Venous pattern of polymicrogyria detected by susceptibility weighted imaging (SWI)
We report a case of a 9-year-old boy presenting with spastic-dystonic movement disorder of the right arm. MRI showed vast unilateral left-sided polymicrogyria (PMG) with perisylvian, temporal, frontal, and parietal location. Corresponding to the distinctly reduced gyration, the focal pattern of cortical veins in susceptibility weighted imaging (SWI) was absent due to missing sulcal depth. In co...
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 کاملAttenuation of cerebral venous contrast in susceptibility weighted imaging (SWI) in pediatric patients under general anesthesia
Introduction: Susceptibility weighted imaging (SWI) is known to depict the cerebral vascular system in great detail [1]. It seems to be a promising tool in children for early detection of cerebrovascular pathologies and better clarification of diagnosis [2]. However, young pediatric patients are oftentimes anesthetized during the MRI exam which can lead to a considerable attenuation of the cont...
متن کاملCerebral microhemorrhages detected by susceptibility-weighted imaging in amateur boxers.
BACKGROUND AND PURPOSE SWI is a new technique for evaluating diffuse axonal injury associated with punctate hemorrhages. The aim of our study was to determine the prevalence of cerebral microhemorrhages in amateur boxers compared with nonboxers by using SWI and to evaluate the sensitivity of SWI compared with T2 FSE and T2*GE sequences. MATERIALS AND METHODS We performed cranial MR imaging wi...
