Diffusion-Weighted MRI and apparent

The Egyptian Journal of Radiology and Nuclear Medicine, 2016
The purpose of this study was to evaluate use of Diffusion-Weighted MRI (DWI) and apparent diffusion coefficient value (ADC) in differentiation of intra-medullary spinal cord masses (IMSCM).

A time-dependent diffusion MRI signature of axon caliber variations and beading

Communications Biology, 2019
MRI provides a unique non-invasive window into the brain, yet is limited to millimeter resolution, orders of magnitude coarser than cell dimensions.

Quantitative Diffusion-Weighted MRI of Neuroblastoma

Cancers, 2023
Neuroblastoma is the most common extracranial, malignant, solid tumor found in children. In more than one-third of cases, the tumor is in an advanced stage, with limited resectability. The treatment options include resection, with or without (neo-/) adjuvant therapy, and conservative therapy, the latter even with curative intent.

Cervical Spinal Cord Magnetization Transfer Ratio and Its Relationship With Clinical Outcomes in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The cervical spinal cord (cSC) is highly relevant to clinical dysfunction in multiple sclerosis (MS) but remains understudied using quantitative magnetic resonance imaging (MRI). We assessed magnetization transfer ratio (MTR), a semi‐quantitative MRI measure sensitive to MS‐related tissue microstructural changes, in the cSC and its ...

Detecting Microglial Density With Quantitative Multi-Compartment Diffusion MRI

Frontiers in Neuroscience, 2019
Neuroinflammation plays a central role in the neuropathogenesis of a wide-spectrum of neurologic and psychiatric disease, but current neuroimaging methods to detect and characterize neuroinflammation are limited.

Clinical Characteristics of Parkinsonism in HTLV‐1‐Associated Myelopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Human T‐lymphotropic virus type 1 (HTLV‐1)‐associated myelopathy/tropical spastic paraparesis (HAM/TSP) is the classic neurological manifestation of HTLV‐1 infection; however, this virus has also been associated with other neurological disorders. Concurrent parkinsonism is relatively rare and presents diagnostic challenges.

Therapy response with diffusion MRI: an update [PDF]

Cancer Imaging, 2012
The efficiency of an oncological treatment regimen is often assessed by morphological criteria such as tumour size evaluated by cross-sectional imaging, or by laboratory measurements of plasma biomarkers. Because these types of measures typically allow for assessment of treatment response several weeks or even months after the start of therapy, earlier
