比如

Journal of Nuclear Medicine Vol. 47 No. 8 1255-1259

All patients underwent successful surgery, and pathologic examination confirmed nodes positive for metastasis in 32 patients and 82 of 397 excised nodal groups.

The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of PET/CT were 93.90% (77/82 nodal groups), 92.06% (290/315), 92.44% (367/397), 75.49% (77/102), and 98.31% (290/295), respectively

这也就是为什么你会看到很多文献说PET-CT特异性高的原因--不同的人群。
