A group of 22 patients with type 2 diabetes underwent MR spectroscopy of the deep gray matter nuclei and their metabolite ratios of NAA/Cr and Cho/Cr were assessed and correlated with laboratory findings. Metabolite ratios were different in the left and right lenticular nuclei and in the thalami, suggesting that diabetes affects these differently with the former being more vulnerable than the latter. The metabolic abnormalities preceded anatomic lesions.

This article explores the usage of CTA and DSA in nearly 5000 patients with ruptured aneurysms. During a 5-year period, use of CTA more than doubled to 44% of all patients while the use of DSA remained stable (94–96%). The same trend was observed for patients undergoing coiling or clipping and following treatment the use of imaging increased from 41% to 48%, especially in clipped patients. The use of DSA as a second test is potentially redundant.
