Abstract
Objective To study the diagnostic value of multimodal magnetic resonance imaging in adenosis of breast and non-calcified breast cancer.Methods A total of 32 patients with adenosis of breast and 48 patients with non-calcified breast cancer diagnosed and treated in our hospital from March 2022 to March 2023 were selected as the research objects.All patients underwent multimodal magnetic resonance imaging.The MRI manifestations,diffusion-weighted imaging(DWI),dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)and DWI+DCE-MRI combined diagnostic efficacy(sensitivity,specificity,accuracy,positive predictive value,negative predictive value)of patients with adenosis of breast and non-calcified breast cancer were observed,and the consistency between the diagnostic accuracy of different diagnostic techniques for adenosis of breast and non-calcified breast cancer and the postoperative pathological results was analyzed.Results There were statistically significant differences in various enhancement patterns,internal characteristics,TIC curves and ADC values of non-mass-like enhancement in patients with adenosis of breast and non-calcified breast cancer(P＜0.05),there was no significant difference in mass-like enhancement between the two groups(P＞0.05).The sensitivity and negative predictive value of DWI+DCE-MRI combined diagnosis were higher than those of DWI diagnosis,and the specificity and positive predictive value were lower than those of DWI diagnosis(P＜0.05),there was no significant difference in sensitivity,specificity,accuracy,positive predictive value and negative predictive value between DWI+DCE-MRI combined diagnosis and DCE-MRI diagnosis(P＞0.05).The diagnostic results of DWI+DCE-MRI combined diagnosis of adenosis of breast and non-calcified breast cancer were highly consistent with the postoperative pathological results,and the consistency was higher than that of DWI and DCE-MRI(P＜0.05).Conclusion Multimodal magnetic resonance imaging has a high value in the differential diagnosis of adenosis of breast and non-calcified breast cancer,and can show significant MRI clinical features.The combination of DWI+DCE-MRI can improve the diagnostic sensitivity and reduce missed diagnosis and misdiagnosis to a certain extent,which is worthy of clinical application.关键词
