Radiologic studies support this finding, in that lesions seen in NBS are not compatible with arterial territories. Furthermore, significant perilesional edema with a tendency to disappear or to leave disproportionally small residua on follow-up studies has been reported.

影像学研究也支持这一发现，因为病灶的分布不符合动脉解剖分布，而且，灶周明显的水肿随时间推移而逐渐消失或遗留下小的、不匀称的后遗症病灶。

Results showed that the topsoil structure of the CK treatment was dense with little porosity developed, and the soil microstructure was sandy granular fabric - granular fabric. In these treatments using chemical fertilizers only, the soil particles did not form soil structure with little porosity, and the soil microstructures in the N, NP or NPK treatment were observed as prophyropectic fabric-fine sand agglomerplasmic fabric, much better than the CK treatment. In those treatments receiving farm manure alone or farm manure plus chemical fertilizers, the quantity of groundmass increased obviously. The soil had a loosen structure, higher porosity, enriched animal and plant residua, iron-manganese nodules and humus, and more micro-aggregates developed. The soil microstructure of the MNPK treatment was pectized-compacted takyric fabric-intertextic fabric, the best microstructure observed among all the treatments.

结果表明：长期不施肥料的CK处理，土壤耕层结构致密，很少有孔隙发育，土壤微结构为结构较差的碎屑聚积状-沙粒聚积状；长期单施化学肥料，土壤颗粒未形成结构体，少孔隙，土壤微结构主要为斑晶胶凝状－细沙粒聚积状结构，土壤结构比CK处理优；长期施用有机肥或有机无机肥料配施的处理，土壤粗颗粒数量显著增加，结构疏松，孔隙量大，动、植物残体丰富，有铁锰结核和腐殖质的形成和微团聚体的发育，土壤微结构类型以MNPK处理最好，为胶凝紧实状－多孔状结构。
