应用三维超声重建成像诊断乳腺癌

背景与目的：评价三维超声重建成像在乳腺癌诊断中的应用价值。材料与方法：采用LOGIQ 7型彩色超声诊断仪。对经病理证实的48例乳腺癌患者进行二维及一维超声成像检查。结果：三维超声重建成像对乳腺癌肿块周边浸润层次、彩色血流分布情况等，明显高于二维超声检查。三维超声重建成像显示乳腺癌肿块大小形态，与皮肤、胸肌、胸壁等周边组织关系较明确，对乳腺癌血流分布情况显示清晰。结论：三维超声重建成像能更充分地表现肿瘤的形态结构、毗邻关系及血流分布情况，有助于乳腺癌诊断和临床评估。

Application of Three- Dimensional Ultrasonography in Breast Cancer

BACKGROUND&AIM: To evaluate the value of three-dimensional ultrasonography(3D-US)in breast cancer diagnosis. MATERIAL AND METHODS: The LOGIQ7sonography imaging system was used to perform conventional two-dimensional and three-dimensional ultrasonographic examinations.The study population consisted of48randomized breast cancer patients. RESULTS: The positive rate of the breast cancer in3D-Us was higher than that of2D-US,even in the tumor's relation with adjacent tissues and the blood distribution.3D-US could stereoscopically show the tumor's shape,the relations between the tumor and the skin,chest muscle,chest wall,etc.And it could clearlg show the network of blood vessels of the cancer. CONCLUSION: 3D-US could display breast cancer's structure,adjacent relations and blood vessels because of its high sensitivity.It is helpful for the diagnosis and evaluation of breast cancers.
