应用多层螺旋CT与钼靶摄影对乳腺癌的诊断与研究

Application of Multi-sliral CT and X-ray in Breast Cancer image Diagnosis

目的:探讨多层螺旋CT及钼靶摄影在乳腺癌诊断中的应用价值。方法:回顾性分析经病理证实的71例乳腺癌平扫、增强及重建图像。结果:71例乳腺癌均为肿快型,57例表现为不规则形,48例边缘见毛刺,8例皮肤改变,4例皮肤内陷,周围侵犯12例,32例见腋窝淋巴结,纵隔淋巴结及肺内转移。增强后肿快强化明显,CT值升高(18——83)HU;并行重建使肿块周边结构呈立体显示。结论:多层螺旋CT检查在乳腺癌定性诊断中有一定的应用价值。

Objective：To discuss the application value of the multi-slice spiral CT indiagnosing breast cancer. Methods：The images of scanning, enhancing and reconstruction were analyzed in 71 cases of breast cancer proved by clinical pathology. Results：All the 71 cases were the type of mass. The shapes of the tumor in 57 cases were irregular, burrs can be seen in 48 cases, the skin in 8 cases changed, the nipples in 4 cases sunk, the tissue around the tumor was invaded in 12 cases; The CT value of the tumor rised greatly after enhancement, theranges of value was form 18 to 85 HU. Axilla lumph nodes were detected in 32 cases, We can find the lumph node in mediastinum and lung metasis; The tumor and tissue around it can be shown well in multi-orientations through images reconstruction. Conclusion：The multi-slice spiral CT has the evident application value in pualitative diagnosing breast cancer.
