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.

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.
