Single photon emission computed tomography assessments were conducted in normal controls (n = 25), patients with unilateral cerebellar infarctions (n = 4), patients with olivopontocerebellar atrophy (OPCA; n = 15) and patients with Friedreich's ataxia (FA; n = 6). In subjects with unilateral cerebellar infarctions, crossed cerebellar-cortical diaschisis was observed: reduced cerebellar hexamethylpropyleneamine oxime (HMPAO) uptake was invariably accompanied by a diminution of HMPAO in the contralateral basal ganglia and frontoparietal cortex. OPCA and FA patients had various degrees of decreased HMPAO uptake in both the cerebellum and cerebral hemispheres.
对正常对照组（n = 25）、单侧小脑梗死患者（n = 4）、橄榄体脑桥小脑萎缩（OPCA；n = 15）患者和弗里德赖希共济失调（FA；n = 6）患者进行了单光子发射计算机断层扫描评估。在单侧小脑梗死患者中，观察到交叉性小脑 - 皮质失联络：小脑六甲基丙烯胺肟（HMPAO）摄取减少总是伴随着对侧基底神经节和额顶叶皮质中HMPAO的减少。OPCA和FA患者的小脑和大脑半球均有不同程度的HMPAO摄取减少。
