The majority of benign bone lesions can be evaluated adequately using conventional radiologic techniques. However, it is not always possible to differentiate reliably between different types of benign bone lesions on the basis of plain film appearances alone. Dynamic computed tomography (CT) scanning provides a means for further characterizing such lesions by assessing their degree of vascularity. Thus, it may help in distinguishing an osteoid osteoma, which has a hypervascular nidus, from a Brodie's abscess, which is avascular. Dynamic CT scanning may also help in the differentiation between a fluid-containing simple bone cyst, which is avascular, and other solid or semi-solid benign bone lesions which show varying degrees of vascularity. However, because of the additional irradiation involved, dynamic CT scanning should be reserved for evaluation of selected patients with benign bone lesions in whom the plain film findings are not definitive and in whom the CT findings may have a significant influence on management.
大多数良性骨病变可以通过传统放射学技术进行充分评估。然而，仅根据平片表现可靠地区分不同类型的良性骨病变并不总是可行的。动态计算机断层扫描（CT）通过评估病变的血管化程度，为进一步表征此类病变提供了一种方法。因此，它可能有助于区分具有高血管化瘤巢的骨样骨瘤和无血管的布罗迪脓肿。动态CT扫描还可能有助于区分无血管的含液性单纯骨囊肿与显示不同程度血管化的其他实性或半实性良性骨病变。然而，由于涉及额外的辐射，动态CT扫描应仅用于评估平片表现不明确且CT结果可能对治疗有重大影响的选定良性骨病变患者。
