- Anatomic MR Imaging and Functional Diffusion Tensor Imaging of Peripheral Nerve Tumors and Tumorlike Conditions
In this study 29 patients underwent anatomic and functional imaging (DWI and DTI) of peripheral nerve masses in an attempt to improve their characterization. ADC values were lower in malignant tumors, the involved nerves had lower fractional anisotropy, and DTI showed differences between benign and malignant tumors. The authors concluded that tractography and fractional anisotropy provide insight into neural integrity while low diffusivity indicates malignancy.
- Impaired Default Mode Network on Resting-State fMRI in Children with Medically Refractory Epilepsy
This article explores the possibility that the default mode network as seen on resting state fMRI is abnormal in children with medically refractory epilepsy as it is in adults. Studies in 11 patients showed abnormal default mode networks with decreased connectivity but no correlations with age of seizure onset, duration of epilepsy, number of medications, seizure frequency, or IQ.
