Klitsie, C.N. De Cecco, C.S. Zhou, S. Luo, G.M. Lu and L.J. ZhangAmerican Journal of Neuroradiology October 2016, 37 (10) 1774-1780; DOI: https://doi.org/10.3174/ajnr.A4803
A cohort of 204 patients were randomly divided into 2 groups. Patients in group A (n = 102) underwent 80-kVp CTA with 30 mL of contrast agent, while patients in group B (n = 102) underwent conventional CTA (120 kVp, 60 mL of contrast agent). With DSA as a reference standard, diagnostic accuracy on a per-aneurysm basis was 89.9% for group A and 93.9% for group B. The authors conclude that in detecting intracranial aneurysms, 80-kVp/30-mL contrast CTA provides the same diagnostic accuracy as conventional CTA with substantial radiation dose and contrast agent reduction.

- EDITOR'S CHOICEAdult BrainOpen AccessMagnetic Susceptibility from Quantitative Susceptibility Mapping Can Differentiate New Enhancing from Nonenhancing Multiple Sclerosis Lesions without Gadolinium InjectionY. Zhang, S.A. Gauthier, A. Gupta, L. Tu, J. Comunale, G.C.-Y. Chiang, W. Chen, C.A. Salustri, W. Zhu and Y. WangAmerican Journal of Neuroradiology October 2016, 37 (10) 1794-1799; DOI: https://doi.org/10.3174/ajnr.A4856
In 54 patients, new T2-weighted lesions were evaluated for enhancement on conventional T1-weighted imaging with gadolinium, and their susceptibility values were measured on quantitative susceptibility mapping. Eighty-six of 133 new lesions that were gadolinium-enhancing had relative susceptibility values significantly lower than those of nonenhancing lesions. Using susceptibility values to discriminate enhancing from nonenhancing lesions showed a sensitivity of 88.4% and specificity of 91.5%, with a cutoff value of 11.2 parts per billion for QSM.
