Conclusion DTI can well distinguish conus terminalis from filum terminale .

DTI对脊髓圆锥与终丝界限区分的初步研究

Diffusion-tensor weighted MR imaging of conus terminalis and filum terminale : a preliminary study

结果：MRI可详细了解脊髓圆锥的位置、终丝、椎管内外脂肪瘤、脊髓脊膜以及脊柱等的各种病理变化。

Result : MRI could find the level of conus tip and the pathological changes of filum , terminus , spinal lipoma , spinal cord and spinal column .

终丝脂肪瘤4例，t1加权像上见终丝结节状、线条状脂肪信号。

In 4 cases with lipoma of filum terminale , on T_1WI filum terminal had nodular or stringed lipoma signal .

方法：建立新型TCS慢性进行性终丝牵拉动物模型，进行不同时问的牵拉后解除牵拉。

Method : New type of chronic and progressing filum terminale traction model of TCS was constructed and traction was removed after different times .

目的探讨DTI脊髓成像在区分脊髓圆锥与终丝界限的可行性及临床意义。

Objective To discuss the feasibility and clinical significance of diffusion-tensor imaging ( DTI ) for distinguishing the conus terminalis from the filum terminale .

11例MRI检查显示有脊髓病变，33例MRI检查均显示有低位脊髓、圆锥位于L3～S1和终丝增粗。

MRI examination showed abnormal spinal cord in 11 cases , there were low position spinar cord , coni at lumbus 3 to sacrum 1 with thickened filum terminale in 33 cases .

方法取TCS患者内终丝近远端40例，用免疫组织化学的方法进行染色，观察巢蛋白（Nestin）表达。

Methods forty selected specimens of the distal and proximal intradural filum terminale from the people suffered from the tethered cord syndrome were used for the observation on the expression of nestin by the means of immunohistochemistry .

Thickened filum terminale . ( 5 ) the filum terminale and the neoplasms of sacral canal .

结论：颈胸髓脊髓室管膜瘤的发生率明显高于下部脊髓，圆锥和终丝。

Conclusion : Ependymomas occur seldom in the conus medullaris and filum terminale but in the upper cord .

黏液性乳头状室管膜瘤，最常出现在脊髓终丝。

This is a myxopapillary ependymoma , which is typically found arising in the filum terminale of the spinal cord .

脊髓末端位置解剖及神经干细胞在终丝中分布研究

Anatomic Study on the Vertebral Level of the Termination of the Spinal Cord and Distribution of Neural Stem Cells in the Filum Terminale

外终丝止点基本在尾1～尾2椎体间；脊髓长与身长之比逐月下降。

The lower end of external terminal filum set in position , approximating to the dorsal surface of the1st and2nd coccygeal vertebral bodies .

双管型应尽早手术治疗，如切除骨嵴，切断纤维性带状终丝，脊髓水囊肿内引流等。

The double tubular type should be treated surgically early with excision of the bony crest , excision and section of film like terminales , as well as internal drainage of hydroma of spinal cord .

用193例正常胎儿尸体观察测量了脊髓的全长、重量、体积、颈膨大、腰骶膨大及终丝等方面出生前的逐月发育值及位置的变化。

The spinal cords of 193 normal fetal cadavers were observed and measured to obtain the average value of overall length , weight , volume , cervical enlargement , lumbosacral enlargement and the terminal filum of spinal cord before birth .

中枢神经系统的一些区域已经证明可以分离培养出神经细胞，但是，位于脊髓末端的终丝被认为是不含有神经元的纤维束，没有临床意义。

Nerve cells has been confirmed can be separation culture from central nervous system , but filum terminale , which located in termination of spinal cord has been considered as fibrous bands , which contains no neurons , and systematic researches about nerve cells in filum terminale were few .

终段轴丝为9×2＋2形式。
