自非离子型水溶性碘造影剂问世以来,脊髓造影技术及安全性有了很大提高。由于非离子型造影剂具有低渗透性、低毒性、低粘度和吸收快等优点,我院放射科自90年以来已停用油质造影剂而改用非离子型造影剂欧乃派克(Omnipaque)作为脊髓造影CT扫描(CTM)用造影剂,取得满意效果。现将资料较完整的100例临床应用情况报告如下。 材料和方法 本组100例均为非对照性临床应用验证。男64例,女36例;年龄8～69岁,平均45.2岁。患者诊断为椎管内占位性病变62例,椎管狭窄11例,椎间盘脱出8例,蛛网膜炎4例,其他待查15例。 CT机为西门子Somatom CR3,造影剂浓度为300mg/ml,剂量为6ml/次。 患者侧卧,头高10°～15°,用9号腰穿针于腰3—4或腰4—5
Since the advent of non-ionic water-soluble iodine contrast agent, myelography and safety has been greatly improved. Due to its low permeability, low toxicity, low viscosity and fast absorption, non-ionic contrast medium has been discontinued for 90 years due to its non-ionic contrast agent Omnipaque ) As contrast agent for myelography CT scan (CTM), to obtain satisfactory results. Now more complete information on the clinical application of 100 cases are as follows. Materials and methods The group of 100 cases are non-controlled clinical application verification. 64 males and 36 females; aged 8 to 69 years, an average of 45.2 years old. Patients diagnosed as spinal canal lesions in 62 cases, 11 cases of spinal stenosis, disc herniation in 8 cases, 4 cases of arachnoiditis, the other 15 cases to be investigated. CT Somatom CR3 Siemens, contrast agent concentration of 300mg / ml, a dose of 6ml / time. Patient lying on the side, head 10 ° ~ 15 °, with No. 9 lumbar needle in the waist 3-4 or waist 4-5
