Parkinson's disease (PD) is a neurodegenerative disorder characterized by a progressive loss of monoaminergic neurons, particularly dopaminergic cell groups. Biomarkers have been developed in the last decades for the study of PD patients. Neuroimages, including Magnetic Resonance Imaging (MRI), Positron Emission Tomography (PET) and Single Photon Emission Computed Tomography are part of these biomarkers evaluated in PD. These techniques had been used for the early diagnosis of PD, for the differential diagnosis between PD and other parkinsonisms and to monitor the progression of these disorders. The ability of these images to evaluate loss of monoaminergic activity and their capacity to estimate inflammatory and metabolic changes in the brain has been used. Recently the new criteria for diagnosis of PD have incorporated to PET and SPECT as useful tools in the diagnosis of this disorder. In this article, we review the utility of the neuroimages in patients with PD and some of their potential future applications.
