资源简介:
Multimodal funtional MRI (fMRI) may require the implantation and fixation of e.g. optical fibers into the skull and brain of rodents. Adhesives were found to induce magnetic susceptibilities, causing image artifacts for MRI at high field strengths (>7 T). Samples consisted of a tube filled with 1% agarose, with 1-3 patches of adhesive fixed to the top of the tube. The labels of the adhesives signify their chemical class (silicone-based, cement-based, nail acrylics, unfilled dental resins, filled dental resins, household acrylics, glass ionomer, dental plaster). Trade names of the adhesives can be retreived from the linked publication. This dataset contains: 1 MRI data: All images are single-shot, multislice 2D gradient echo EPI, acquired on preclinical MRi systems and supplied in DICOM format. 1.1 Adhesives applied in constrianed geometry (identical shape and volume) 1.1.1 samples scanned at 9.4 T 1.1.2 samples scanned at 7.0 T 1.2 Adhesives applied in unconstrained geometry with three different volumes per adhesive (scanned at 9.4 T) 1.3 Adhesives applied with constant weight (0.05 g) but either as flat or spherical patch 1.4 In vivo MRI of mice with implanted optical fiber, fixed with adhesive unre.1 2 The results of pull-out force tests to determine the adhesive force of adhesives on an ex vivo mouse skull.

多模态功能磁共振成像(functional Magnetic Resonance Imaging,fMRI)在相关研究中通常需要将光纤等器件植入并固定于啮齿类动物的颅骨与脑组织内。研究发现,粘合剂会诱发磁化率变化,进而在高场强(>7特斯拉)的磁共振扫描中产生图像伪影。本次实验所用样品为装载1%琼脂糖(agarose)的试管,试管顶部固定有1至3块粘合剂贴片。粘合剂的标签标注了其所属的化学类别:有机硅基类、水泥基类、美甲用丙烯酸树脂、无填充牙科树脂、填充牙科树脂、家用丙烯酸树脂、玻璃离子水门汀、牙科石膏。粘合剂的商品名称可从关联出版物中获取。 本数据集包含以下内容: 1 磁共振成像数据:所有图像均为单次激发多层面二维梯度回波平面成像(Echo Planar Imaging,EPI),采集自临床前磁共振成像系统,以DICOM格式提供。 1.1 受约束几何构型(形状与体积均一致)下的粘合剂贴片样本 1.1.1 于9.4特斯拉场强下扫描的样本 1.1.2 于7.0特斯拉场强下扫描的样本 1.2 无约束几何构型下的粘合剂贴片样本,每种粘合剂对应三种不同体积(于9.4特斯拉场强下扫描) 1.3 固定重量(0.05克)但形态分别为扁平状与球状的粘合剂贴片样本 1.4 植入光纤并通过unre.1粘合剂固定的小鼠体内磁共振成像扫描数据 2 拉拔力测试结果:用于测定粘合剂在离体小鼠颅骨上的粘附力。
