    Department of Radiology, Massachusetts General Hospital, 55 Fruit Street, Boston, MA 02114, USA
    Neuroimaging Clin N Am 21:215-38, ix. 2011
    ..A qualitative estimate of the presence and degree of ischemia is typically required for guiding clinical management. Radiation dose issues with CTP imaging, a topic of much current concern, are also addressed in this review...
