目的 联系病理学变化,分析乳腺癌的CT表现和特征,评价CT扫描在乳癌及内乳和腋窝淋巴结转移诊断中的价值。方法 应用CT检查36例乳癌病人,其中浸润性导管癌15例,浸润性小叶癌1例,髓样癌5例,单纯癌8例,硬癌2例,腺癌4例,Paget氏病1例。结果 (1)乳腺癌CT表现为:圆形、椭圆形和不规则形肿块,成簇排列细小钙化点,边缘毛刺,皮肤增厚和周围脂肪间隙变形等。(2)CT有较高的密度分辨率,能检出直径<1cm的癌灶。(3)大多数乳癌血供丰富,增强扫描癌灶 有显著强化,增强前后CT值之差(△CT)>50HU。(4)CT增强后肿瘤供血血管的显示(占38.9％)对乳癌诊断有帮助价值。(5)CT有助于乳腺癌内乳和腋窝淋巴结转移的诊断。结论 CT扫描对乳腺癌的早期发现和定性诊断以及评价内乳和腋窝淋巴结有无转移都有很大的诊断价值。
Objective To correlate the pathological changes, analyze the CT features and characteristics of breast cancer, and evaluate the value of CT scan in the diagnosis of breast cancer, internal breast milk and axillary lymph node metastasis. Methods Thirty-six breast cancer patients were examined by CT, including 15 invasive ductal carcinomas, 1 invasive lobular carcinoma, 5 medullary carcinomas, 8 simple carcinomas, 2 hard carcinomas, 4 adenocarcinomas, 1 Paget’s disease. . Results (1) The CT findings of breast cancer were: round, oval and irregular masses, clustered small calcifications, marginal burrs, skin thickening and deformation of the surrounding fat space. (2) CT has a higher density resolution and can detect lesions <1 cm in diameter. (3) The majority of breast cancers are rich in blood supply, and the enhanced scanning foci are significantly enhanced. The difference in CT values before and after enhancement (△CT) is >50 HU. (4) CT-enhanced display of tumor blood vessels (38.9%) is helpful in the diagnosis of breast cancer. (5) CT is helpful in the diagnosis of breast cancer and axillary lymph node metastasis. Conclusion CT scan is of great value in the early detection and qualitative diagnosis of breast cancer and in the evaluation of the presence of internal breast and axillary lymph nodes.
