| Objective To study the value of CT in diagnosis of breast cancer. Methods Forty-six pathologically proved breast cancer patients underwent plain and contrast enhancement CT. The imaging features were compared with gross pathological results. Results All the 46 patients demonstrated masses on the CT images. Forty of them protruded irregularly, with lobular and spiculate boundary. Whereas 6 of them bore smooth boundary without capsule. Forty-three ones were solid masses with great enhancement (more than 45Hu), and the other 3 cases were cystic masses with little enhancement. Lymph node metastasis of axilla were detected in fourteen patients, as well as chest wall invasion in 3 patients, lung metastasis in 4 patients, skin adherence in 9 cases and nipple depression in 5 patients. Conclusion CT is useful in the diagnosis and staging of breast cancer. |
