BACKGROUND AND PURPOSE XETA, also known as Cube, is a relatively new 3D FSE sequence that can be used to perform whole-brain FLAIR T2-weighted imaging at isotropic high spatial resolution. This high-resolution volumetric imaging, coupled with both fat and fluid suppression, permits ideal evaluation of optic nerve anatomy and signal intensity; therefore, we hypothesized that XETA FLAIR would be ...

BACKGROUND AND PURPOSE High cortical signal intensity on diffusion-weighted (DW) or fluid-attenuated inversion recovery (FLAIR) images is increasingly described in sporadic Creutzfeldt-Jakob disease (sCJD). The aim of this study was to assess the extent and location of high cortical signal intensity, to investigate whether DW or FLAIR is superior in showing changes in cortical signal intensity,...

Recovery in Spontaneous Intracranial Hypotension I have read with interest the article by Tosaka et al in the June-July 2008 issue of the American Journal of Neuroradiology. The authors describe with exquisite detail the characteristics of dural and subdural fluid in spontaneous intracranial hypotension. They have recognized and collected cases describing a new sign of lineal dural hyperintensi...

Introduction Contrast-enhanced fluid-attenuated inversion recovery (FLAIR) is one of the MRI sequences that can be used for detection and evaluation of pathological changes in the brain. In this work, we have studied the effect of different echo times (TE) on the maximum relationship between signal intensity and concentration of the contrast agent using the FLAIR sequence. Materials and Methods...

Two patients presented with unusually dilated Virchow-Robin spaces appearing as cystic lesions of varying size with signal intensity identical to the cerebrospinal fluid on all magnetic resonance pulse sequences. However, fluid-attenuated inversion-recovery (FLAIR) images disclosed small, high intensity foci adjacent to these cystic lesions in one patient. These high intensity foci on FLAIR ima...

Antiangiogenic treatment using bevacizumab may cause difficulties in distinguishing between antivascular and true antitumor effects when using MRI response criteria based on changes of contrast enhancement (i.e., Macdonald criteria). Furthermore, more precise tumor response assessment criteria (i.e., RANO criteria), which incorporate nonenhancing T2/FLAIR sequences into Macdonald criteria, may ...

Studies of hadronic systems involving double strangeness (S = -2) are practically limited to searches for the Hparticle, a system of B = 2, S = -2, first proposed by Jaffe [1] which up to now was not observed. Apart from this exotic object the measurement of the interaction in hadronic systems with double strangeness is of general QCD interest and will result in a better understanding of the st...

BACKGROUND Following carotid revascularization, an abrupt increase in cerebral blood flow may disrupt the blood-brain barrier, resulting in reperfusion injury. This damage to the blood-brain barrier may be reflected by subarachnoid enhancement on FLAIR MRI after gadolinium injection. CASE PRESENTATION The authors present two cases of post-carotid stenting reperfusion injury that showed hyperi...
