Abstract:
Objective To analyze the characteristics of breast architectural distortion(AD)in mammography,MRI,and ultrasound,and to explore the value of each imaging examination in the diagnosis of AD lesions.Methods The mammography,ultrasound,and MRI data of 46 patients(48 lesions)with AD detected by mammography were analyzed retrospectively.Based on the pathological results,the imaging characteristics of benign and malignant AD were compared.Results The morphological and central density differences between benign and malignant lesions were statistically significant.There was no significant difference in microcalcification between benign and malignant AD.On 48 breast MRI,26 lesions showed mass enhancement,17 lesions showed non-mass enhancement,3 lesions showed punctate enhancement and 2 lesions showed no enhancement.There was no statistical significance in the distribution of enhancement types.The difference in time-signal intensity curve(TIC)types between benign and malignant AD was statistically significant.There was no statistical significance in ultrasound manifestation between benign and malignant AD.Using imaging findings greater than those in the breast imaging reporting and data system(BI-RADS)4 categories as a suspected malignant diagnosis,based on pathological examination results.The area under the curve(AUC)by mammography,ultrasound,and MRI was 0.582,0.426,and 0.764,respectively,showed significant differences in diagnostic efficiency.Conclusion MRI has higher sensitivity and specificity in detecting breast AD,which significantly improves the diagnosis coincidence rate of lesions,and can provide an important basis for clinicians to make decisions on surgical treatment.
