White Matter Dysfunction and Neurotransmitter Basis Underlying the Freezing of Gait in Parkinson's Disease

iNew Medicine, EarlyView.
In the freezing of gait in Parkinson's disease, white matter shows decreased local activity but increased functional connectivity. These distinct dysfunctions are uniquely associated with specific neurotransmitter systems (GABA, dopamine, etc.), mapping a new neurochemical basis for this debilitating symptom. ABSTRACT Freezing of gait (FOG) is a severe

Evaluation of Brain Microstructural Alterations in Preschool Autism Spectrum Disorder: A Voxel‐Wise Multimodal MRI Study

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Autism Spectrum Disorder (ASD) presents with early neurodevelopmental alterations in preschool children, yet comprehensive characterization using multimodal quantitative MRI remains limited in this age group. Purpose To investigate voxel‐wise brain microstructural differences in preschool ASD through integrated analysis of cerebral ...

Association Between Gas‐Free Cerebrovascular Reactivity (CVR) and Cognitive Function in Older Adults With a High Risk for Vascular Dementia

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Vascular cognitive impairment and dementia (VCID) is the second leading cause of dementia. Cerebrovascular reactivity (CVR) is a promising biomarker for VCID. However, CVR is not commonly measured in clinical practice due to logistical difficulties in applying a hypercapnia challenge during MR imaging. Purpose To investigate whether

Clinical Validation of a Fast MRI Method to Evaluate Brain Vascular and Parenchymal Abnormalities in Sturge‐Weber Syndrome

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Sturge‐Weber syndrome (SWS) is a rare neurocutaneous disorder associated with venous capillary malformations, atrophy, and calcifications. Longitudinal imaging is limited by risks of sedation and gadolinium exposure in children.

Sonographic localisation of lymph nodes suspicious of metastatic breast cancer to surgical axillary levels

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 119-138, March 2025.
Sonographic imaging is used to identify the presence, number and location of malignant lymph nodes. Axillary lymph nodes suspicious of harbouring breast cancer metastasis can be localised to three surgical axillary levels. This paper will unpack the axillary anatomy, muscular sonographic landmarks, surgical axillary lymph node levels and the ...
