Optic nerve enhancement is a sign seen in different disease states; however, perineural enhancement is less common. This article presents the case of a patient with bilateral amaurosis in whom the diagnosis of giant cell arteritis was suggested by pe

In a previous study, we have shown the added value of (1) H MRS for the neuroradiological characterisation of adult human brain tumours. In that study, several methods of MRS analysis were used, and a software program, the International Network for P

Background and Purpose— Lesions in diffusion-weighted imaging (DWI-L) have been commonly described in transient global amnesia (TGA). We investigated a possible relationship between brain ischemia and TGA. Methods— Twenty-eight patients underwent

To determine the relation between baseline MRI and both conversion to multiple sclerosis (MS) and development of disability in a cohort of patients with clinically isolated syndromes (CIS).From 1995 to 1998, 175 consecutive patients with CIS underwen

Background— Growing data point toward intravenous tissue plasminogen activator (tPA) benefit after 3 hours in selected stroke patients. We aim to study safety and efficacy of tPA treatment in the 3- to 6-hour window using multimodal transcranial Do

Optic neuritis presentations are thought to have a better prognosis. The aim of our study was to compare conversion to multiple sclerosis on the different topographies of CISs. We prospectively evaluated 320 patients with CISs (123 with optic neuriti

To evaluate the accuracy of echo-planar T2*-weighted magnetic resonance (MR) sequences in detection of acute middle cerebral artery (MCA) or internal carotid artery (ICA) thrombotic occlusion.Forty-two consecutive patients with stroke involving the M

Objective: To determine whether edema can be assessed by MRI using T2-weighted signal intensity of hemispheric white matter in cirrhotic patients. Methods: Fast-FLAIR and magnetization transfer images were obtained before (24) and after (11) liver tr

In some rare cases, demyelinating plaques appear on contrast-enhanced T1-weighted images as pseudotumoral, cyst-like lesions (hypointense, ring enhancing). Serial proton MR spectroscopy, T2 relaxometry and magnetization transfer ratios (MTR) were per

Purpose: 3'Phosphorus magnetic resonance spectroscopy ( 31 P-MRS) provides biochemical information in a noninvasive way. The aim of this work was: (a) to characterize the 31 P spectrum of advanced head and neck tumors, and (b) to evaluate the spectra
