| 摘 要： | 本文目的，通过将ＧＤ－ＤＴＰＡ直接注入蛛网膜下腔后进行脊髓造影ＭＲ扫描，探索一种新的ＭＲ检查方法，材料方法：对１１例患者进行ＧＤ－ＤＴＰＡ蛛网膜腔直接注射脊髓造影前后ＭＲ扫描，保持扫描序列不变。造影剂量为０．５～１．０ｍｌ，结果：所有患者脊髓造影后即刻扫描显示脑脊液信号反转，Ｔ１Ｗ高信号。Ｔ２Ｗ低信与，结论：小剂量ＧＤ－ＤＴＰＡ直接蛛网膜注射脊髓造影ＭＲ扫描是一种安全可靠的检查方法。对观察脑脊液动

| Abstract: | Purpose: To investigate a new method , MR imaging be performed after GD-DTPA subarachnoid administration. Materials and methods : 11 patients be examined with MR before and after GD-DTPA subarachnoid administration, and keep the same sequence. the doses are 0.5-1.0 ml.Results:The CSF signal of all the GD-DTPA mylogram patients shows negative compared with plain MR images after contrast administration immediately: T1 WI high signal,T2WI-low signal.Conclusion:Low dose GD-DTPA mylogram MR imaging is safe and perfect. It is important to evaluate the dynamic of the CSF circulation and some special CNS lesions. |
