摘要
目的:探讨多层螺旋CT对颌骨放射性骨坏死(ORNJ)的诊断价值。方法:回顾性分析27例经手术、病理证实为ORNJ的CT表现。结果:ORNJ在多层螺旋CT上主要表现为局限性骨质破坏和死骨形成。结论:多层螺旋CT能清楚的显示ORNJ病灶的位置、形态、病灶内的死骨形成、有无骨膜反应及软组织肿块形成等,对ORNJ的诊断及鉴别诊断有重要的价值。
Objective:To investigate the diagnostic value of multi-slice spiral CT for osteoradionecrosis of jaws (ORNJ). Methods:The CT ifndings of 27 cases ORNJ that were conifrmed by surgery and pathology were retrospectively analyzed. Results: The main CT ifndings of ORNJ were limited bone destruction and sequestration.Conclusions:Multi-slice spiral CT can clearly display location and appearance of lesions, sequestration, periosteal reaction and soft tissue mass formation. So multi-slice spiral CT has important value for diagnosis and differential diagnosis of ORNJ.
