A 54-year-old, right-handed woman presented with a 4-year history of quadriparesis. While arguing with other people, she suddenly showedweakness of the right upper and lower extremities. She underwent evaluation and conservative management with the suspicion of a cerebral infarct at the neurology department of a university hospital. However, no lesion was detected, except for a meningioma in th...

PURPOSE To evaluate the efficacy of vitrectomy combined with intravitreal injection of triamcinolone acetonide (IVTA) and macular laser photocoagulation for the treatment of nontractional diabetic macular edema (DME) refractory to anti-vascular endothelial growth factor (VEGF) therapy. METHODS Twenty-eight eyes from 28 subjects who were diagnosed with nontractional DME refractory to three or ...

BACKGROUND AND PURPOSE White matter tract-specific imaging will probably become a major component of clinical neuroradiology. Fiber tracking with diffusion tensor imaging (DTI) is widely used, but variability is substantial. This article reports the ranges of MR imaging appearance and right-left asymmetry of healthy corticospinal tracts (CST) reconstructed with DTI. METHODS For 20 healthy vol...

Canopy chlorophyll content (CCC) is closely related to crop nitrogen status, growth and productivity, detection of diseases pests, final yield. Thus, accurate monitoring in crops great significance for decision support precision agriculture. In this study, winter wheat the Guanzhong Plain area Shaanxi Province, China, was selected as research subject explore feasibility canopy spectral transfor...

Introduction and Purpose: The presence of space-occupying lesions in the brain often causes the displacement of tissue from its normal location. Accordingly, surgical resection of these lesions requires a detailed understanding of the functional and structural anatomy of the adjacent tissue. Methods such as direct electrical cortical stimulation (ECS), functional MR imaging (fMRI) and magnetoen...

Paradigm shifts are occurring across the realm of amyotrophic lateral sclerosis (ALS). In the past, we instructed medical students that ALS was solely a clinical diagnosis; that careful clinical examination raised the specter of this devastating condition, and neurophysiologic testing provided confirmation. We taught that ALS was an isolated clinical syndrome; that neuroimaging was not helpful ...

BACKGROUND There are concerns regarding early years' training for junior doctors in Trauma & Orthopaedic Surgery (T&O) in the United Kingdom. Our primary objective was to audit the clinical activities undertaken by junior doctors working in Trauma & Orthopaedic (T&O) surgery in the National Health Service (NHS) in a typical workweek. A secondary objective was to audit the clinical exposure of j...

OBJECTIVE Fractional anisotropy (FA) of the high cervical cord (C1-C2), rostral to the injury site, correlates with upper limb function in patients with chronic cervical spinal cord injury (SCI). In acute cervical SCI, this relationship has not been investigated. The objective of this study was to identify functional correlates of FA of the high cervical cord in a series of patients with acute ...

BACKGROUND AND PURPOSE Motor recovery after stroke has been shown to be correlated with both the fractional anisotropy (FA) of the affected corticospinal tract (CST) and the interhemispheric resting-state functional connectivity (rsFC) of the primary motor cortex (M1). However, the role of the restoration or enhancement of the M1-M1 rsFC in motor recovery remains largely unknown. We aimed to cl...

Diffusion tensor imaging (DTI) and diffusion tensor tractography (DTT) techniques are widely used for identifying the corticospinal tract (CST) white matter pathways as part of presurgical planning. However, mass effects in patients with brain tumors tend to cause anatomical distortions and compensatory functional reorganization of the cortex, which may lead to inaccurate mapping of white matte...
