Susceptibility 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 کاملVenous 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 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 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, ...
