Magnetic Particle Imaging: New Imaging Modality Could Advance Stroke Assessment, Other Applications
With dramatically higher sensitivity than functional magnetic resonance imaging, magnetic particle imaging could serve as a valuable tool for clinical neuroscience or diagnostic imaging modality, monitoring for hemorrhage, for example, or assessing stroke volume.

Magnetic Particle Imaging May Allow Intraoperative Breast Tumor Margin Assessment
Erica E. Mason, PhD, and Lawrence L. Wald, PhD, of the Martinos Center for Biomedical Imaging, and colleagues are exploring magnetic particle imaging as a fast way to assess margin status during breast-conserving surgery, with the aim of reducing the need for a second surgery.

MRI of Deep Brain Stimulation Devices May Be Scalable to 3T
This feasibility study is the first to show that patients with deep brain stimulation devices—even those with bilateral leads or a fully implanted system—might safely undergo MRI at 3T. It also demonstrates in one patient that better surgical management of the extracranial portions of bilateral leads mitigates risk.
