Objective:

To evaluate the clinical value of digital breast tomosynthesis (DBT) in breast cancer diagnosis and the diagnostic efficacy in breast cancer of DBT was compared with magnetic resonance imaging (MRI) and full-field mammography (FFDM).

Methods:

A total of 196 patients from Fudan University Shanghai Cancer Center

Shanghai Jiao T

ong University School of Medicine Ruijin Hospital

Peking University First Hospital were selected for FFDM

DBT

and MRI scanning. According to the Breast Imaging Reporting and Data System (BI-RADS) classification of lesions detected by FFDM

DBT and MRI

pathological results or clinical diagnosis were taken as the final diagnosis results to calculate the consistency of each image type and the final diagnosis results. The differences between each-type consistency were counted to evaluate the diagnostic efficacy of DBT technology in breast cancer. The bias evaluation of FFDM and DBT images was evaluated

including lesion visibility

lesion edge clarity

benign malignant resolution ability

and overall evaluation

to evaluate the difference between FFDM and DBT in lesion display.

Results:

The sensitivity and accuracy of DBT in breast cancer diagnosis were significantly better than FFDM. For the display of different types of lesions

DBT had a significant bias compared with FFDM. The DBT display quality of lesions was better. Although MRI was slightly better than DBT in the sensitivity

specificity and accuracy of breast cancer diagnosis

there is no statistically significant difference.

Conclusion:

The diagnostic efficacy of DBT in breast cancer is superior to FFDM and close to MRI. DBT displayed lesions better than FFDM.
