Iopamidol,a new non-ionic hydrosoluble contrast medium for neuroradiology

Summary The side effects associated with the use of Iopamidol for myelography were determined in 100 patients and compared with metrizamide in a double-blind study.     

中央型腰椎间盘突出症(附52例报告)

本文报告52例中央型腰椎间盘突出症。本组有3种表现类型:一般间盘突出型、椎管狭窄型和马尾神经综合征型。并重点分析了各型的临床表现、手术治疗和治疗效果。讨论了中央型腰椎间盘突出症与病理改变之间的关系。     

MR脊髓成像：单次激发快速自旋回波序列技术的应用

目的：评价单次激发快速自旋回波序列（Single-shot TSE）在脊髓成像中的价值。材料与方法：400例腰背部疼痛患者行MR检查（Siemens1.5T Magnetom Symphorny）。所有扫描序列均配以脊柱相控阵线圈。扫描序列如下：（1）TSET2W;（2）TSET1W;（3）Single-shotTSE。结果：Single-shotTSE显示管优秀,病变轮廓勾画清晰。诊断椎管梗阻及压迫准确性为100％。对于常规MR序列显示不佳的囊肿有很好的显示,信噪比及对比度噪声比均大大提高。结论：单 激发快速自旋回波序列的优点：（1）成像时间短;（2）背景抑制好;（3）对病变显示的敏感性及准确性高。     

Spina bifida occulta: Radiographic and operative correlation

The clinical and myelographie evaluation in 24 children with spina bifida occulta has been correlated with the operative findings. Myelograms were done using Myodil in 11 patients and Metrizamide in 13 patients. The diagnostic quality of myelograms done with Metrizamide was comparatively better. Myodil myelography failed to demonstrate diastematomyelia in one case and a durai sac in 3 cases of lipomeningomyelocele, whereas, Metrizamide failed to demonstrate a sac in one case of lipomeningomyelocele only. Worsening of the neurological status was observed in only 3 cases in whom myelography was done with Myodil. The radiographie and operative correlation has been discussed.     

颈椎病手术效果不佳原因分析(附46例报告)

从1978年5月至1992年5月手术治疗颈椎病400例,其中46例（11.5％）手术效果不满意。46例中有22例（47.8％）经再次手术治疗。作者通过手术前后脊髓造影或CT检查分析了各种因素,发现与手术有关（31例67％）为主要因素。提出年龄大、病史长、广泛椎管狭窄、多节段病变常导致脊髓横断面积减少,如有上述两种以上的综合因素,疗效会更差。     

Lumbar myelography with iopamidol: A methodological approach to the investigation of side effects

Summary Pathophysiology of adverse reactions occurring during myelography with non-ionic contrast agents, such as iopamidol, seem related to their direct action on the nervous system. The authors try a multivariate approach, involving neurophysiological, neuropsychological and neurochemical parameters on a pilot group of twelve subjects. Any possible change in the above examinations is throughly analyzed and correlated to the postulated neurotoxic properties of contrast media.     

Primitive neuroectodermal tumor in a 57-year-old man

Primitive neuroectodermal tumors are rare cerebral neoplasms previously described only in children and young adults. This report describes such a tumor arising in the left frontal lobe of a 57-year-old man. After surgical resection and radiation therapy to the primary site, the patient developed extensive central nervous system metastases that led to his death. The histopathologic, radiographic, and clinical features of this case suggest that future therapeutic protocols for primitive neuroectodermal tumor should be similar to those for childhood medulloblastoma or neuroblastoma.     

Aseptic meningoencephalitis following iohexol myelography

We report a case of aseptic meningoencephalitis complicating iohexol myelography and compare this case with previous reports of neurotoxicity from intrathecal contrast media.     

116例腰椎管狭窄症临床分析

本文报告手术治疗的116例腰椎管狭窄症。以脊髓造影改变为主要诊断依据,将其分为5种类型、手术根据狭窄类型、部位和程度采用全椎板、半椎板切除或椎板开窗。强调侧隐窝充分减压。79例术后随访1～9年,痊愈达62％,良好为20.3％。着重讨论了本症的诊断及手术要点。     

Atlantoaxial instability in marfans syndrome. Diagnosis and treatment

Summary A case of Marfans syndrome is described in which progressive neurological signs and symptoms were produced by flexion of the head. Radiological examinations revealed hypermotility between the atlas and axis, as well as compression of the medulla oblongata by the odontoid process on flexion, since low positioned cerebellar tonsils prevented dorsal shift of the oblongata. The signs and symptoms disappeared after occipitocervical internal transfixation.
