A large number of articles have reported substantia nigra hyperechogenicity in Parkinson's
disease (PD) and have assessed the diagnostic accuracy of transcranial sonography (TCS); …

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 …

Objective Numerous ultrasound studies have suggested that a typical enlarged area of
echogenicity in the substantia nigra (SN+) can help diagnose idiopathic Parkinson's disease …

Background: Essential tremor (ET) and the tremor of Parkinson's disease (PD) are the most
common tremors encountered in clinical practice. Especially in early disease stages …

Background We aimed to evaluate the utility of the combined use of cardiac 123I-
metaiodobenzylguanidine (MIBG) scintigraphy, olfactory testing, and substantia nigra (SN) …

Purpose One of the anatomical hallmarks of Alzheimer's disease (AD) is the atrophy of the
medial temporal lobe (MTL), yet cost-effective and broadly available methodological …

The hyperechogenicity of the substania nigra (SN) has been established as a valid finding in
patients with Parkinson's disease (PD), probably caused by an increased tissue iron …

Background: Numerous studies have demonstrated that patients with Parkinson's disease
(PD) have a higher prevalence of substantia nigra (SN) hyperechogenicity compared with …

Background and purpose Transcranial sonography (TCS) of the brain parenchyma is used
to visualize alterations in the substantia nigra (SN) and it is applied for early diagnosis of …

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 …
