Case Reports
Reversible cerebral periventricular white matter changes with corpus callosum involvement in acute toluene-poisoning.
Substance poisoning, such as toluene intoxication, has seldom been reported in the relevant literature. The documented cerebral neuroimaging has mostly described reversible symmetrical white matter changes in both the cerebral and cerebellar hemispheres. ⋯ We discussed the underlying neuropathological pathways in this article. Hopefully, these cases will provide first-line clinicians with some valuable information with regard to toluene intoxication and clinical neuroimaging presentations.

Randomized Controlled Trial Comparative Study
Relationship between Two Types of Coil Packing Densities Relative to Aneurysm Size.
Coil packing density (PD) can be calculated via a formula (PDF ) or software (PDS ). Two types of PD can be different from each other for same aneurysm. This study aimed to evaluate the interobserver agreement and relationships between the 2 types of PD relative to aneurysm size. ⋯ Interobserver agreement for PDF and PDS was excellent. However, PDF was overestimated in smaller aneurysms and converged to PDS as aneurysm size increased.

Comparative Study
Hippocampal surface deformation accuracy in T1-weighted volumetric MRI sequences in subjects with epilepsy.
To demonstrate the accuracy across different acquisition and analysis methods, we evaluated the variability in hippocampal volumetric and surface displacement measurements resulting from two different MRI (magnetic resonance imaging) acquisition protocols. ⋯ Statistical comparison of hippocampal volumes and statistically thresholded HDM-LD surfaces in TLE patients showed no differences between the segmentations obtained in the two MRI acquisition sequences. This validates the robustness across MRI sequences of the HDM-LD technique for estimating volume and surface changes in subjects with epilepsy.

Randomized Controlled Trial
Hypophosphatemia is Associated with the Serial Administration of Triple-Dose Gadolinium to Patients for Brain MRI.
The purpose of this study is to report a metabolic abnormality associated with frequent, triple-dose Gadolinium (TdGd) use in MS patients during BECOME trial. ⋯ Serial TdGd in MS patients, unrelated to immunomodulatory treatment, was associated with increased frequency of hypophosphatemia that progressed with cumulative triple-dose and markedly decreased in second year, with less frequent triple-dose administration.
