3D pseudocontinuous arterial spin-labeling perfusion imaging detected crossed cerebellar diaschisis in acute, subacute and chronic intracerebral hemorrhage

Objective We aimed to evaluate the value of 3D pseudocontinuous arterial spin-labeling (pCASL) perfusion imaging detected crossed cerebellar diaschisis (CCD) at different stages of intracerebral hemorrhage (ICH). Materials and methods We assessed bilateral cerebral blood flow (CBF) values of different brain regions and the relationships between the CCD and clinical status of 16 ICH patients. Results The ICH patients had significantly lower CBF values in the contralateral cerebellum in acute, subacute and chronic stages. The subacute CCD had a significant correlation with clinical status. Conclusions 3D pCASL may be an ideal tool to study the phenomenon and clinical consequences of ICH with CCD.
