Diffusion Weighted MRI Patterns Caused by Acute Border Zone Infarction

چکیده
nisms contributing to acute border zone infarctions. These include hemodynamic factors, embolic factors or both (1-6), and were determined by a transcranial Doppler (TCD) study and autopsies (7, 8). Before the era of magnetic resonance imaging (MRI), a computed tomography (CT) was the only method for diagnosing infarctions; however, due to limited resolution, subtle lesions caused by disseminated cortical infarctions could not be determined. The advent of diffusion-weighted imaging (DWI) led to the ability of identifying subtle lesions accompanied with acute border zone infarctions; namely disseminated cortical infarctions consisting of scattered small cortical high signal intensities.

Lesion patterns and mechanism of ischemia in internal carotid artery disease: a diffusion-weighted imaging study.
CONTEXT Although embolism and low-flow phenomenon are the 2 main mechanisms of stroke in internal carotid artery (ICA) occlusive disease, the mechanism of border-zone infarction remains controversial. Diffusion-weighted imaging (DWI) can more easily detect small or multiple ischemic lesions than conventional imaging. OBJECTIVES To investigate the ischemic lesion patterns on DWI and to discuss...
متن کاملSpecific DWI lesion patterns predict prognosis after acute ischaemic stroke within the MCA territory.
BACKGROUND Apart from diffusion-weighted imaging (DWI) lesion volume and diffusion-perfusion mismatching, there is limited information about neuroradiological predictors of early prognosis after an ischaemic stroke. This study sought to identify specific DWI lesion patterns that would help prediction of early prognosis of three different endpoints: unstable hospital course, recurrence of stroke...
متن کاملLesion patterns and stroke mechanism in atherosclerotic middle cerebral artery disease: early diffusion-weighted imaging study.
BACKGROUND AND PURPOSE Patterns and mechanisms of stroke in patients with atherosclerotic middle cerebral artery (MCA) disease remain unclear. We sought to identify lesion patterns and stroke mechanisms associated with MCA disease using early diffusion-weighted imaging (DWI). METHODS We reviewed 185 acute ischemic stroke patients who had (1) symptomatic lesions located in the unilateral MCA t...
متن کاملInternal and cortical border-zone infarction: clinical and diffusion-weighted imaging features.
BACKGROUND AND PURPOSE The pathogenesis of internal border-zone (IBZ) and cortical border-zone (CBZ) infarcts is unclear. Both types of infarct have been combined into a single group in most previous reports, which has produced conflicting results. We hypothesized that different pathogenic mechanisms underlie IBZ and CBZ infarcts. METHODS We reviewed 946 consecutive patients with ischemic str...
متن کاملTemporal changes of microvascular obstruction and infarct border zone after acute myocardial infarction assessed by contrast enhanced magnetic resonance imaging
Background Besides total scar size, scar characterization parameters are emerging as additional prognostic factors after acute myocardial infarction. Of these, microvascular obstruction (MVO) and infarct border zone are the most promising ones. Nevertheless, a MRI scan performed few days after infarction assesses a rapidly changing myocardium. In particular the infarct border zone that is belie...
