Imaging cerebral malaria with a susceptibility-weighted MR sequence.
MR Sequence Cerebral malaria is a severe complication seen in approximately 2% of patients with acute Plasmodium falciparum infection. Characteristic diffuse petechial hemorrhages that were previously only seen by gross pathologic or microscopic examination, and virtually undetectable by conventional imaging modalities, were well demonstrated in a patient with cerebral malaria, with use of susc...
متن کاملDetecting Cerebral Microbleeds on Susceptibility-Weighted MR Imaging: Comparison with the Conventional MR Imaging Sequences
spontaneous, homogeneous, round foci of low signal intensity on the gradient-recalled echo (GRE) imaging sequence (1, 2). The prevalence of microbleeds in healthy adults is about 5% (2). Microbleeds may be a marker for cerebral microangiopathy and small vessel disease, and they may be a prognostic indicator for potential future bleeding, and especially for patients with ischemic or hemorrhagic ...
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 کاملImaging cerebral amyloid angiopathy with susceptibility-weighted imaging.
Gradient-echo (GE) imaging is recognized as a means to detect hemorrhagic changes in cerebral amyloid angiopathy (CAA). However, almost 25% of patients with CAA do not show microhemorrhages on T2* GE imaging. We applied a new imaging method, susceptibility weighted imaging (SWI), to evaluate the presence of microhemorrhages. In a suspected case of CAA, where cognitive effects are also present, ...
متن کاملMR imaging detection of cerebral microbleeds: effect of susceptibility-weighted imaging, section thickness, and field strength.
BACKGROUND AND PURPOSE The emergence of cerebral microbleeds (CMB) as common MR imaging findings raises the question of how MR imaging parameters influence CMB detection. To evaluate the effects of modified gradient recalled-echo (GRE) MR imaging methods, we performed an analysis of sequence, section thickness, and field strength on CMB imaging properties and detection in subjects with cerebral...
