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...

متن کاملTranscranial 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 in the evaluation of Parkinson disease.
OBJECTIVE With transcranial sonography (TS), it is possible to visualize hyperechoic signals in the sub-stantia nigra (SN) in patients with Parkinson disease (PD). Our objective was to correlate the level of echogenicity in the SN with clinical status in patients with PD. METHODS In our pilot study, using TS, we examined 15 patients with the confirmed presence of PD. Staging of the latest cli...
متن کاملTranscranial sonography of basal ganglia calcifications in Fahr disease.
Fahr disease, also known as bilateral striopallidodentate calcinosis, is a rare degenerative neurologic disorder characterized by almost symmetric calcifications of the basal ganglia, the cerebellum dentate nuclei, the thalami, and the white matter of the cerebral hemispheres. Bilateral striopallidodentate calcinosis manifests as familial autosomal dominant but also as sporadic forms. Movement ...
