Summary
Single proton emission computed tomography (SPECT) aids in pinpointing epileptic foci, especially deep-seated ones undetectable by electroencephalography (EEG). This review surveys recent SPECT findings in partial epilepsy cases.
Area of Science:
- Clinical Neurology
- Neuroimaging
- Epileptology
Background:
- Single proton emission computed tomography (SPECT) is established for regional epileptic focus determination.
- Deep-seated epileptic foci are often missed by routine scalp electroencephalography (EEG).
Purpose of the Study:
- To survey recent findings in SPECT studies of partial epilepsies.
- To highlight the utility of SPECT in localizing difficult-to-detect epileptic foci.
Main Methods:
- Review of recent SPECT studies focusing on partial epilepsies.
- Analysis of SPECT's three-dimensional resolution power for deep brain regions.
Main Results:
- SPECT's effectiveness in identifying epileptic foci, particularly deep-seated ones.
- Demonstration of SPECT's advantage over EEG for certain epilepsy types.
Conclusions:
- SPECT is a valuable tool in clinical epilepsy for regional focus determination.
- SPECT's advanced resolution aids in detecting foci not visible on routine EEG.
