| Pinhole + SPECT/CT | |||
| Observer A | 43/61 | 70% | 64–76 |
| Observer B | 56/61 | 92% | 89–95 |

↵* Both pinhole and SPECT/CT protocols involved dual-tracer simultaneous acquisition with subtraction.
CI = exact binomial confidence interval.
Calculations are on per-adenoma basis. There were 61 adenomas in 59 patients.
