Abstract:Objective To evaluate the actual value of PET/CT in detecting breast cancer,and make a preliminary study of its clinical significance.
Methods 33 patients with breast mass underwent PET/CT imaging and mammography.The degree of uptake of Fluorodeoxyglucose(FDG) and blood perfusion in the breast masses were respectively analyzed by semiquantitative and qualitative methods and the differences in findings of PET/CT and mammography in detecting breast cancer were compared. Results Breast cancer was diagnosed by PET/CT with sensitivity,specificity and accuracy rates of 92.6%,100% and 93.9%,respectively,and by mammography with rates of 81.5%,80% and 78.8%,respectively;in diagnostic ability,the two methods showed no significant difference(P>0.05). Conclusions In comparison with mammography,PET/CT has a higher degree of sensitivity and specificily in detecting breast cancer,and higher positive predictive value.PET/CT can provide more aspects of in vivo diagnostic information which may be useful in selecting therapeutic strategy and may supplement the inadequacies of mammography.
