- Dual-Layer Detector Head CT to Maintain Image Quality While Reducing the Radiation Dose in Pediatric Patients
Radiation exposure from CT scanning is of increasing concern as CT use in children has risen dramatically. This retrospective study of pediatric CT heads aimed to compare 60-keV with conventional images obtained with different acquisition protocols to evaluate whether a reduced radiation dose can be achieved in 60-keV without compromising image quality. On the basis of image analysis and observer agreement assessment, the authors found a dose reduction of 28% while maintaining superior image quality with a scan protocol of 180 mAs compared with 250 mAs on 60-keV virtual monoenergetic images from spectral detector CT in the pediatric head.
- 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.
