Summary
Single photon emission computed tomography (SPECT) can assess brain blood flow and metabolism, aiding in the detection of seizure disorders. Tc-99m HMPAO SPECT shows promise for evaluating febrile convulsions.
Area of Science:
- Neurology
- Nuclear Medicine
- Medical Imaging
Background:
- Single photon emission computed tomography (SPECT) with perfusion tracers quantifies regional cerebral blood flow (rCBF).
- rCBF estimation provides indirect insights into local brain metabolism.
- SPECT may detect and monitor pathological changes in neurological conditions like seizure disorders.
Purpose of the Study:
- To review the principles and data of perfusion SPECT in seizure disorders.
- To highlight the advantages and disadvantages of perfusion SPECT.
- To present initial findings using Tc-99m HMPAO SPECT in febrile convulsions.
Main Methods:
- Review of existing literature on perfusion SPECT in seizure disorders.
- Application of Tc-99m hexamethylpropyleneamine oxime (HMPAO) SPECT in patients with febrile convulsions.
Main Results:
- Perfusion SPECT offers a method for assessing cerebral hemodynamics and metabolism.
- Tc-99m HMPAO SPECT provides initial data on its utility in febrile convulsions.
Conclusions:
- Perfusion SPECT is a valuable tool for studying cerebral blood flow in seizure disorders.
- Tc-99m HMPAO SPECT demonstrates potential for evaluating febrile convulsions, despite limitations.
