摘　　要：目的:探讨乳腺癌术后放疗放射性肺损伤的CT表现及诊断价值。方法:分析36例乳腺癌术后放疗发生放射性肺损伤患者的CT表现。结果:36例中急性放射性肺炎8例,表现为照射野范围内斑片状、片状密度增高灶或毛玻璃样改变;中间期15例,表现介于急性期与纤维化期之间,可同时见毛玻璃样改变、斑片状实变灶及纤维条索灶;纤维化期13例,表现为照射野范围内的纤维条索灶。结论:CT检查能清晰显示乳腺癌放疗后放射性肺损伤不同时期的特征表现,具有较高的临床价值。Objective：To evaluate the diagnostic value of computed tomography in radiation pulmonary injuries in breast cancer patients treated by postoperation radiotherapy. Method：36 cases of radiation pulmo- nary injuries in breast cancer patients treated by postoperation radiotherapy were reviewed retrospectively. Result： In 36 patients of first examination, 8 patients represent acute radiation-induced pneumonia, acute radiation-induced pneumonia stage represents high -density image and ground- glass opacity in irradiation area;15 cases are in transition stage, represents strip lard patch image and ground glass opacity in irradiation area; 13 cases are in fibrosis stage, represents thick strip in the area. Conclusion： Computed tomography can accurately show the characteristic of radiation pulmonary injuries in breast cancer patients treated by postoperation radiotherapy in different stage, It＇ s worth widely wsing in clinical practice.
