PRS:技术更新!三维成像设计条形颅骨切除术虚拟头盔

2021-03-16 MedSci原创 MedSci原创

传统头盔方案和虚拟头盔方案均改善了平均头颅指数,但虚拟头盔组的头颅指数变化更一致、更大。虚拟头盔设计方案产生了与年龄匹配的对照组相似的三维结果。与虚拟头盔组和对照组相比,传统头盔设计产生了更窄的双顶尺

微创条形颅骨切除术是治疗矢状缝颅缝畸形的安全有效的治疗方法。头盔疗法是矢状条形颅骨切除术后最常见的辅助手段,用于促进颅顶的被动重塑。颅骨的快速生长、颅骨的延展性、楔形截骨术的增加和头皮的顺应性使颅顶发生了快速的三维变化。在术后早期,头盔允许婴儿仰卧,头部的重量放在枕骨上,从而允许顶骨的被动侧向运动,从而促进颅顶的快速重塑。头盔还限制了不必要的过度垂直膨胀。矢状面融合的限制性和补偿性生长模式存在显著差异。矢状条形颅骨切除术后佩戴的头盔必须根据手术程序和患者的解剖结构定制,以确保不会因顶骨与头盔的任何部分意外接触而抑制被动扩张,以达到最佳效果。

这项研究比较了一种新的虚拟头盔设计和一种传统头盔设计所获得的三维头型结果,并将每组受试者与年龄匹配的对照组受试者进行了比较。

该研究共纳入24例患者。11名患者组成了传统的头盔组,基于激光扫描设计头盔。13名患者组成虚拟头盔组,基于低辐射方案计算机断层扫描和三维照片的三维体绘制叠加设计头盔。从三维照片上记录头颅指数和垂直高度。生成三维全头复合图像,以比较全球头型结果与年龄匹配的对照组的结果。

虚拟头盔组平均头颅指数(83.70±2.33)分与对照组(83.53±2.40)分比较,差异无统计学意义(P>0.05)。

传统头盔组平均头指数(81.07±3.37)与对照组比较差异有统计学意义(P<0.05),平均垂直高度差异有统计学意义(P<0.05)。

三维分析显示,与对照组相比,虚拟头盔组的双顶和垂直维度正常。与对照组相比,传统头盔组的双顶径较窄,垂直径较大。

传统头盔方案和虚拟头盔方案均改善了平均头颅指数,但虚拟头盔组的头颅指数变化更一致、更大。虚拟头盔设计方案产生了与年龄匹配的对照组相似的三维结果。与虚拟头盔组和对照组相比,传统头盔设计产生了更窄的双顶尺寸和更大的颅顶垂直尺寸。这支持使用三维成像来评估矢状位颅缝融合症的治疗结果。

三维成像技术在心脏再同步化治疗中的应用

摘要:心脏再同步化治疗能改善心力衰竭患者的临床症状及预后。然而,研究表明,约40%的病人对这种治疗的反应较差。确定心脏再同步化治疗效果的三个主要因素是:左心室收缩不同步,左心室电极的位置, 心肌疤痕组织的部位范围。二维超声心动图是第一个用来评估心脏再同步化治疗病人的成像技术。然而,三维成像技术可以更全面的评价这些患者心脏再同步化治疗前后病理生理的改变及其效果。 关键词:心力衰竭;再同步化治疗;三维

Development:三维成像告诉你,胚胎植入之初,小鼠子宫内发生了哪些变化?

导读 虽然我们对胚胎发育了解颇多,但是胚胎发育初期子宫内部环境的变化仍然有很多未知。近期,加州大学旧金山分校的研究团队研发了一套三维成像体系,通过将成像技术与3D分析软件结合,首次实现了对小鼠胚胎植入初期子宫的可视化观察,展现了子宫内膜结构在受孕初期的变化。12月13日,Development期刊发表一篇文章揭示了小鼠怀孕初期子宫环境发生的变化。来自于加州大学旧金山分校的研究团队首次实现了受孕初期

阜外医院研究称:心脏超声三维成像评估心功能,效果堪比核磁共振

阜外医院吴伟春等研究提示,3D 心脏解剖模型成像法能够准确测量左室舒张末容量(LVEDV)及左心室射血分数(LVEF),并且重复性好,客观性强,是一种值得推荐的测量心功能的新方法。 3D 心脏解剖模型成像应用程序是一个三维超声测量心脏功能的新方法,这种方法采用先验的知识(正常和异常心脏模型),使三维的方法能够迅速地分析出不同疾病的心脏形态和容量,得到更加准确的心脏容积和收缩功能。

Radiother Oncol:PET能帮助确定口咽部肿瘤患者放疗靶区和预测患者预后

肿瘤亚型的空间结构关系到放疗靶区的确定和对患者结局的预测。Matthew J等旨在调查在口咽部肿瘤的患者中,通过三维成像PET影像数据确定肿瘤亚型和肿瘤代谢、增生和乏氧状态的关系。来自美国威斯康辛大学的研究者就上述问题进行了研究并将结果发表在Radiother Oncol 10月的期刊上。 口咽部肿瘤患者接受18F-氟去氧葡萄糖(FDG) PET/CT、18-氟三氯甲烷(FLT) PET/CT和

J Neurosurg Anesthesiol:岛叶切除对自主神经活动的影响

岛叶(Insula)为大脑皮质的一部分,是向内凹陷的皮层区域,被包埋在外侧裂之内,无法直接从完整的脑的外部观察到;其与额叶,颞叶和顶叶的皮层相连通。此外,岛叶亦是中枢自主网络的基础结构,在自主神经对环境应激因素的反应中发挥着重要的作用。此前,研究人员主要就脑血管事件,对岛叶在人自主神经调节中的作用进行了探讨,但是由于缺乏脑血管事件前后时间相关进程的对照,使得对于这些发现的解释变得更加复杂。然而,通
