Table 2.
Ictal SPECT timings | Mean | Range |
---|---|---|
From first clinical ictal sign to tracer injection | 17 s | 1‐65 s |
From first EEG changes to injectiona | 25 s | 0‐289 s |
From start of injection to complete injection of the tracer | 13 s | 4‐46 s |
From the end of injection to seizure cessationb | 61 s | 0‐390 s |
From tracer injection to ictal SPECT | 40 min | 13‐89 min |
Injection was performed before the first EEG changes in three cases, while in one case there was no definite ictal EEG activity.
In seven cases, seizures ended before the end of injection (mean 9 s; 3‐20 s).
