Eighteen patients with abnormalities of the mandible and two normal volunteers were studied with MRI. Correlation was made with MR, CT, plain X-rays, clinical examination, and surgical findings when possible. In primary tumors of the mandible, MR was able to differentiate between solid and cystic lesions. In the cases of secondary invasion of the mandible by malignant tumors, MR was able to demonstrate replacement of the normal high signal bone marrow by low signal tumor. In some cases, the extent of marrow involvement shown on MR and confirmed at surgery was significantly underestimated by clinical examination, plain films, and CT. From this limited experience, it appears that MR may play an important role in imaging pathology of the mandible.
对18例下颌骨异常患者和2名正常志愿者进行了磁共振成像（MRI）研究。尽可能将MRI结果与磁共振成像（MR）、计算机断层扫描（CT）、普通X线片、临床检查及手术结果进行对比。在下颌骨原发性肿瘤中，MR能够区分实性和囊性病变。在恶性肿瘤继发侵犯下颌骨的病例中，MR能够显示正常高信号骨髓被低信号肿瘤取代。在某些病例中，临床检查、平片和CT显著低估了MR显示并经手术证实的骨髓受累范围。基于这一有限的经验，MR似乎在下颌骨成像病理学中可能发挥重要作用。
