The optimal timing for imaging brain tumours and other brain lesions with 18F-labelled fluoromethylcholine

Abstract

On the basis of the TACs, PET imaging with 18F-FCho starting within minutes after the administration of the tracer is preferred for the detection of brain tumours and other brain lesions. If discrimination between meningioma and other brain tumours is of concern, both 'early' and 'late' PET imaging could be helpful.
