We report 2 cases of subcortical band heterotopia (SBH) with emphasis on double inversion recovery (DIR) magnetic resonance imaging (MRI). The heterotopic gray matter demonstrated homogeneous high signal intensity and the delineation between the SBH and white matter was distinctly depicted on DIR MRI. Double inversion recovery is a useful adjunct to conventional MRI for the diagnosis of SBH.
我们报告2例皮质下带状异位（SBH）病例，重点介绍双反转恢复（DIR）磁共振成像（MRI）。异位灰质表现为均匀高信号强度，SBH与白质之间的界限在DIR MRI上清晰显示。双反转恢复是传统MRI诊断SBH的有用辅助手段。
