A 26-year-old patient underwent endoscopic third ventriculostomy for the treatment of obstructive hydrocephalus. 3D volume data sets were obtained at 3 T before surgery and three times after surgery. Off-line analysis of individual imaging data (initial linear registration, intensity adjustment, and final nonlinear registration of pre- to postoperative MR images) yielded 3D displacement fields representing the postoperative structural brain change. In principle, such an analysis technique can be used in any clinical follow-up for which careful observation of tissue readjustment is of particular importance.
一名26岁的患者接受了内镜下第三脑室造瘘术以治疗梗阻性脑积水。在手术前及术后三次于3T获取三维容积数据集。对个体影像数据进行离线分析(术前至术后磁共振图像的初始线性配准、强度调整及最终非线性配准)得出代表术后脑结构变化的三维位移场。原则上,这种分析技术可用于任何对组织重新调整的仔细观察尤为重要的临床随访。
