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 improve the understanding of CT images of early radiation-induced liver injury. Methods A retrospective review of 7 cases of 3-D conformal radiotherapy abdominal tumor patients complete image data to observe the patient before and after radiotherapy liver CT image changes. Results CT scan was performed after radiotherapy. Five patients underwent liver delineation as clearly demarcated low-density changes. Two patients with steatotic fatty degeneration showed clearly demarcated high-density changes. Enhanced CT examination, the normal liver and liver cirrhosis of the dynamic performance of radioactive lesions different. Conclusion The changes of CT images in patients with radiation-induced liver injury are related to the primary liver diseases.
