Abstract
Objective:By analyzing signs of 27 cases of MRI and MRA images of moyamoya disease (MMD),to further improve the diagnosis level of moyamoya disease.Methods:Via retrospective analysis of 27 patients with cerebral MRI and MRA check and MMD patients' image data which confirmed to MMD diagnosis standard enacted in 1997 by the Japanese Moyamoya Disease Research Council,summing up the MRI and MRA characteristic signs.Results:MRI could clearly show substantive damage of MMD patients with cerebral infarction,cerebral hemorrhage,cerebral softening,or brain atrophy,and low signal vascular network of anomaly expansion and circuitous of basement department of brain were visible:5 cases in T1WI and FLAIR saw leptomeninges signs; 3 D-TOF MRA directly showed the ICA end and (or) ACA,MCA near-end occlusion or stenosis,smoke shape arteriolar and cerebral collateral circulation; CE-MRA displayed collateral vessels more clearly; MRI signs of brain damage and MRA signs of vascular stenosis or occlusion condition were not completely consistent,which had close relation to cerebral collateral circulation angiogenesis.Conclusion:MRA sign of moyamoya disease has characteristics,so do MRI signs of smoke shape empty vessels shadow and leptomeninges but not as intuitive as MRA.MRI signs of brain damage have close relationship with MRA signs of collateral circulation,MRI and MRA could make clear MMD diagnosis.关键词
