| Planar and SPECT/CT imaging | No. of DTC patients (n = 117) |
|---|---|
| Concordantly negative | 58 (49.6%) |
| Concordantly positive | 52 (44.4%) |
| With same number of foci on planar imaging and SPECT/CT | 42 (35.9%) |
| With higher number of foci on SPECT/CT than on planar imaging | 10 (8.5%) |
| Discordant | |
| Planar imaging negative and SPECT/CT positive | 7 (6.0%) |
