Hart BL, Ketai L. Armies of Pestilence: CNS Infections as Potential Weapons of Mass Destruction. http://www.ajnr.org/content/36/6/1018.full

The imaging findings of CNS infection agents that may be used by governments and terrorist groups are presented. Viruses and anthrax are highly infectious and effective biowarfare weapons but bacteria also fulfill these requirements.

Asdaghi N, Coulter JI, Modi J, et al. Statin Therapy Does Not Affect the Radiographic and Clinical Profile of Patients with TIA and Minor Stroke. http://www.ajnr.org/content/36/6/1076.full

Imaging and clinical outcomes of high-risk patients with TIA and stroke who underwent acute statin treatment were assessed. These patients tended to be older, male, hypertensive, and have more atherosclerotic disease than those who did not receive statins. Early statin therapy was not associated with a reduction of DWI-positive lesions, infarct volume, or functional outcome at 3 months.

Shams S, Martola J, Cavallin L, et al. SWI or T2*: Which MRI Sequence to Use in the Detection of Cerebral Microbleeds? The Karolinska Imaging Dementia Study. http://www.ajnr.org/content/36/6/1089.full

The prevalence of cerebral microbleeds was evaluated in 246 patients using T2* and SWI. Microbleeds were detected in 21% by SWI vs. 17% by T2* imaging. SWI performed well with both thin and thick sections. Thus, SWI is better than T2* for this purpose and robust enough to permit comparison across studies.
