    • Diffusion tensor imaging in acute-to-subacute traumatic brain injury: a longitudinal analysis 

      Edlow, Brian L.; Copen, William A.; Izzy, Saef; Bakhadirov, Khamid; van der Kouwe, Andre; Glenn, Mel B.; Greenberg, Steven M.; Greer, David M.; Wu, Ona (BioMed Central, 2016)
      Background: Diffusion tensor imaging (DTI) may have prognostic utility in patients with traumatic brain injury (TBI), but the optimal timing of DTI data acquisition is unknown because of dynamic changes in white matter ...
    • In Acute Stroke, Can CT Perfusion-Derived Cerebral Blood Volume Maps Substitute for Diffusion-Weighted Imaging in Identifying the Ischemic Core? 

      Copen, William A.; Morais, Livia T.; Wu, Ona; Schwamm, Lee H.; Schaefer, Pamela W.; González, R. Gilberto; Yoo, Albert J. (Public Library of Science, 2015)
      Background and Purpose In the treatment of patients with suspected acute ischemic stroke, increasing evidence suggests the importance of measuring the volume of the irreversibly injured “ischemic core.” The gold standard ...
    • The Massachusetts General Hospital Acute Stroke Imaging Algorithm: An Experience and Evidence Based Approach 

      Gonzalez, Ramon Gilberto; Copen, William Alan; Schaefer, Pamela Whitney; Lev, Michael Howard; Pomerantz, Stuart R.; Rapalino, Otto; Chen, John Wen-Yueh; Hunter, George; Romero, Javier M.; Buchbinder, Bradley R.; Larvie, Mykol; Hirsch, Joshua A.; Gupta, Rajiv (BMJ Publishing Group, 2013)
      The Massachusetts General Hospital Neuroradiology Division employed an experience and evidence based approach to develop a neuroimaging algorithm to best select patients with severe ischemic strokes caused by anterior ...
    • Optimal Brain MRI Protocol for New Neurological Complaint 

      Mehan, William A.; González, R. Gilberto; Buchbinder, Bradley R.; Chen, John W.; Copen, William A.; Gupta, Rajiv; Hirsch, Joshua A.; Hunter, George J.; Hunter, Scott; Johnson, Jason M.; Kelly, Hillary R.; Larvie, Mykol; Lev, Michael H.; Pomerantz, Stuart R.; Rapalino, Otto; Rincon, Sandra; Romero, Javier M.; Schaefer, Pamela W.; Shah, Vinil (Public Library of Science, 2014)
      Background/Purpose Patients with neurologic complaints are imaged with MRI protocols that may include many pulse sequences. It has not been documented which sequences are essential. We assessed the diagnostic accuracy of ...
    • Time and Diffusion Lesion Size in Major Anterior Circulation Ischemic Strokes 

      Hakimelahi, R.; Vachha, Behroze Adi; Copen, William Alan; Papini, G. D. E.; He, J.; Higazi, Mahmoud Mohamad Mounir Ali; Lev, Michael Howard; Schaefer, Pamela Whitney; Yoo, Albert J.; Schwamm, Lee H.; Gonzalez, Ramon Gilberto (Ovid Technologies (Wolters Kluwer Health), 2014)
      Background: Major anterior circulation ischemic strokes caused by occlusion of the distal internal carotid artery (ICA) or proximal middle cerebral artery (MCA) or both account for about one-third of ischemic strokes with ...
