Answer

Dedicated breast CT scanners have been developed and tested in the research setting but are not yet in widespread clinical use. Its advantages are the speed of the method, comfort for the patient, absence of movement artifacts, easy standardization, and wide applicability. Dynamic contrast-enhanced CT of the breast has been found to be effective for the detection of intraductal extension of breast carcinoma and is thought to be useful in the preoperative assessment of the extent of disease prior to breast-conserving surgery. The lesions appear attenuating compared with fatty background, and they show early enhancement on arterial phase contrast-enhanced CT. [27, 32]
