of different examination methods: the diagnostic consistency of molybdenum target combined with MRI (96.6%) was significantly higher than that of molybdenum target X(82.8%), the difference was statistically significant (χ2=5.95, P 0.05). Conclusion Molybdenum target and MRI in diagnosis of DCIS have their own characteristics.Combined application can improve the diagnostic effect.
