- Armies of Pestilence: CNS Infections as Potential Weapons of Mass Destruction
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.

- Screening for Self-Plagiarism in a Subspecialty-versus-General Imaging Journal Using iThenticate
The prevalence of self-plagiarism in 2 journals was investigated using commercially available plagiarism software. Self-plagiarism was low in both journals, but slightly higher in AJNR than in Radiology. Because the annual cost of screening all manuscripts is relatively low, broad screening may be justified to avoid the negative impact of self-plagiarism.
Research Perspectives
- Evidence Levels for Neuroradiology Articles: Low Agreement among Raters
Rating of articles by the original manuscript reviewers and 3 other radiologists at different time points was investigated in 100 AJNR articles. The results show that the levels-of-evidence criteria adopted for use in AJNR did not allow consistent manuscript classification between readers or even by the same reader at 2 time points.

- Statin Therapy Does Not Affect the Radiographic and Clinical Profile of Patients with TIA and Minor Stroke
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.
- SWI or T2*: Which MRI Sequence to Use in the Detection of Cerebral Microbleeds? The Karolinska Imaging Dementia Study
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.

- ASFNR Recommendations for Clinical Performance of MR Dynamic Susceptibility Contrast Perfusion Imaging of the Brain
This article discusses the utility of DSC perfusion MR imaging in the setting of tumors and ischemia and suggests guidance on its implementation, processing, interpretation, and reporting.
