Generalized tonic-clonic seizures (GTCS) comprise a common subsyndrome of idiopathic generalized epilepsy (IGE). Previous studies found that patients with GTCS had structural abnormalities in a few specific brain regions. However, the underlying clinical cause leading to these abnormalities remains unclear. The present study aimed to explore the relationship between changes in gray-matter (GM) volume and duration of epilepsy, based on GM volume differences observed between GTCS patients and healthy controls. ⋯ GM volume changes in the thalamus and frontal lobe were associated with progressive epileptic seizures. The results indicate the presence of an abnormal thalamocortical network, which may reflect an underlying pathophysiological mechanism of GTCS.

This study aimed to assess the feasibility of magnetic resonance (MR) neurography in children, and the potential roles of diffusion-weighted imaging (DWI) and fiber-tracking (FT) techniques. ⋯ MR neurography is feasible in pediatric patients. However, a considerable amount of work has yet to be done to establish its role in the clinical management of the wide range of peripheral nerve diseases.

Comparative Study
[Vertebroplasty and kyphoplasty under dual guidance (CT and fluoroscopy): radiation dose to radiologist. A comparative study].
The goals of this study is to evaluate and compare the irradiation received by the practitioner when performing percutaneous vertebroplasty or kyphoplasty guided by CT and fluoroscopy, for precise anatomical sites. ⋯ The radiation dose to radiologist is more important for kyphoplasty procedures than vertebroplasty.

To demonstrate the capability of a clinical 3T human scanner in performing quantitative MR experiments in the rat brain. ⋯ The results suggest that quantitative imaging and spectroscopy can be carried out on small animals on high-field clinical scanners.
