Bone-related disorders of the jaw (BRDJ) include a spectrum of non-neoplastic and neoplastic lesions of the maxillofacial region that have been recently classified into fibro-osseous lesions, giant cell lesions and osseous tumours. The histopathological features of BRDJ can be similar and overlie each other. Imaging is important in order to reach a specific diagnosis. However, the appearance of BRDJ on imaging is non-specific in some cases. Computed tomography (CT) and magnetic resonance imaging (MRI) are used for accurate localisation, characterisation of the tumour matrix, delineation of the lesion extension and establishment of the relation of BRDJ to the surrounding structures. Imaging is usually done to detect the relationship with the adjacent surrounding vital structures and to diagnose aggressive forms, malignant transformation and associated syndromes. The correlation of the demographic findings, the location and the clinical presentations with the imaging features are important for the diagnosis of BRDJ. The proposed clinico-radiological diagnostic algorithm with CT and MRI helps a specific diagnosis to be reached in some cases.
颌骨相关疾病（BRDJ）包括一系列颌面部的非肿瘤性和肿瘤性病变，这些病变最近被分类为纤维骨性病变、巨细胞病变和骨肿瘤。BRDJ 的组织病理学特征可能相似并相互重叠。影像学在做出明确诊断方面很重要。然而，在某些情况下，BRDJ 的影像学表现是非特异性的。计算机断层扫描（CT）和磁共振成像（MRI）用于准确定位、肿瘤基质的特征、病变延伸的描绘以及 BDRJ 与周围结构的关系的建立。影像学检查通常用于检测与相邻周围重要结构的关系，并诊断侵袭性形式、恶性转化和相关综合征。人口统计学发现、位置和临床表现与影像学特征的相关性对 BDRJ 的诊断很重要。提出的 CT 和 MRI 联合应用的临床放射学诊断算法有助于在某些情况下做出明确诊断。
