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 value of 18F-FDG PET complex CT perfusion imaging in the diagnosis of primary breast cancer. Methods 33 cases of suspected breast cancer patients underwent CT perfusion imaging and PET imaging examination, and authenticity and reliability evaluation. Results 27 cases of breast lumps confirmed by pathology as breast cancer. The sensitivity, specificity and accuracy of PET / CT in diagnosing breast cancer were 92.6%, 100% and 93.9%, respectively. Conclusions PET / CT has a high sensitivity, specificity and reliability in the diagnosis of breast cancer. As a non-invasive method, breast cancer can provide information about the metabolism and blood perfusion of breast cancer in vivo.
