- FIGURE 1.
AIS (Asena GH-Alaris) pump containing radioactive dose, fixed inside lead-shielded box (A). Pump is connected to patient's forearm via pressure extension line filled with heparin and normal saline. Pump is also connected to pump-control module, which activates pump to inject precise volume of tracer to allow for radioactive decay. At electroencephalogram technicians’ workstation (B), technician supervises V-EEG of patient and is ready to push remote-control module buttons when seizure is detected.
- FIGURE 2.
Continuous line shows theoretic error in dose administration (in %) using MI at different times (over 4-h period at 30-min intervals) after tracer preparation. Dashed line shows error confidence interval using AI.
- FIGURE 3.
TI in seconds for each patient: 29 patients injected using MI (TMI = TSI + Tmanual) (A) and 27 patients injected using AI (TAI = TSI +Tpump) (B).
- FIGURE 4.
Percentages of successful seizure focus localization with ictal SPECT, using MI or AIS.
