Movement disorders include a spectrum of entities, differing in imaging, clinical course and treatment. However, differential diagnosis between them may be challenging. Because some of these entities share similar pre-synaptic dopaminergic imaging features, other radiopharmaceuticals can add in differential and precise diagnosis. Nuclear medicine provides radiotracers and techniques which, in addition to clinical features, may be additionally helpful.    Teaching points: - List main entities known as Movement Disorders - Review the different radiopharmaceuticals and techniques in nuclear medicine, which may be potentially useful. - Illustrate the different imaging patterns of parkinsonisms on nuclear medicine, which can aid in differential diagnosis, together with clinical features  

Introduction 1. Radiotracers in movement disorders: - 123I FP-CIT - 123I Iodobenzamide (IBZM) - 99mTc HMPAO - 18-F FDG - Others: 18F-DOPA 2. Parkinsonisms - Idiopathic Parkinson´s disease - Atypical parkinsonism: o Multiple system atrophy o Corticobasal degeneration o Progressive Supranuclear palsy - Drug induced parkinsonism 3. Tremors - Essential tremor 4. Dementia: - Dementia with Lewy bodies - Parkinson´s disease cognitive decline/dementia - Parkinsonism in Alzheimer Disease
