Answer

No current indication exists for routine positron emission tomography (PET) scanning in patients with TSC.

PET scans may be useful when patients are undergoing evaluation as candidates for epilepsy surgery. PET scanning with the tracer alpha-methyltryptophan may have particular utility in identifying epileptogenic tubers as part of the evaluation for epilepsy surgery.
