Planar Scintigraphy Sensitivity and Specificity
| Western blot FRα | ||
| Scan uptake | + | − |
| + | 25 | 5 |
| − | 6 | 13 |
Physician interpretation of tumor uptake of 99mTc-EC20 from planar images (whole body and lateral head static), compared with WBA of FRα in tumor on positive–negative scale. Interpretation yielded sensitivity of 81% and specificity of 72%.
