血管生成是肿瘤生长和转移形成的一个基本特征。在骨转移，血管生成因子在骨髓腔肿瘤和骨细胞，导致局部骨质破坏的互动以及对肿瘤细胞增殖的关键。我们的目标是开发一个模型实验骨转移，可以在体内的血管生成骨骼病变，使用非侵入性的成像技术评估。 为此目的，我们注入腹壁浅动脉，这就排除了1比各自的后腿的其他身体部位的生长转移中的10 5的MDA-MB-231人类乳腺癌细胞。站点特定的骨转移肿瘤细胞接种后25-30天之后，开发，限制股骨远端，近端胫骨和腓骨近端1。新生血管的形态和功能方面，可以在纵向研究骨元stases使用磁共振成像（MRI），体积计算机断层扫描（VCT），超声（美国）。 MRI显示软组织的一部分，最初仅限于骨髓腔和随后而进展超过骨皮质的骨转移的形态学信息。使用动态对比增强磁共振成像（包括区域的血液量，灌注和血管通透性的DCE-MRI）的功能数据，可以得到量化2-4。在高使用形态VCT的成像分辨率骨质破坏被捕获。 MRI检查的补充，溶骨性病变可位于毗邻髓内肿瘤的生长部位。 VCT的血管造影显示造影剂应用后，在高分辨率骨转移macrovessel架构，DCE的VCT使这些病灶微循环，5,6洞察力。美国是适用评估由于骨骼病变的形态和功能特点局部骨皮质溶骨。使用B型和多普勒技术，结构和软组织转移灌注可以评价，分别。 DCE的，我们允许实时成像血管骨转移后注射微泡7。 总之，转移的多模态成像技术，包括MRI，VCT和美国提出补充信息，这些骨骼病变新生血管的形态和功能参数，在特定地点的乳腺癌骨模型。
