A systematic review and meta-analysis were conducted to evaluate the diagnostic accuracy
of substantia nigra hyper-echogenicity by transcranial sonography (TCS) for the diagnosis of …

This meta‐analysis aimed to evaluate the accuracy of hyperechogenicity of the substantia
nigra (SN) for the differential diagnosis of Parkinson's disease (PD) and other movement …

Background Persons with Parkinson's disease (PD) differentially progress to cognitive
impairment and dementia. With a 3-year longitudinal sample of initially non-demented PD …

Background Rigidity is one of the major manifestations of Parkinson's disease (PD), but no
quantitative and objective imaging method has been developed to measure rigidity …

Objectives This study aimed to explore the association of homocysteine (Hcy) with third
ventricle (V3) dilatation and mesencephalic area (MA) atrophy as determined by transcranial …

Objectives Transcranial sonography has been used as a valid neuroimaging tool to
diagnose Parkinson's disease (PD). This study aimed to develop a modified transcranial …

To determine the diagnostic performance of transcranial sonography (TCS) in assessing
increased echogenic area of the substantia nigra (SN) in patients with Parkinson's disease …

Non-motor symptoms (NMS) in Parkinson's disease (PD), including neuropsychiatric or
dysautonomic complaints, fatigue, or pain, are frequent and have a high impact on the …

Substantia nigra (SN) hyperechogenicity measured by transcranial sonography (TCS) is a
promising biomarker for Parkinson disease (PD). The aim of this study was to explore the …

Introduction In a retrospective magnetic resonance imaging (MRI)-based study, we showed
that changes of the third ventricle diameter (TVD) are a reliable mirror of changes of the …
