Imaging Nigrostriatal Dopaminergic Deficit in Holmes Tremor with 18F-PR04.MZ-PET/CT.

ABSTRACT

Holmes tremor is an infrequent clinical syndrome characterized by unilateral rest, postural, and action tremor often secondary to a brain lesion. We herein report an interesting case of Holmes tremor studied with PET and F-PR04.MZ, a new high-affinity radioligand for dopamine transporters, currently under investigation at our center. F-PR04.MZ-PET can be useful to study the integrity of the nigrostriatal dopaminergic system to improve diagnosis and therapeutic outcome in patients with Holmes tremor and Parkinson disease.
