      Robust Perfusion Deficits in Cognitively Impaired Patients with Secondary-Progressive Multiple Sclerosis  
    	P.L. Francis, R. Jakubovic, P. O'Connor, L. Zhang, A. Eilaghi, L. Lee, T.J. Carroll, J. Mouannes-Srour, A. Feinstein and R.I. Aviv
  
    	American Journal of Neuroradiology January 2013, 34 (1) 62-67; DOI: https://doi.org/10.3174/ajnr.A3148 
  
    	
These authors investigated the effect of perfusion deficits on patients with MS with cognitive impairment. In 45 patients with secondary-progressive MS, cognition was assessed using standardized clinical tests and CBF and CBV perfusion maps were obtained, analyzed, and correlated with gray and white matter and lesion volumes. Perfusion in the deep gray matter nuclei and frontal cortex was significantly reduced in cognitively impaired patients with MS despite no significant differences regarding gray matter, white matter, and lesion volumes. Of the cognitive parameters investigated, information processing speed was most affected.

      Combined Diffusion and Perfusion MR Imaging as Biomarkers of Prognosis in Immunocompetent Patients with Primary Central Nervous System Lymphoma  
    	F.E. Valles, C.L. Perez-Valles, S. Regalado, R.F. Barajas, J.L. Rubenstein and S. Cha
  
    	American Journal of Neuroradiology January 2013, 34 (1) 35-40; DOI: https://doi.org/10.3174/ajnr.A3165 
  
    	
Here, the authors sought to determine if ADC values and perfusion measurements provided prognostic information in 25 treatment-naïve immunocompetent patients with brain lymphoma. The studied parameters were obtained from the enhancing tumor regions. The results of this investigation reinforce the validity of ADC values as a prognostic biomarker and provide evidence of low tumor CBV as a novel risk factor for adverse prognosis in immunocompetent patients with primary brain lymphoma.
