High-Pass Filtered Phase MR Imaging to Detect Longitudinal Motor Associations of Iron Accumulation in Parkinson’s Disease
Objective: To assess whether longitudinal changes in deep grey matter nuclei iron content are associated with declining motor function in Parkinson’s disease over a period…Assessing Nigral Functional Connectivity in Parkinson’s Disease with Resting State Functional MRI
Objective: To evaluate functional connectivity of SN with basal ganglia and motor cortex in Parkinson’s disease (PD) using resting state functional MRI (RS fMRI). Background:…Clinical utility of visualization of Nigrosome-1 in patients with Parkinson’s disease
Objective: To determine the inter-rater reliability of Nigrosome-1 detection and its relation to asymmetry of clinical symptoms in Parkinson’s disease (PD). Background: Detection of Nigrosome-1…Volume analysis and localization of midbrain hyperechogenecities via TCS and MRI
Objective: We are presenting follow-up results on our previous study for 3D volumetric measurements of SN hyper-echogenicities, to differentiate PD patients from healthy controls (HC).…Substantia nigra hyperechogenicity in male methamphetamine users
Objective: To investigate the effect of sex on substantia nigra (SN) echogenicity in young-to-middle aged adults with a history of methamphetamine use. Background: The sonographic…May substantia nigra volume asymmetry be an indicator of motor asymmetry in Parkinson’s disease? A retrospective analysis
Objective: We investigated whether smaller substantia nigra is associated with worse parkinsonism on the corresponding contralateral side. Background: Degeneration of dopaminergic cells and morphologic changes…Transcranial sonography of the substantia nigra and its correlation with iron metabolism and c-reactive protein in Parkinson’s disease
Objective: To measure the echogenicity of the substantia nigra (SN) by transcranial sonography (TCS) in PD patients and discuss its correlation with iron metabolism and…Prognostic factors of motor symptoms in Parkinson’s disease using neuromelanin imaging and the relationship with (123)I-FP-CIT-SPECT
Objective: This study aimed to examine the relationship between findings of neuromelanin sensitive MRI findings and motor complications. We also examined the correlation of findings…Diagnostic value of a new coronal examination plane in transcranial nigral sonography and of additional M-mode tremor frequency determination for the differentiation of idiopathic Parkinson’s disease and essential tremor
Objective: To (1) evaluate a new coronal examination plane in comparison to the established axial examination plane for detection of nigral hyperechogenicity and (2) to…Frequency of echogenic abnormality of the substantia nigra is increased in methamphetamine users
Objective: To investigate structural abnormality of the substantia nigra (SN) in methamphetamine users using transcranial sonography (TCS). Background: Epidemiologic studies suggest that chronic use of…
