Objective: to have some understanding of MRI diagnostic typing of brain gray matter heterotopia.
目的：提出脑灰质异位症的M R I诊断分型，提高对本病的认识。
Objective To evaluate the role of MRI in diagnosis and differential diagnosis of gray matter heterotopia(GMH).
目的探讨脑灰质异位症（GMH）的MR I诊断及鉴别诊断。
There are three clinically useful classifications of gray matter heterotopia: subependymal, band, and subcortical heterotopia.
临床上有三种分类：室管膜下、带状、皮层下灰质异位。
Results: Brain gray matter heterotopia were classified into four types according to their locations and shapes: subependymal type, non-subependymal type, nodular type and diffuse-type.
结果：灰质异位症依据形态与位置，主张将其分为四型：室管膜下型、非室管膜下型、结节型、弥漫型。
Band heterotopia is diagnosed by visualization on MRI of a smooth layer of gray matter separated from the cortex and ventricles by white matter.
带状异位在MRI上表现为一个平滑的灰质带位于脑室和皮质之间，中间夹以脑白质。
Band heterotopia is diagnosed by visualization on MRI of a smooth layer of gray matter separated from the cortex and ventricles by white matter.
带状异位在MRI上表现为一个平滑的灰质带位于脑室和皮质之间，中间夹以脑白质。
