摘要
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 .
The growth of osteoma is soakage.Osteoma' boundary organ reflect the biological behavior of osteoma.Therefore,it's important to study the fractal characteristics of osteoma boundary.However,there was lack of quantitative parameters depicting these characteristics in the past.With regard to the osteoma of soakage growth,the prognosis is different because of various degree of soakage.It is necessary to use the characteristic parameter in order to reflect soakage growth degree of osteoma.Thus,the fractal characteristics of osteoma boundary is discussed in this paper. Our results show that fractal dimension can preferably reflect the soakage growth of osteoma' boundary organ. It is a robust characteristic parameter in describing different pathological changes degree of osteoma and prognosis. This provides a new useful approach for lucubrate of osteoma.
