PET/CT复合功能成像系统诊断乳腺癌

Qualitative analysis of FDG uptake and blood perfusion by PET/CT in breast cancer

目的评价18F-FDG PET复合CT灌注成像诊断原发性乳腺癌的价值。方法对33例疑似乳腺癌病人行CT灌注成像和PET成像检查,并进行真实性和可靠性评价。结果27例乳房肿块经病理证实为乳腺癌。PET/CT诊断乳腺癌的敏感度、特异度和精确度分别为92.6%、100%、93.9%。结论PET/CT诊断乳腺癌有着较高的敏感度、特异度和可靠性,作为一种非侵袭性检查方法,可提供乳腺癌在活体内的代谢和血流灌注信息。

Objective To evaluate the use of PET/CT in the diagnosis of breast cancer. Methods In this study ,33 patients with suspicious breast tumor underwent PET/CT imaging. The images of the breast were analyzed for qualitative assessment of increased tracer uptake and blood perfusion with PET/CT. Results Among 27 cases with pathology proved breast cancer, 25 was judged as PET/CT positive,2 was false-negative. Sensitivity, specificity and accuracy of PET/CT in identifying breast cancer were 92.6% , 100% ,93.9%. Conclusion PET/CT is a reliable and sensitive measure in the diagnosis of breast cancer in vivo.
