Glioma models have provided important insights into human brain cancers. Among the investigative tools, MRI has allowed their characterization and diagnosis. In this study, we investigated whether diffusion MRI might be a useful technique for early detection and characterization of slow-growing and diffuse infiltrative gliomas, such as the proposed new models, LN-2669GS and LN-2540GS glioma sph...

background : magnetic resonance imaging (mri) offers higher diagnostic accuracy for brain lesions caused by heroin abuse compared to compute tomography (ct) scan. these lesions have a low signal on t1-weighted (t1w) images and a high signal on t2-weighted (t2w) and fluid-attenuated inversion recovery (flair) images. this study aimed to evaluate the role of diffusion-weighted mri (dwi-mri) in he...

BACKGROUND To analyze the longitudinal length accuracy of gross tumor volume (GTV) delineation with diffusion weighted magnetic resonance imaging for esophageal squamous cell carcinoma (SCC). METHODS Forty-two patients from December 2011 to June 2012 with esophageal SCC who underwent radical surgery were analyzed. Routine computed tomography (CT) scan, T2-weighted MRI and diffusion weighted m...

BACKGROUND AND PURPOSE Neonatal arterial ischemic stroke occurs in > or =1:4000 births. Many children experience motor deficits but acute predictors of outcome are lacking. Diffusion-weighted MRI changes in descending corticospinal tracts remote from arterial ischemic stroke may represent pre-Wallerian degeneration. We verify and quantify this signal and correlate it with motor outcome. METHO...

OBJECTIVES To evaluate the sensitivity of diffusion weighted magnetic resonance imaging (MRI) for the diagnosis of clinically suspected reversible ischaemic deficits of the brainstem. METHODS A total of 158 consecutive patients presenting with acute signs of brainstem dysfunction were investigated using EPI diffusion weighted MRI within 24 hours of the onset of symptoms. High resolution T1 an...

BACKGROUND MRI changes due to status epilepticus (SE) often suggest a combination of cytotoxic and vasogenic edema, but it is unclear why only certain patients have MRI changes. OBJECTIVES To determine the frequency of MRI changes due to SE and the associated patient characteristics. METHODS We reviewed records for demographics, medical history, and MRI changes attributable to seizures of a...

In recent years, diffusion-weighted magnetic resonance imaging (DW-MRI) has been increasingly used to explore the relationship between white matter structure and cognitive function. This technique uses the passive diffusion of water molecules to infer properties of the surrounding tissue. DW-MRI has been extensively employed to investigate how individual differences in behavior are related to v...
