SPECT/CT Sensitivity and Specificity
| Western blot FRα | ||
| Scan uptake | + | − |
| + | 29 | 7 |
| − | 2 | 11 |
Physician interpretation of tumor uptake of 99mTc-EC20, compared with WBA of FRα in tumor on positive–negative scale. This interpretation yielded sensitivity of 94% and specificity of 61%.
