DOI: 10.1007/s00234-019-02338-2
Abstract: Dear Editor, Perivascular spaces—or Virchow-Robin spaces—are piallined interstitial fluid-filled spaces which surround the vessels as they course from the subarachnoid space through the brain parenchyma [1, 2]. Perivascular spaces are commonly encountered on MR imaging,… read more here.
