摘要
探索危险性的特征的目的 intrav-itreous 的加权的成像(SWI ) 在兔子的自体同源的睫毛的外国身体。12 只新西兰白兔子全部的方法 A,任何一个性,称 2.53.5 kg,并且由河南省的试验性的动物中心提供了省在这研究被采用。为每只兔子, 5 根自体同源的睫毛(在长度的 1 厘米和在直径的 0.20.3 公里) 被植入进恰好眼睛的 vitreum,当时眼睛的 vitreum 收到了的左控制假冒的操作但是任何东西都没被植入。SWI 顺序的测试手术后地被成为 2 个小时。然后,兔子被打死,兔子的玻璃的身体的标本被获得。Hematoxylin 并且曙红染色和组织学的考试被执行。在兔子的 8 眼睛的 vitreums 的自体同源的睫毛显示出的结果大小图象和危险性上的线性低信号紧张加权的图象,而是线性高度在阶段图象上表明紧张。在 12 只试验性的兔子之中,在正确 vitreum 的 5 根睫毛完全在 3 只兔子被显示出,部分在 5 只兔子(在 3 只兔子显示出的 2 根睫毛和在 2 只兔子显示出的 3 根睫毛) 出现,并且不出现在 4 只兔子。intravitreous 的外国身体的结论 SWI 在兔子的自体同源的睫毛有它的自己的特征。SWI 顺序的大小图象的联合应用程序,危险性加权的图象和阶段图象对 intravitreous 的察觉和诊断有用在兔子的自体同源的睫毛。
Objective: To explore the characteristics of susceptibility weighted imaging (SWI) of the intravitreous foreign body of autologous eyelashes in rabbits. Methods: A total of 12 New Zealand white rabbits, either sex, weighing 2.5-3.5 kg, and provided by the Experimental Animal Center of Henan Province were employed in this study. For each rabbit, 5 autologous eyelashes (1 cm in length and 0.2-0.3 mm in diameter) were implanted into the right ocular vitreum, while the left control ocular vitreum received sham operation but nothing was implanted. SWI sequential test was made 2 hours postoperatively. Then the rabbits were killed and the specimens of the vitreous bodies of the rabbits were obtained. Hematoxylin and eosin staining and histological examinations were performed. Results: The autologous eyelashes in 8 ocular vitreums of rabbits showed linear low signal intensity on the magni-tude images and susceptibility weighted images, but linear high signal intensity on the phase images. Among the 12 experimental rabbits, 5 eyelashes in the right vitreum were completely shown in 3 rabbits, partly shown in 5 rabbits (2 eyelashes shown in 3 rabbits and 3 eyelashes shown in 2 rabbits), and not shown in 4 rabbits. Conelusions: SWI of the foreign body ofintravitreous autologous eyelashes in rabbits has its own characteristics. The combined application of SWI sequential magnitude images, susceptibility weighted images and phase images is helpful to the detection and diagnosis of intravitreous autologous eyelashes in rabbits.
