Transcranial Magnetic Stimulation

Journal of Psychiatric Practice, 2017
Transcranial magnetic stimulation is a technique that allows the induction of electrical current in the superficial brain tissue, by means of a rapidly changing magnetic field. It is a noninvasive technique which may be safely applied to awake and collaborating humans.

Transcranial Sonography in Ataxia

2010
Transcranial sonography (TCS) identifies basal ganglia alterations in extrapyramidal movement disorders such as Parkinson's disease or dystonia. Although only rarely reported, TCS also reveals signal alterations of basal ganglia in several forms of hereditary and nonhereditary ataxia.

Transcranial Sonography in Dystonia

2010
The cause of idiopathic dystonia is not entirely elucidated. In the pathophysiological model of dystonia, the basal ganglia play a major role, mainly putamen, globus pallidus internus, thalamus, and cortex. However, using conventional structural neuroimaging methods, no specific alterations could be detected in this area. Using transcranial sonography (

Transcranial magnetic stimulation

2019
This review presents the neurophysiologic principles and clinical applications of transcranial magnetic stimulation (TMS) and other related techniques of noninvasive cortical stimulation. TMS can serve various purposes for diagnosis or treatment. Regarding diagnosis, TMS is mainly dedicated to the recording of motor evoked potentials (MEPs).

Transcranial Doppler Series Part II: Performing a Transcranial Doppler

American Journal of Electroneurodiagnostic Technology, 2009
Because of its portability, low cost, and quick, noninvasive nature, transcranial Doppler (TCD) has become a widely utilized exam to evaluate the basal cerebral arteries for various disease processes. The test is considered a "blind" and very difficult study by most vascular labs.

Transcranial Sonography In Depression

2010
Transcranial sonography, which displays tissue echogenicity of the brain through the intact skull, reveals reduced echogenicity of the brainstem raphe (BR) as a characteristic finding in unipolar depression and in depression associated with Parkinson's or Wilson's disease, but in general not in healthy adults, bipolar affective disorders, schizophrenia,

Transcranial Doppler in children

Pediatric Radiology, 2011
Transcranial Doppler US, a non-invasive tool for evaluating the cerebral arteries, has evolved significantly during the last two decades. This review describes the practical procedure, and summarises and illustrates its established and "work-in-progress" indications in children. Indications for a transcranial Doppler US examination include, but are not

Transcranial Doppler Ultrasonography

Neurosurgery Clinics of North America, 1994
Transcranial Doppler ultrasonography is an extremely useful adjunct in neurosurgical intensive care. Continuous improvements in TCD equipment as well as computer software have improved examination success and also vessel identification. Recent expanding applications of TCD have also allowed the study of disorders of control of the cerebral circulation.

Transcranial Sonography—Anatomy

2010
Transcranial B-Mode sonography (TCS) allows quick, reliable, and inexpensive depiction of a number of brain structures, which may help in the diagnosis and differentiation of various movement disorders. In the following sections the anatomical structures in three standardized TCS planes (Section I) and the methods of measurement and typical ...
