Abstract

There are few reports of MR imaging findings following psychosurgery. Here, we report the findings of 3T MR imaging of the sequelae of stereotactic subcaudate tractotomy (SST). Rostral atrophy is noted on conventional imaging. Diffusion tensor (DT) tractography demonstrated no communicating white matter tracts between the inferior frontal lobes, which appeared normally as thick fibre bundles in age-matched controls. DT tractography provides a unique tool for the evaluation of sequelae of ablative psychosurgical procedures.

摘要

关于精神外科术后的磁共振成像(MRI)表现鲜有报道。本研究报告了 3T MRI 对立体定向尾状核下束切断术(SST)后并发症的发现。常规影像学检查发现额叶前中部萎缩。弥散张量(DT)示踪成像显示,下额叶之间没有沟通白质束,而在年龄匹配的对照组中,这些白质束表现为正常的粗纤维束。DT 示踪成像为评估消融性精神外科手术的后遗症提供了一种独特的工具。
