TABLE 2.
Comparison of PET Results in Patients Who Underwent Both 99mTc-Sestamibi Imaging and 18F-Fluorocholine PET as Well as Surgery
| Finding | 99mTc-sestamibi | 18F-fluorocholine | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|
| Local | R1 | R2 | R3 | Cons | Local | R1 | R2 | R3 | Cons | |
| Correct localization | 15 | 8 | 10 | 15 | 10 | 52 | 44 | 37 | 40 | 42 |
| False-positive | 8 | 1 | 3 | 6 | 3 | 13 | 13 | 19 | 15 | 15 |
| False-negative | 36 | 49 | 46 | 38 | 46 | 4 | 3 | 4 | 5 | 3 |
| True-negative | 1 | 2 | 1 | 1 | 1 | 0 | 0 | 0 | 0 | 0 |
| CLR | 25% | 14% | 17% | 25% | 17% | 75% | 73% | 62% | 67% | 70% |
R1 = reader 1; R2 = reader 2; R3 = reader 3; Cons = consensus interpretation.
In local readings, CLR increased from 25% to 75%, and in 3 masked readings, CLR increased from 17% to 70%.
