OBJECTIVE. The purpose of this study was to investigate the feasibility of diagnostic breast imaging using a flat-panel detector-based cone-beam CT system.

CONCLUSION. Imaging of 12 mastectomy specimens was performed at 50–80 kVp with a voxel size of 145 or 290 µm. Our study shows that cone-beam breast CT images have exceptional tissue contrast and can potentially reduce examination time with comparable radiation dose.

Keywords: breast neoplasm • CT radiography • mastectomy • radiation dose • specimen radiography
