多层螺旋CT对颌骨放射性骨坏死的诊断价值

DIAGNOSTIC VALUE OF MULTI-SLICE SPIRAL CT FOR OSTERORADIONECROSIS OF JAW

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.
