Abstract:
Objective To study the diagnostic value of CDE in moyamoya disease.Methods The intra-and-extracranial arteries in 17 patients with moyamoya disease and 25 healthy volunteers were studies by CDE.The resistance index(RI),pulsatility index(PI),time-averaged flow velocity(Vm)were examined in arteries,including MCA、MCA、ACA、PCA、CCA、ICA、ECA and TSA.Results ①The diagnosis rate of the occlusion or stenosis in intracranial arteries was 87.25%.②The hemodynamic characteristics of CCA and ICA were high flow velocky and low resistance opposite to that of TSA.③The moyamoya vessels were seaned in 10 of all 17 patients with moyamoya disease by CDE.The diagnosis rate of moyamoya disease was 58.82%.Conclusions CDE technique could image the moyamoya vessels as scattered color dots. So CDE had a higher clinic value in diagnosis of moyamoya disease.
