This study is conducted to compare Koning Breast CT (KBCT) to mammography to evaluate if KBCT can improve the diagnostic accuracy of breast cancer. It will also compare contrast-enhanced KBCT (CE-KBCT) to mammography to evaluate if CE-KBCT can further improve the diagnostic accuracy of breast cancer.
