目的评估CT灌注和X线摄影在对乳腺疾病诊断上的价值。方法对47例病例分别采用X线摄影和CT灌注检查后,对照病理结果。结果二者的诊断正确率分别为76.60%和87.23%,综合X线摄影和CT定性诊断正确率为95.70%,(P<0.05)。结论在病变范围、乳腺癌坏死灶的判别方面CT灌注优于X线摄影,但在对钙化灶的定性方面,X线摄影优于CT灌注。X线摄影和CT灌注具有互补性,在实际诊断中,可以联合采用,以达到更加准确的结果。
Objective To evaluate the value of CT perfusion and radiography in the diagnosis of breast diseases. Methods 47 cases were treated with radiography and CT perfusion examination, the control pathological results. Results The correct rates of the two methods were 76.60% and 87.23% respectively. The correct rate of the combined diagnosis by radiography and CT was 95.70% (P <0.05). Conclusion CT perfusion is better than X-ray in determining the extent of lesions and necrosis of breast cancer, but X-ray photography is superior to CT perfusion in the qualitative aspects of calcification. X-ray photography and CT perfusion complementarity, in the actual diagnosis, can be jointly used in order to achieve more accurate results.
