Abstract:
Objective:To evaluate the consistency between architectural distortion（AD）observed on coronal images in three-dimensional ultrasonography（3D-US）and full-field digital mammography（FFDM），and to analyze the influencing factors of the presence of AD on 3D-US coronal images.Methods:A retrospective study was conducted on 96 female patients（97 lesions）with AD identified via FFDM that examined at Affiliated Hangzhou First People's Hospital，School of Medicine，Westlake University from January 2019 to December 2021，all of which with corresponding 3D-US results. Kappa analysis was used to assess the consistency between AD on 3D-US and FFDM.The differences of the lesion characteristics on FFDM（glandular density，presence of calcifications，and degree of distortion），3D-US features（number of lesions，presence of mass or non-mass lesions，and skipping sign in coronal images），clinical pathological characteristics（age，location，and pathology）between groups with AD and without AD in 3D-US were compared. Multivariate Logistic regression was used to identify the influencing factors.Results:Among the FFDM-identified AD lesions，62（63.92%，62/97）lesions showed AD on 3D-US coronal images，including 30 malignant lesions（48.39%，30/62）；35（36.08%，35/97）lesions without AD on 3D-US，in which 4（11.43%，4/35）were malignant. The consistency of distortion degree between FFDM and 3D-US was moderate（Kappa=0.455， P<0.001），with no statistically significant difference（ χ2=2.882， P=0.143）. The probability of malignancy was higher in typical AD compared to atypical AD. The comparisons of age，location，number of lesions，presence of skipping sign in 3D-US，breast density，and presence of calcification in the lesion showed no statistically significant differences between the groups with and without AD（all P >0.05）.The pathological results of malignancy，presence of lesions in 3D-US（mass and non-mass lesions），and the degree of distortion in FFDM showed statistically significant differences（all P < 0.05）. The multivariate Logistic regression analysis indicated that there were no independent risk factors for the appearance of AD in 3D-US（all P > 0.05）. Conclusions:In breast FFDM AD lesions，the incidence of 3D-US coronal plane AD was 63.92%，and the consistency between the degree of distortion in FFDM and 3D-US was moderate. The probability of malignancy is higher with typical AD. Pathological malignancy，presence of lesions in 3D-US（both mass and non-mass lesions），and typical AD in FFDM are more likely to correspond with AD in the coronal.
