Degree of correct lateralization, by imaging test
| Imaging test | No. (%) |
|---|---|
| Group I, n = 75 | 41 (55) |
| SPECT only, n = 61 | 28 (46) |
| SPECT/CT, n = 14 | 13 (93) |
| Group II, n = 133 | 105 (79) |
| SPECT + ultrasonography, n = 62 | 47 (76) |
| SPECT/CT + ultrasonography, n = 71 | 58 (82) |
CT = computed tomography; SPECT = single photon emission computed tomography.
