Abstract
This study investigated the feasibility of using low-dose multidetector dynamic computed
tomography (CT) scan for imaging breast. We measured the radiation dose using a phantom
at low- and standard-dose CT. To compare the image quality at low- and standard-dose
CT, we evaluated normal breasts in 57 cases. In 44 cases with breast cancer, we assessed
the staging and time-enhancement curves of breast cancer. In conclusion, the low-dose
multidetector dynamic CT scan is feasible for the evaluation of the breast, with reduced
radiation dose and with similar image quality when compared with standard-dose CT
scan. In breast cancers, low-dose dynamic CT could be used for the staging of breast
cancer before surgery.
