Author Information
Author(s): Kim Sunhee, James M. Mountz
Primary Institution: Children's Hospital of Pittsburgh and The University of Pittsburgh Medical Center
Conclusion
Ictal SPECT has the highest diagnostic sensitivity for both temporal and extratemporal lobe epilepsy, while PET is known to have high sensitivity for the evaluation of extratemporal lobe epilepsy.
Supporting Evidence
- Ictal SPECT has a sensitivity of 97% to 100%, which is higher than interictal SPECT.
- PET is known to have high sensitivity for evaluating extratemporal lobe epilepsy.
- Quantitative image analysis can improve diagnostic accuracy of SPECT and PET.
Takeaway
This study looks at how different brain imaging techniques help doctors find the cause of seizures in people with epilepsy. It shows that one method, called SPECT, is really good at finding where the seizures start.
Methodology
The review discusses the principles of SPECT and PET imaging, including tracer properties, acquisition protocols, and diagnostic performance.
Limitations
The study does not provide specific limitations but mentions challenges in accurately localizing seizure foci.
