由于骨肿瘤呈浸润性生长 ,肿瘤的周边组织反映了肿瘤的生物学行为 ,因此对骨肿瘤边界的研究是非常有意义的 ,但是以往的研究中缺乏描述这些特征的定量指标 ,而同属浸润性生长的肿瘤 ,由于浸润程度不同 ,预后也不同 .因此肿瘤诊断中 ,急需要用一个特征量来反映肿瘤组织生长的浸润程度 .通过骨肿瘤边界的分形特性研究表明 ,用形态算法获得的分形维数 ,能较好地反映骨肿瘤边缘组织的浸润性生长 ,因此它是描述骨肿瘤不同病变程度及预后情况的鲁棒性的特征参数 ,从而为骨肿瘤的深入研究开辟了新的途径 . Because bone tumors show invasive growth, the surrounding tissues of tumors reflect the biological behavior of tumors, so the study of bone tumor boundaries is very meaningful, but the previous studies lacked quantitative indicators to describe these characteristics, but the same is invasive. The growth of tumors, due to different degrees of infiltration, the prognosis is different. Therefore, in the diagnosis of cancer, it is urgent to use a characteristic amount to reflect the extent of tumor tissue infiltration. Through the fractal characteristics of the bone tumor boundary research shows that the fractal dimension obtained by the morphological algorithm The number can reflect the invasive growth of the bone tumor marginal tissue, so it is a characteristic parameter that describes the robustness of different lesions and prognosis of bone tumors, thus opening up a new way for the further study of bone tumors.
