MOVEMENT DISORDERS CLINICAL PRACTICE, cilt.4, sa.6, ss.907, 2017 (ESCI)
In the last decades, transcranial sonography has been proven to be a useful imaging method in the field of movement disorders. In the clinical routine, structures that are easy to evaluate are the mesencephalic brainstem, including the mesencephalic midline raphe and the substantia nigra in the mesencephalic scanning plane; and the third ventricle, lateral ventricles, basal ganglia, and thalamus in the third ventricular scanning plane. In this video S1, we demonstrate the sonographic assessment of a healthy individual and a patient with Parkinson's disease, visualize how the main structures look, and discuss the assessment. In both individuals, we focus on the planimetric measurement of the substantia nigra.
