AIMS Recent studies report increased echogenicity of the substantia nigra (SN) in patients with Parkinson's disease (PD) using transcranial sonography (TCS). However, the main limitation to TCS is its dependence on the sonographer's experience. Experimental software for quantitative evaluation of the echogenic SN area was thus developed by us. The aim of this study was to test the reliability o...

BACKGROUND Few studies have addressed whether abnormalities in the lenticular nucleus (LN) are characteristic transcranial sonography (TCS) echo features in patients with primary dystonia. This study aimed to explore alterations in the basal ganglia in different forms of primary focal dystonia. METHODS cross-sectional observational study was performed between December 2013 and December 2014 i...

BACKGROUND The detection of hyperechogenicity of the substantia nigra using trans cranial sonography can be predictive of the diagnosis of Parkinson Disease. AIM To report an experience with transcranial sonography for the diagnosis of Parkinson disease. Material ana METHODS One hundred sixteen patients with movement disorders were subjected to a transcranial sonography to detect the presen...

BACKGROUND AND PURPOSE To test a new contrast-specific sonography imaging method that offers visualization of the intracranial vasculature in a manner similar to that seen on angiography. MATERIALS AND METHODS Thirty patients (35 sonography studies total) were included in the study after they provided written informed consent. The patients were scanned through the temporal bone window from bo...

BACKGROUND Numerous studies have demonstrated that patients with Parkinson's disease (PD) have a higher prevalence of substantia nigra (SN) hyperechogenicity compared with controls. Our aim was to explore the neuroimaging characteristics of transcranial sonography (TCS) of patients with PD and those with PD with dementia (PDD). The correlation between the echogenicity of the SN and clinical sym...

In transcranial sonography system, we usually placed the sensor to anterior and superior of the attachment of the upper ear (posterior temporal window). Due to this limitation, we cannot obtain transcranial information from arbitrary place of the skull. Although this limitation free system is strongly required in clinical treatment, there is no discussion of the placement free transcranial sono...
