Susceptibility-weighted imaging in familial cerebral cavernous malformations.
A 59-year-old man with a family history of cerebral cavernous malformations (CCM) presented with focal seizures. T2*-weighted gradient echo (GRE) images showed multiple lesions consistent with cavernous malformations (figure 1). Susceptibility-weighted images (SWI) detected nearly triple the number of lesions than were seen with the GRE sequence (figure 2). SWI is a relatively new MRI technique...
متن کاملPneumocephalus mimicking cerebral cavernous malformations in MR susceptibility-weighted imaging.
We read with interest the article by de Souza et al 1 about the use of susceptibilityweighted imaging (SWI) for the evaluation of patients with cerebral cavernous malformations (CCMs). In this regard, we would like to report the following case: In November 2008, a 38-year-old woman presented with a history of left tinnitus and hypoacusis. The usual MR imaging sequences showed a left acoustic ne...

متن کاملSusceptibility weighted imaging (SWI).
Susceptibility differences between tissues can be utilized as a new type of contrast in MRI that is different from spin density, T1-, or T2-weighted imaging. Signals from substances with different magnetic susceptibilities compared to their neighboring tissue will become out of phase with these tissues at sufficiently long echo times (TEs). Thus, phase imaging offers a means of enhancing contra...
متن کاملCarotid - Cavernous Fistulas : Intraarterial Treatment
The intraarterial treatment of carotid-cavernous fistulas can be carried out rationally by considering a number of different factors. These include the site of the fistula , its size, its supply, its clinical presentation, associated vascular injuries, and the tolerance to carotid occlusion by a direct intraarterial balloon test. Careful attention to these features and familiarity with a variet...
