BACKGROUND Rabies is a zoonosis transmitted via the bites of various mammals, primarily dogs and bats. Known since antiquity, this disease may have the deadliest human fatality rates and is responsible for approximately 65,000 deaths worldwide per year. CASE PRESENTATION We report the case details of a 13-year-old boy from India belonging to a South Asian ethnicity, who presented with altered...

We report a case of serologically proved West Nile virus encephalitis. Striking bilateral hyperintensities were noted in the basal ganglia and thalami on T2-weighted and fluid-attenuated inversion recovery MR images, similar to previous accounts of the imaging findings in cases of Japanese encephalitis. Recognition of the MR imaging appearance of this entity is important because of the expandin...

We report preliminary results applying fluid-attenuated inversion-recovery (FLAIR) sequences to three patients with acute subarachnoid hemorrhage. Acute subarachnoid hemorrhage could be clearly demonstrated as areas of high signal intensity on FLAIR sequences in all patients. These preliminary results suggest that with FLAIR sequences one could reliably diagnose acute subarachnoid hemorrhage.

We describe fluid attenuated inversion recovery sequence MRI and proton MR spectroscopy appearances of the brain in a 7-year old Saudi boy who presented with the clinical features of Hallervorden-Spatz disease to King Fahad National Guard Hospital, Riyadh, Kingdom of Saudi Arabia.

A 61-year-old man experienced severe bilateral posterior ischemic optic neuropathy after cardiac bypass surgery. Routine magnetic resonance imaging sequences were normal, but diffusion-weighted and fluid-attenuated inversion recovery (FLAIR) sequences showed abnormal hyperintensity within both intra-orbital optic nerves. This imaging abnormality has not been previously reported in this setting.

We present findings on MR imaging in 5 patients with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). In the literature, early atrophy of the superior vermis as well as progressive atrophy of the cerebellar hemispheres and cervical cord was described. We found linear hypointensity on T2 and T2 fluid-attenuated inversion recovery-weighted images in the pons in all of our 5 pat...

Time-lapse seismic data are widely used for monitoring timevariant subsurface changes. Conventional analysis provides qualitative information by comparing results from consecutive surveys, whereas waveform inversion can retrieve quantitative estimates of reservoir properties through seismic waveform fitting. The quantitative evaluation of the physical parameters obtained by waveform inversion a...

BACKGROUND AND PURPOSE Transient or minor ischemic stroke is associated with an early risk of deterioration. Baseline perfusion-diffusion mismatch may predict clinical deterioration and infarct growth in this population. METHODS High-risk transient ischemic attack and minor stroke (National Institutes of Health Stroke Scale ≤3) subjects were prospectively enrolled and imaged with MRI within 2...
