摘要 目的探讨64层螺旋CT重建技术对乳腺肿瘤的诊断价值。方法20例经病理证实乳腺肿瘤患者均经64层螺旋CT扫描,然后进行0.6mm薄层及MPR、VR、SSD等重建,对肿瘤重建图像的形态特征及其血管、淋巴结显示情况进行分析。结果乳腺癌表现为不规则软组织肿块,边缘毛糙,有毛刺。其中呈分叶状4例,皮肤增厚乳头内凹3例,肺内转移及锁骨上淋巴结肿大1例,腋窝淋巴结肿大2例;纤维腺瘤表现为肿块边缘光整,密度均匀,境界清晰;囊肿表现为境界清晰类圆形低密度影,CT值为10~30HU;导管乳头状瘤表现为导管位置小结节状肿块,相应乳腺导管迂曲扩张。结论64层螺旋CT的薄层重建及后处理提供更多显示乳腺肿瘤的图像信息,有助于病变定性诊断。
