Transcranial sonography in movement disorders.
BACKGROUND Transcranial sonography (TCS) in the B-mode has the ability to image, infratentorial and supratentorial brain structures. For this reason, it has potential use in the diagnosis and differential diagnosis of various intracranial pathologies. METHODS AND RESULTS The authors reviewed the contribution of TCS to the differentiation of a number of neurodegenerative diseases: in parkinson...
متن کاملTranscranial sonography (TCS) of brain parenchyma in movement disorders: quality standards, diagnostic applications and novel technologies.
Transcranial B-mode sonography (TCS) of brain parenchyma is being increasingly used as a diagnostic tool in movement disorders. Compared to other neuroimaging modalities such as magnetic resonance imaging (MRI) and computed tomography, TCS can be performed today with portable machines and has the advantages of noninvasiveness and high resistance to movement artifacts. In distinct brain disorder...
متن کاملThe value of transcranial cerebral sonography in diagnosing neurootological disorders.
Transcranial cerebral sonography (TCCS) is a noninvasive technique that allows the clinician to detect abnormal intracranial-inner-ear fluid interactions in terms of nanoliter tympanic membrane displacements. The displacements recorded in TCCS are evoked either by the acoustic stapedius reflex or spontaneous movements generated by intracranial cardiovascular or by respiratory pressure waves tra...
متن کاملUpdate on Movement Disorders - Five New Things in Parkinson's Disease
Movement disorders is a branch of neurology that deals with disorders of the extrapyramidal system. Most such disorders have pathology in the basal ganglia or the cerebellum or their connections to the rest of the brain. Parkinson's disease is perhaps the best known example of movement disorders. Another example is Huntington's disease, which has become one of the most well studied genetic diso...
متن کامل[Transcranial sonography in Parkinson's disease].
An abnormal hyperechogenecity of substantia nigra is thought to be the most characteristic sonographic feature in Parkinson's disease (PD). However specificity and sensitivity of the ultrasound method should be refined. Using transcranial sonography, authors have examined 168 patients with different clinical signs of parkinsonism, including 99 patients with idiopathic PD, and 56 patients withou...
