摘　　要：目的探讨体素内不一致运动(IVIM)磁共振成像在幕上脑梗死后交叉性小脑失联络(CCD)的应用价值。方法 2016年5月至2017年5月,单侧幕上脑梗死患者120例分为CCD阳性(n=60)和CCD阴性(n=60),行IVIM扫描。结果急性期和慢性期CCD阳性患者脑梗死体积(CIV)高于阴性患者(t>13.943,P<0.05);CCD阳性患者的同侧小脑表观弥散系数(ADC)与对侧存在显著性差异(t=11.413,P<0.05);对侧小脑ADC在CCD阳性与阴性患者间存在显著性差异(t=10.026,P<0.05)。结论以CIV和ADC作为评价指标,IVIM可在一定程度上反映脑梗死患者脑组织灌注程度。Objective To diagnose crossed cerebellar diaschisis（CCD） after supratentorial cerebral infarction with intravoxel incoherent motion（IVIM） magnetic resonance imaging.Methods From May, 2016 to May, 2017, 120 patients with unilateral supratentorial cerebral infarction were divided as CCD positive and CCD negative, and investigated with IVIM.Results The cerebral infarction volume（CIV） was more in CCD positive patients than in CCD negative patients in acute and chronic phase（t13.943, P〈0.05）. The apparent diffusion coefficients（ADC） was significantly different between affected and unaffected lateral cerebellar in CCD positive patients（t=11.413, P〈0.05）, and it was significantly different between CCD positive and negative patients in unaffected lateral cerebellar（t=10.026, P〈0.05）.Conclusion CIV and ADC can be the indexes of IVIM to evaluate the cerebral perfusion in patients with cerebral infarction.
