椎管内疾病X线平片对诊断帮助不大,单纯脊髓造影亦仅能显示梗阻的平面,单向脊髓造影CT扫描对椎管内病变的诊断有很大的帮助,但如果椎管梗阻严重,造影剂不能通过梗塞部位时,就不能确定病变的另一端以及病变的范围。双向脊髓造影CT扫描就完全解决了这些问题。现将资料完整的经手术和病理证实的26例报道如下。 材料和方法 一、男20例、女6例,平均年龄40岁,病史8天～2年。临床表现主要为局部疼痛,进行性肢体麻木、无力,下肢瘫痪及大小便失禁等。 二、检查方法:上行性造影常规腰穿,下行性造影可行小脑延髓池穿刺或颈1～2侧方穿刺。所用X光机为普通胃肠机,造影剂为水溶性非离子型造影剂,如优维显、伊索显,碘必乐等。所用剂量浓度为300mg/ml,下行性脊髓造影用8～10ml,上行性造影用10～15ml。检查时一般先做下行性造影,再做上行性造影检查,如果病情危重者,可以分次进行。间隔
X-ray film of spinal disease is not helpful in the diagnosis of X-ray, pure myelography can only show the plane of obstruction, unidirectional myelography CT scan for the diagnosis of spinal lesions are of great help, but if the spinal canal obstruction is serious , The contrast agent can not pass the infarction site, you can not determine the other side of the lesion and the extent of the lesion. Two-dimensional myelography CT scan to completely solve these problems. Now complete data of 26 cases confirmed by surgery and pathology are reported below. Materials and methods First, 20 males and 6 females, average age 40 years old, history of 8 days to 2 years. The main clinical manifestations of local pain, progressive numbness, weakness, lower limb paralysis and incontinence and so on. Second, the inspection method: conventional radiography lumbar, descending contrast feasible cerebellar cistern puncture or neck 1 to 2 lateral puncture. X-ray machine used for the general gastrointestinal machines, contrast agents for the water-soluble non-ionic contrast agent, such as excellent Victoria significant, Aesopian, iodine and other music. The dose concentration used is 300mg / ml, descending myelography with 8 ~ 10ml, upstream angiography with 10 ~ 15ml. When the first general examination to do descending radiography, do upstream radiography examination, if critically ill, you can sub-level. interval
