Clinical History

This is a 40-year-old male patient with history of intractable seizure undergoing a Wada test. This examination is requested to evaluate brain blood flow.

Technique

While the patient was undergoing an interventional Wada test, injection of 1 millicurie of Neurolite was made with a catheter in place in the left internal carotid artery. After completion of the interventional procedure, the patient was brought to the department for SPECT brain imaging.

Findings

Injection of the Neurolite into the left internal carotid demonstrates perfusion of the left cerebral hemisphere. Perfusion of the left temporal lobe appears normal. Note is made of increased activity in the region of the left basal ganglia. In addition to perfusion of the left cerebral hemisphere there is contralateral flow to the posterior occipital region of the right cerebral hemisphere.
