Table 1.

Sensitivity/specificity (%) summary table using per lesion analysis. Accuracy is the percentage of correct classifications [$(\text{true\hspace{0.17em}positive}+\text{true\hspace{0.17em}negative})/\text{total\hspace{0.17em}lesions}$]. For instance, for SCCBCC versus AK, $\text{true\hspace{0.17em}positive}=0.95\times 71=54$, $\text{true\hspace{0.17em}negative}=0.71\times 14=10$, $\text{total\hspace{0.17em}lesions}=71$, and $\text{accuracy}=(54+10)/71=90\%$. Best diagnostic performance with the least number of modalities and/or PCs are in bold.
