摘要
目的初步探讨PET/CT融合图像对提高PET诊断恶性肿瘤的价值。方法对103例经病理证实的恶性肿瘤患者行PET/CT显像。结果PET/CT融合图像可提高54.6%的定位准确性和20.6%的定性准确性;PET/CT发现5例PET显像阴性的恶性肿瘤复发患者。结论PET/CT图像融合不仅增加了解剖定位准确性,也提供了对非恶性氟代脱氧葡萄糖浓聚部位的鉴别,进一步提高了PET的诊断效能。
Objective lesions. Methods To explore the additional value of PET/CT fusion image in the diagnosis of malignant One hundred and three patients with proved malignant tumor performed PET/CT scanning. Results PET/CT increased the accuracy of lesion localization in 54. 6% , whereas the qualitative accuracy in 20.6%. Besides,in 5 recurrent malignant cases PET/CT revealed all lesions but negative in PET alone. Conclusion PET/CT fusion imaging was not only increase the accuracy of localization of the lesion site but also could differentiate the benign FDG uptake site, thereby promote the diagnostic value of PET alone.
