摘要: |
目的探讨多层螺旋CT的三种重建方法对乳腺肿块性病变的显示及诊断价值.方法收集77例手术病理证实的乳腺肿块性病变,其中乳腺癌61例、乳腺良性病变16例,术前均行多层螺旋CT平扫加增强的薄层轴位扫描及MPR、MIP、VR重建,重点分析多层螺旋CT三种重建方法对肿块本身、周围结构及淋巴结的显示情况.结果61例乳腺癌中28例表现为形态不规则肿块,33例呈边缘有分叶、毛刺的类圆形肿块,34例增强后呈不均匀强化,8例与乳晕黏连,14例伴有局部皮肤增厚,5例侵犯胸壁,24例合并腋窝淋巴结转移.16例乳腺良性病变均呈类圆形肿块,其中13例边缘光滑,11例增强后呈均匀强化.结论以轴位薄层扫描信息为基础,MSCT的三种重建方法对显示乳腺肿块的位置、内部结构、与周围组织关系及腋窝淋巴结情况更为直观,为准确诊断和临床治疗提供全面、精确、直观的图像信息. |

Abstract: |
Objective To evaluate the three reconstruction methods of multi-slice helical CT in manifesting and diag- nosing breast masses. Methods 77 breast masses verified histopathologically were examined by MSCT scanning with MPR, MIP and VR reconstructions. The |
