In this chapter the value of structural and functional imaging for diagnosing, understanding, and managing movement disorders and their complications will be discussed. The relative roles of magnetic resonance imaging, transcranial sonography, positron emission tomography (PET), and single photon emission computed tomography (SPECT) will be contrasted. It is argued that imaging biomarkers play a valuable role in supporting diagnoses in parkinsonian disorders when these are unclear and in providing a rationale for the use of dopaminergic medications. Imaging can also detect subclinical disease activity in at-risk subjects and monitor the functional effects of putative neuroprotective and restorative therapies.
