To assess the MR characteristics and gain the experience in making the diagnosis and differentiation of spinal cord tumors, 30 cases with intramedullary tumors and 20 cases with tumor-like lesions were comparatively evaluated. It was concluded that MR characteristic findings of intramedullary tumors are cord widening, marked Gd enhancement and associated cysts. Compared with neoplasms, the MR feature of nontumor lesions are without or with slight cord widening, mild or moderate, mostly eccentric enhancement with peripheral (ringlike), punctate, speckled or patchy patterns. Gd plays a very important role in making the diagnosis and differentiation of the spinal cord tumors.

本文通过对30例髓内肿瘤和20例非肿瘤病变MR表现的回顾性对比分析,总结了髓内肿瘤MR诊断和鉴别诊断经验。指出髓内肿瘤的MR主要征象为脊髓局部增宽、膨大,病灶Gd-DTPA明显强化,以及伴有囊变。而非肿瘤病变脊髓轮廓改变较轻,Gd-DTPA为轻至中度强化。增强特点为偏心性、点片状或环状,较具特异性。

The manifestations of Gd-DTPA enhanced MRI in 37 cases with spinal tumors proved surgically and pathologically,were reported.This study included the following three types of tumors:(1)intramedullary tumors(2 astrocytomas,4 Ependymomas and 2 hemangioblastomas);(2)extramedullary intradural tumors (12 neurofibromas,2 meningiomas);and (3)extradural tumors (2 meningiomas,2 neurofibroma and 1 metastasis).our results showed that this contrast medium had good enhancement effects,including 26 cases with homogeneous enhancement and 11 cases with inhomogeneous enhancement.Gd-DTPA enhanced MRI is helpful in determining location,shape,size,margin and structure of Spinal tumors,especially in differentiating solid lesion from necrotic and cystic one of intramedullary tumors,and Syringomyelia.Therefore,authors suggest that Gd-DTPA enhanced MRI Should be the routine modality of choice in Spinal tumors.

本文报道了椎管肿瘤37例的MR增强结果,全部病例均经手术和病理证实。髓内肿瘤18例,其中,星形细胞瘤12例,室管膜瘤4例,血管母细胞瘤2例。髓外硬膜下肿瘤14例,其中,神经纤维瘤12例,脊膜瘤2例。硬膜外肿瘤5例,其中,脊膜瘤和哑铃状神经纤维瘤各2例,转移瘤1例。使用磁显葡胺MR增强后,所有肿瘤均有明显增强,均匀者26例,不均匀者11例。并对肿瘤形态、位置、大小、轮廓和结构等显示更精确,特别是对髓内肿瘤的实体与坏死、囊变、继发空洞等的鉴别,更有帮助。故采用磁显葡胺MR增强有助提高诊断水平,应列为常规扫描方法之一。

Objective: To evaluate the value of MRM in diagnosing the diseases of spinal canal and to study the practical technique.Materials and Methods:The MRM and conventional MRI findings in 71 patients with spinal canal diseases were analyzed. The cases were consisted of the following diseases: intramedullary tumors 8, intradural extramedullary tumors 14, extradural tumors 9, vertebral tuberculosis 3, spinal injuries 7, spinal dysraphism 6, intervertebral disc hernia and bony stenosis of the spinal...

Objective: To evaluate the value of MRM in diagnosing the diseases of spinal canal and to study the practical technique.Materials and Methods:The MRM and conventional MRI findings in 71 patients with spinal canal diseases were analyzed. The cases were consisted of the following diseases: intramedullary tumors 8, intradural extramedullary tumors 14, extradural tumors 9, vertebral tuberculosis 3, spinal injuries 7, spinal dysraphism 6, intervertebral disc hernia and bony stenosis of the spinal canal 24 cases.Results:MRM could distinguish structures with minor differences in signal, which could be hardly distinguished by the conventional MRI. MRM 3D MIP reconstruction was superior to the conventional MRI in demonstrating the anatomical relationship between the lesions and the spinal canal. For demonstrating the solid structures of tumors and extradural lesions, MRM was inferior to the conventional MRI.Conclusion: Compared with other myelography, MRM has the advantages of nonivasive, easy to study and without any complications. The accuracy of MRM in diagnosing the spinal canal diseases can be further increased if combined with conventional scan sequence of MRI.

目的:探讨MRM诊断椎管病变的价值及MRM技术方法。材料与方法:对71例椎管病变的常规MRI检查及MRM表现进行了分析,其中髓内肿瘤8例,髓外硬膜内肿瘤14例,硬膜外肿瘤9例,结核3例,脊椎外伤7例,脊柱闭合不全6例,椎间盘突出及骨性椎管狭窄24例。结果:MRM可显示常规扫描不能显示的信号差别小的结构,MRM3DMIP重建显示椎管整体结构与病变的关系优于常规扫描,但对肿瘤的实性结构、硬膜外病变的显示则不如常规扫描序列。结论:MRM与其他脊髓造影方法相比具有无损伤、无并发症、操作灵活方便等特点,与常规扫描序列相结合可显著地提高椎管病变的诊断价值
