- Utility of Gadolinium-Based Contrast in Initial Evaluation of Seizures in Children Presenting Emergently
The authors aimed to assess the utility of gadolinium-based contrast agents in MR imaging performed for the evaluation of acute pediatric seizure presentation. In their study population, epileptogenic findings were found in 28% of patients, but gadolinium contrast was found to be of limited additive benefit in these patients.
- Brain Maturation Patterns on Normalized FLAIR MR Imaging in Children and Adolescents
Studies to date have shown signal maturation patterns in the pediatric population using various sequences. However, there is a paucity of information about brain maturation patterns of FLAIR signal intensities across the pediatric range. Additionally, intensities vary widely across FLAIR MR imaging scanners. A FLAIR intensity standardization algorithm would be helpful to normalize intensity across large data sets, allowing comparison of FLAIR intensity in different regions and individuals.
- Epileptogenic Tubers Are Associated with Increased Kurtosis of Susceptibility Values: A Combined Quantitative Susceptibility Mapping and Stereoelectroencephalography Pilot Study
Ten patients with tubers related to tuberous sclerosis complex underwent quantitative susceptibility mapping. The QSM and R2* distributions from tubers studied with stereoelectroencephalography demonstrated that increased kurtosis of quantitative susceptibility mapping values was highly specific and associated with epileptogenicity.
