目的 :对比分析放射性肺炎的常规X线和CT特点 ,评价CT对本病的诊断价值。方法 :回顾性分析 46例放射性肺炎的常规X线和CT表现。结果 :放射性肺炎的典型表现为照射野内散在分布小灶性渗出性病变 ;形态与照射野一致的大片密度增高影 ;肺间质增厚和 (或 )肺纹理增粗 ;边缘锐利清晰的纤维化影或肺不张 ,该表现多见于中后期。结论 :CT对放射性肺炎的诊断明显优于X线 ,且两者对该病的临床治疗和预后判断具有重要意义。
OBJECTIVE: To compare and analyze the characteristics of routine X-ray and CT of radiation pneumonitis and evaluate the diagnostic value of CT in this disease. Methods: The routine X-ray and CT findings of 46 cases of radiation pneumonitis were retrospectively analyzed. Results: The typical manifestation of radiation pneumonitis is diffuse distribution of small focal exudative lesions in the field of radiation; large areas of density hyperplasia consistent with the irradiation field; pulmonary interstitial thickening and / or pulmonary thickening; sharp and sharp fibrosis Film or atelectasis, the performance more common in the late. Conclusion: The CT diagnosis of radiation pneumonitis is superior to X-ray, and both of them have important significance in the clinical treatment and prognosis of the disease.
