多层CT重建技术对乳腺癌的显示及诊断价值

目的通过多层CT对乳腺癌的显示及在诊断工作中的作用进行评价,探讨多层CT在乳腺癌的诊断价值。方法收集临床、病理证实乳腺癌22例,重点分析多层CT扫描及重建对肿块本身及淋巴结显示情况。结果22例乳腺癌中表现为形态不规则、密度不均匀、边界不清肿块19例,10例显示肿块周围水肿环,肿块邻近皮肤水肿8例,乳头内陷、导管增粗6例,8例肿块胸肌相连。腋下恶性淋巴结显示12例,6例同时显示胸小肌后淋巴结,2例显示锁骨上淋巴结肿大。结论多层CT扫描及重建技术对乳腺癌性肿块内部结构、周围组织之间关系显示更为直接。对周围淋巴结尤其腋下淋巴结和胸肌后淋巴结的显示较为理想;可为影像医生和临床医生的准确诊断和正确治疗提供直观、形象、生动的图像信息。是一项简单、易行、准确的检查方法。

The diagnostic and reconstructional value of multi-slice CT in patients with breast cancer

Objective To study the diagnostic and reconstructionalvalue of multi-slice CT in patients with breast cancer. MethodsTwenty-two patients with pathologically or clinically confirmed breastcancer were studied.They were examined with multi-slice CT.Whenthe diseased breast underwent multi-plan or three dimensionalreconstruction,cancer mass and axillary lymph nodes were observedwith multi-slice CT. Results Breast cancer manifested as anirregular or spiculated mass in 19 cases out of the 22,cancer masswas surrounded with edema in 10 cases,thickening of the skin overthe cancer was found in 8 cases,and nipple retraction and ductdilatation occurred in 6 cases.Axillary lymph nodes were positivein 12 cases.In 6 cases out of the 12,lymph nodes under thepectoralis minor and above the clavicle bone were also positive.Conclusion Multi-slice CT is the best technique to obsew thevarious manifestations of breast cancer and to detect the metastases inthe surrounding lymph nodes.
