| 中文摘要: |
| 目的 提高对早期放射性肝损伤CT影像的认识。方法 回顾7例三维适形放疗腹部肿瘤患者的完整影像资料,观察患者放疗前、后肝脏CT影像改变。结果 放疗后CT平扫复查,5例患者受照肝脏显示为界限清晰的低密度改变,2例合并脂肪肝改变患者照射区显示为界限清晰的高密度改变。增强CT检查中,正常肝脏与肝硬化肝脏放射性损伤的动态表现不同。结论 放射性肝损伤CT影像改变与肝脏原发疾病相关。 |

| Objective To recognize CT appearance of the early irradiation-induced hepatic injury. Methods Seven patients with abdominal neoplasms were treated with conformal radiotherapy. CT findings of hepatic images were observed. Results Low attenuation areas of liver on noncontrast CT were observed in 5 patients after delivered conformal radiotherapy. In 2 patients with fatty infiltration of the liver, CT showed relative increased density in the treatment portal. The dynamic enhanced pattern of irradiation-induced hepatic disease was different in normal liver from cirrhosis liver. Conclusion CT appearance of irradiation-induced hepatic injury is related to primary liver disease. |
