乳腺癌的CT 诊断

目的 评价乳腺癌CT诊断价值。方法 46例经手术病理证实的乳腺癌患者，行CT平扫和增强扫描。将扫描结果与大体病理标本相对照，研究其CT表现。结果 46例乳腺癌CT扫描均可见肿块。40例乳腺肿块边界不光整，有分叶和毛刺；6例肿块边界尚光整，但无包膜。43例平扫为实性肿块，增强扫描CT值平均升高45Hu以上；3例为囊性肿块，增强扫描CT值无明显升高。46例中，14例合并腋窝淋巴结转移，3例侵犯胸壁，4例并肺转移，9例与皮肤有粘连，5例乳头凹陷。结论 CT检查有助于乳腺癌的定性和术前分期。

CT Diagnosis of Breast Cancer

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. [
