Patient Safety
- Safety of Unilateral Endovascular Occlusion of the Cervical Segment of the Vertebral Artery without Antecedent Balloon Test Occlusion
The safety of unilateral vertebral artery occlusion without prior balloon test occlusion was retrospectively assessed in 59 patients who underwent postprocedure CT or MR imaging. No patients had clinical or imaging evidence of postprocedural infarctions. Both dominant and non-dominant vertebral arteries were safely occluded.

- Imaging Findings in MR Imaging–Guided Focused Ultrasound Treatment for Patients with Essential Tremor
This study reports the imaging findings after focused ultrasound ablation of the intermedius nuclei in patients with essential tremor. Fifteen patients received follow-up MRI studies on 4 occasions after treatment. Maximal lesion size and perilesional edema predicted a good outcome and all lesions showed consistent and typical findings in the days, weeks, and months after treatment.

- Bioactive versus Bare Platinum Coils in the Treatment of Intracranial Aneurysms: The MAPS (Matrix and Platinum Science) Trial
This prospective, randomized, multicenter study compares the efficacy of the Matrix versus bare metal coils. A group of 626 patients were divided between the 2 coil types and aneurysm recurrence and hemorrhage were assessed 1 year after procedures. Recurrences were associated with initial incomplete obliterations and the bare metal coils were not inferior to Matrix coils. Thus, due to cost differences, utilization of Matrix coils may not be justified.
